Physical Science - Work

This is where you can find information on what we have done in class each day:

Wednesday September 6, 2017
Today I shared my syllabus and answered:
1.  Where do I sit?  2.  What are the rules?  3.  What are we going to be doing this year?  
4.  How do I earn my grade?  5.  Who is the teacher as a person?  6.  Will the teacher treat me as a human being and with respect?
For a grade, students will turn in the syllabus with a parent signature and safety agreement signed by parent -- due Friday.
Students were asked to bring a composition book for use in class -- due next Monday.    

Thursday September 7, 2017  
I reminded students that composition books are due next Monday.  I gave an assignment for homework (DUE TOMORROW).  Students are to measure a piece of string and cut it to a length of two cubits and two spans.  Students were shown how to measure the string.  Students were invited to join the "Advanced Option" in physical science.  That application, handed out today, is due next Wednesday.  For extra credit, students can write an essay about themselves called "A million words, or less."  I want to know about their learning styles and interests in science.  The due date for this is Monday.  We did a name-learning activity and played a game of "two truths and a lie."  I showed students how to access this blog to use [especially when they are absent from class].

Friday September 8, 2017
I checked for two parent signatures and the "string" assignment.  I will put the grades into the gradebook on Saturday.  I taught the students about the huge effect that missing grades have in the gradebook.  We brainstormed and made a list of things that people measure. I highlighted three important ones -- mass, volume and length (or distance).  Students were given a pink packet for Unit 1 on measurement.  Students took notes about meters, liters and grams on the back side of the packet.  Students watched the first part of a movie about measurement and answered questions on page 2 of the packet.  Students will keep their packets until they are completed.

Monday September 11, 2017
Students were asked to look and record the location of the sunrise in the morning.  Is it in the east?  Exactly?  Since Hostmark goes straight east, it can be used as a guide.  I learned some names.  We organized our composition books (journals) by adding a title page and a table of contents.  We added the "Measurement Lab" to our table of contents and measured the string of 2 cubits and 2 spans in units of cm.  We learned the requirements for writing data in a lab report.  We discussed the stations for tomorrow's measurement lab.  

Tuesday September 12, 2017
Students went through stations in the "Measurement Lab."  There are nine stations, and students completed five of them today.  They measured different things (length, width, mass, volume) and did calculations (area, volume, density).  Students recorded their data in their journals.

Wednesday September 13, 2017
Students are invited, for extra credit, to view Saturn through a telescope.  We will be set up at the Poulsbo Middle School football field at 8pm.  For extra credit, students will need to write a short reflection.  We added an "In The News" section to our journals.   Students added information about the Cassini Probe crashing into Saturn on Friday.  We completed three of the last four stations of yesterday's Measurement Lab.  Students recorded their data in their science journal.

Thursday September 14, 2017
Students are invited, for extra credit, to view Saturn through a telescope.  We will be set up at Kingston Middle School football field at 8pm.  For extra credit, students will need to write a short reflection.  Students were given a 3x5 card to write names of those who might make good lab partners.  I will put together a new seating chart for Monday.  Students finished the last station of the Measurement Lab.  Journals will be turned in on Friday for grading.  Students were taught the skill of metric unit conversions.  Students completed the unit conversion page in the pink packet -- problem #3  -- the first nine problems.

Friday September 15, 2017
We discussed the Cassini Probe crashing into Saturn this morning.  We did a practice quiz and corrected it in class.  The real quiz will be Monday.  Students added "Density of Liquids" to their journal.  They recorded measurements and calculations to find the densities of two liquids.

Monday September 18, 2017
Students were given their seating in their new lab groups.  We discussed errors made in the Measurement Lab.  Students were taught how to raise a grade that is too low for student's expectations.  Students completed page 4 in the pink packet.  Students either calculated the density of copper and aluminum (in Measurement Lab), or, if this was complete, were given a piece of wood to calculate the density (extra credit).  The quiz scheduled for today was postponed until tomorrow.

Tuesday September 19, 2017
We completed two pages of unit conversion problems and measurement questions in our pink packets.  Students took a quiz.

Wednesday September 20, 2017
In the news, the fall equinox is Friday and it happens at 4:02 am PDT.  We discussed what happens at an equinox and I created a sine curve of daylength over a year.  We looked at the slope of the graph as a measure of how fast the daylength is changing.  Students got their quiz back from yesterday and we went over questions.  We discussed the policies of retaking tests.  Students turned in their pink packets and I passed out Unit 2 Packet (white) about the Scientific Method and graphing skills.  We read and discussed the Scientific Method page.

Thursday September 21, 2017
For periods 4 and 6, the substitute teacher was Mr. Birge.  Students watched a movie called "Living Planet - The Northern Forests."  Periods 1,2 and 3 watched "The Living Planet - Jungle."  Students wrote down two things they learned and one (or more) unknown vocabulary words.  Students turned in their binder paper with the answers.

Friday September 22, 2017
Students completed page 4 of the white packet.  We discussed the potential manipulated variables for the "Bouncy Ball Lab."  Students recorded their ideas on the Bouncy Ball page of the white packet.

Monday September 25, 2017
Extra credit is offered for students who bring in a box of tissues.  Students recorded, in their "Density of Liquids" lab the identity of liquids A  and B.  We brainstormed examples of substances with high and low density.  I passed a list of substances and their densities and students taped the list into their journal for reference.  We wrote down a list of Characteristic Properties -- properties used for identification.  The list included density, boiling point, melting & freezing point, and appearance or color.  We watched a movie on the Scientific Method and answered questions on page 2 of the white packet.

Tuesday September 26, 2017
We played a game of "telephone."  We did a Lego building activity where students wrote a procedure for their construction.  Another lab group used the procedure to try to build the exact same structure.  We learned that it is important to be very specific in the procedure steps.  We played a game of "bagels."

Wednesday September 27, 2017
We completed the page "Bouncy Ball Lab" in the white packet.  We added "Bouncy Ball Lab" to the table of contents of our journals.  In the journals, students wrote 1.) their choice of manipulated variable, 2.) hypothesis, 3.) procedure, 4.) a data table.  We discussed what makes a good procedure -- this was the emphasis of the lesson.  If students did not finish this writing in class, it is homework.

Thursday September 28, 2017
I shared information on a poster about light pollution and how to preserve dark night skies.  We performed the Bouncy Ball Lab.  Students recorded the data in their journals.  Students calculated the % return distance on the first bounce.  Students averaged the data and we discussed what goes in the conclusion.  Students wrote their conclusion for the lab.

Friday September 29, 2017
Students learned about graphing skills.  We completed the "Graphing Skills #1 and #2 in the white packet.  We performed the lab called "How is the Surface Tension of Water Affected by Soap?"  Students counted drops of fresh water and soapy water that fit on a penny.  We will continue taking data for this lab next Monday.

Monday October 2, 2017
We discussed plans students have for the 13th year -- the year after high school students graduate.  We went over some of the issues students had with writing a quality procedure, hypothesis and conclusion in the density of liquids lab and the bouncy ball lab.  Students were given time to finish the "How is the Surface Tension of Water Affected by Soap" lab.  Students calculated the average number of drops of fresh water and soapy water that could be held by a penny.  Student wrote a conclusion for the lab and answered four post-lab questions.  The work was recorded in the White Packet.

Tuesday October 3, 2017
We looked in the white packet at the lab called "Period of a Pendulum."  We identified possible manipulated variables for the experiment and recorded them in the white packet.  We entered, in our journals, a title, a purpose, a list of variables (manipulated, responding, controlled).  We wrote a hypothesis, a procedure and a data table.  Students got part way through collecting data.

Wednesday October 4, 2017
In the News, the James Webb Space Telescope is going to delay its launch into space until 2019.  Students were given more time to collect data in the pendulum lab.  After averaging the data, students shared the results.  All of the different team's data was entered into the journals so that students can make a conclusion about 1.) string length, 2.) mass at the end of the pendulum, and 3.) the angle of release.  We will work on those conclusions tomorrow.  There is a quiz coming on Friday -- we will review tomorrow.

Thursday October 5, 2017
There is a quiz tomorrow -- we went over what to study in class.  Students wrote a conclusion to the Pendulum Lab in their journals.  We discussed the vocabulary quantitative, qualitative, inference and observation.  We finished Graphing Skills #2 and started Graphing Skills #3 in the white packet.

Friday October 6, 2017
Students took a test.  Afterwards, students finished the pages in the white packet called Graphing Skills #3, #4, #5 and #6.  Students turned in their white packet if they finished.  If it is unfinished, students can turn it in for full credit on Monday at the beginning of class.

Monday October 9, 2017
Students took some notes in their journals about "Laws of Motion."  We discussed speed, acceleration and Newton's Three Laws of Motion.  Students were given a green packet (Packet #3) and we watched a movie about Laws of Motion.  We filled in the questions that went with the movie in the green packet.

Tuesday October 10, 2017
I started class with a short discussion of college costs and how to pay for college.  Students got their tests back from Friday and we went over questions.  I highlighted misconceptions about theories.  Students were given a reading packet to answer the questions on page three of the green packet.  We worked as a class on the definitions on page four of the packet.

Wednesday October 11, 2017
We opened with a discussion about how changing the power of a ferry boat affects its speed.  We looked at the "Speed" lesson in the green packet.  Students answered some of the questions on the"homework" page of the green packet.  I demonstrated how the "Marble Motion" lab will work.  We will be doing the lab tomorrow measuring speed of a rolling marble.

Thursday October 12, 2017
Students recorded data for the "Marble Motion" Lab in the green packet.  There were six questions to answer with the lab.  With the remaining time, students completed the "Homework" page in the green packet.

Friday October 13, 2017
We started by graphing the speed of two hamsters in a race.  We learned that the slope of a distance vs. time graph gives you the speed.  This graph is in the green packet.  We completed the seven word problems in the green packet -- it is called Homework I.  We learned how to calculate acceleration and we learned the units of acceleration.  Students started the "Velocity & Acceleration" page.

Monday October 16, 2017
Students performed the "Acceleration Lab" in the green packet.  Students recorded times for marbles falling down ramps.  Students calculated acceleration and produced a graph of distance vs. time to show the acceleration of the marble.  The graph produced a curve -- a changing slope to show that the marble was accelerating.  Data and graphs are found in the green packet.

Tuesday October 17, 2017
There was a power failure which lasted until about 2 pm.  A sincere thank you to students for safe behavior in a very dark classroom.  There was no lesson, but I credit several students for using the time wisely to catch up on work, or do other productive work.

Wednesday October 18, 2017
Students were given a lesson on making distance vs. time graphs with changing speeds.  Students worked in the green packet on "In Class Activity on Position-Time Graphs."  Students were given time to finish Monday's acceleration graphing activity.  Students with extra time worked on Homework I page.  We will be finishing the green packet tomorrow.

Thursday October 19, 2017
We had two "In The News" items.  The dwarf planet Haumea was discovered to have a ring around it.  And gravitational waves were detected from a merger of two neutron stars.  We completed two pages together from the green packet -- "Homework II" and "Accuracy, Precision & Measurement."  Students had some additional time to finish the green packet.  Some students turned it in today, but it is due tomorrow at the beginning of class.  There is a quiz on speed, acceleration and graphing tomorrow.  We reviewed for the quiz.

Friday October 20, 2017
Students turned in their green packets (Unit #3) on speed, acceleration and graphical interpretations of motion.  Students took a test.

Monday October 23, 2017
Students were given their tests back from Friday and we went over questions.  Students were given a golden colored packet about Newton's  Laws of Motion.  We completed the demonstrations called "Balloon Rally" and "Wacky Washers" and filled in the questions about these activities.  I used an air track to demonstrate Newton's Laws.  Students completed the Discussion Questions #1-3 on the same page as "Balloon Rally."

Tuesday October 24, 2017
Our substitute teacher was Mr. Chase.  Students watched a movie and took notes on a piece of binder paper, which they turned in.  The movie was "Planet Earth: The Building of the Earth."

Wednesday October 25, 2017
As a class, we finished the Discussion Questions in the golden packet.  Students used cars and ramps to record data in a lab activity called "Newton's Race."  As the mass of the car changed, the force of gravity increased and the car rolled farther.  We noted that the speed of the car was NOT affected by the mass of the car.  Students recorded their data in the golden packet.

Thursday October 26, 2017
I am the advisor of a new club at NK -- The Science Olympiad Club.  Students are welcome to join if they are interested in competing in a Science Olympics.  The first meeting is next Monday after school.  Extra credit in science is offered.  I read two paragraphs written by NASA astronaut Scott Kelly explaining how he decided to become an astronaut.  We performed "Newton's Second Law Lab" using the air track.  Students took data to measure the acceleration of the car when the force increased and when the mass increased.  The information was recorded in the golden packet.

Monday October 30, 2017
We listened to a description by NASA astronaut Scott Kelly about what it is like to launch into space.  Students took notes, on the last page of the golden packet, of "Force Diagrams."  Students used the equation for acceleration to answer six questions on the page called "Using Acceleration Equations."  We did four questions together, and students did two questions on their own.

Tuesday October 31, 2017
Students completed the second-to-last page in the golden packet called "Homework."  Because the quarter ends on Friday, I offered an extra credit.  Students ripped out of the golden packet a page called "Physics4Kids Internet Activity."  If it is turned in by Friday, I will add 10 points to the grade.  Students turned  in the completed golden packet.  I gave students a tan packet called "Unit 5."  It is about forces and gravity.  We completed pages 3 and 4 which are called "Nature of Forces" and "Balanced and Unbalanced Forces."

Wednesday November 1, 2017
Looking on the page (in the tan packet) called "Newton's Second Law and Weight," I pointed out an error in the lesson.  The text said that in space things are weightless because there is no gravity.  This is false, and I provided examples.  Students watched a movie on Forces and Gravity and answered the questions on page 2 of the tan packet.  We answered one additional question in the packet -- Why is F = ma not entirely correct?

Thursday November 2, 2017
Students added "Gravity" to their notebooks.  We identified and discussed the variables which determine the gravity on other worlds and recorded a formula for gravity:   G = k (m1)(m2)   /  dist sq.  Students watched "Bill Nye: Gravity" and recorded 23 answers to questions in the tan packet.

Friday November 3, 2017
Students completed the pages called "Notes on Forces, Gravity, Free Body Diagrams -- the first page and the first question on the second page.  We will finish this part of the tan packet next week.  Students turned their tan packet to the lab called "Force of Gravity on Different Masses."  We completed the entire lab including making a graph (together).

Monday November 6, 2017
I demonstrated a computer program called "Starry Night Pro."  We looked at the night sky projected upon the screen.  We looked at planets, deep sky objects and the motion of the stars over a night.  After that, we worked on the 5th page in the tan packet.  It had two columns of questions relating to forces, masses and acceleration.

Tuesday November 7, 2017
Students went to a computer lab and worked on two PHET simulations.  The first was called Gravity Force Lab and the second was called Gravity and Orbits.  Students answered questions in the tan packet.  The PHET questions went for four pages, and I did not give enough time to finish.  The expectation is that students completed two pages.  The final two pages can be done at home for extra credit.

Wednesday November 8, 2017
Students added a section into their journals called "Momentum."  We took notes about momentum, its formula and units, and performed to calculations of momentum.  I demonstrated how we will perform the Momentum Lab.  Students wroted a procedure and made a data table for the lab.

Thursday November 9, 2017
We had an "In The News" item.  Scientists recently detected the first interstellar object to travel through the Solar System.  We watched a YouTube video of VSauce - Which way is down?  Students chose two of the following three questions to answer in their journal:
1.) What would happen to the orbit of the Earth if the Sun turned into a black hole?
2.) When he moves the plastic ball and the more massive steel ball, what does this say about inertia?
3.)  Why does he say that on the space station you are neither weightless nor in zero gravity?
We performed and took data for the "Momentum Lab" (see yesterday's entry).

Monday November 13, 2017
We will have a quiz tomorrow.  Students looked at a list of vocabulary words that they should know.  All math formulas will be provided.  Students worked in their tan packets completing "Notes on Forces, Gravity, Free Body Diagrams" and "Review Packet for Quiz."  Students worked on the question page for "Newtons Second Law and Weight."

Tuesday November 14, 2017
Students took a quiz.  With the time after the quiz students completed the page in the tan packet called "Understanding Weight and Mass."  The tan packet will be ready to turn in tomorrow.

Wednesday November 15, 2017
In the classroom, I demonstrated the PHET program called "Forces and Friction" and students completed questions #1 and #2 under the category called "Tug of War" in the tan packet.  Students calculated the momentum from different trials in the Momentum Lab (last Thursday).  We analyzed the factors that make a change in momentum.  Students wrote a conclusion for the lab in their journals.

Thursday November 16, 2017
Students got their test back from Monday, and we went over questions.  Students watched Bill Nye - Momentum.  I handed out Packet #6 (Green) and students completed the questions from the movie (page 2).  I collected the tan packet (#5).

Friday November 17, 2017
We discussed the difference between elastic and inelastic collisions, and students recorded the vocabulary in their journals under the "Momentum Lab."  Students used computers to perform the Collision Lab.  The data was recorded in the green packet, and student answered the lab questions in the packet.

Monday November 20, 2017
In a last minute change of lesson plans, students watched a movie.  It was "The Living Planet" and the episode was "Seas of Grass."

Tuesday November 21, 2017
Students completed the Friction Lab in the green packet.  Students used a Vernier probe and computer to measure friction.  Students answered four questions: 1.) Which is larger, non-moving friction or sliding friction. 2.) Does changing surface area have an effect.  3.) Is friction different on different surfaces (table, cardboard, sandpaper), and 4.) Will adding weight make a difference in friction?  Students turned in their green packet and their journals.

Wednesday November 22, 2107
Happy Thanksgiving!  We played a game of Jeopardy in class today.

Monday November 27, 2017
Students added "Work and Power" to their journals.  We took notes, including the mathematical formulas for work and power.  Student were given the Unit 7 Packet (blue).  Students completed the questions on page 2 of the packet.

Tuesday November 28, 2017
We looked at a few images from Astronomy Picture of the Day.  Students added a section in their journals called "Potential and Kinetic Energy."   We discussed how a bouncing ball or a roller coaster provides a good example for the transfer of energy between kinetic and potential.   Students watched a video called "Physics of Roller Coasters" (available on YouTube) and answered questions on page 9 of the blue packet.

Wednesday November 29, 2017
Students were given answers for some of the questions for the "Roller Coaster Design Lab" and recorded the information in the blue packet (pg. 10-11).  Students went to the computer lab to learn how to use the "Energy Skate Park" simulation of a roller coaster.  We will go to the computer lab on Monday to complete the assignment, which begins on page 12 of the blue packet.

Thursday November 30, 2017
Students recorded the formulas for Gravitational Potential Energy and Kinetic Energy in their journals under "Potential and Kinetic Energy."  We discussed how to save the planet Earth if it were threatened by a large asteroid or comet impact.  We used the idea of striking the object with a collision to consider the difference between momentum and kinetic energy.  Students looked at some Astronomy Picture of the Day images and we ran the "Interactive Universe" program.  As a class, we worked the questions 1-4 of the blue packet (pages 3 and 3A) concerning weight on other planets and gravitational potential energy.

Monday December 4, 2017
Students completed the pre-lab questions on pages 10-11 of the blue packet.  We went to the computer lab and used "PHET: Energy Skate Park" to design a roller coaster.  Students completed pages 11-15 in the blue packet.

Tuesday December 5, 2017
I announced a quiz for this Friday.  We completed math questions about energy, work and power on pages 4 and 6.  We completed the vocabulary on page 8.

Wednesday December 6, 2017
The "In The News" item was about Voyager 1 spacecraft firing  thrusters for the first time in 37 years.  The spacecraft will soon adjust its attitude.  We completed page 5 in the blue packet.  The blue packet will be completed on Thursday and turned in on Friday.  There is a quiz on Friday.  Students should study the vocabulary on page 8 of the blue packet and know the units for the different measures we have studied.  Students will NOT need to memorize any of the math formulas.

Thursday December 7, 2017
We looked at three YouTube videos.  They were about momentum and weightlessness.  We did a review for tomorrow's quiz and I shared what the students need to study.  Students completed pages 7 and 3a in the blue packet, which completes the unit.  Students will turn in the blue packet tomorrow.

Friday December 8, 2017
I collected the Unit 7 Packet (blue).  Students took a test.

Monday December 11, 2017
Students got their test back from Friday and we went over questions.  Students added "Simple Machines" to their journal.  We used an inclined plane as an example of calculating mechanical advantage and the ratio of forces and distances that are involved when using a simple machine.

Tuesday December 12, 2017
Students were given Packet #8 (yellow packet).  We watched the movie about Compound Machines and answered questions on page 12 of the yellow packet.  We completed the questions on page 5.  We watched a YouTube video showing the world record Rube Goldberg device.

Wednesday December 13, 2017
We did a lab about mechanical advantage of simple machines.  Students recorded their observations and data in the journal under "Simple Machines."  We learned how to construct ramps (inclined planes) which gave a mechanical advantage of 2:1, 3:1, 4:1 and 5:1.  We built the ramps, calculated the expected forces, and  measured the forces needed to maintain a car on the ramp.  We also used a compound pulley system with a 7:1 mechanical advantage.  We calculated the weight of the hanging mass and the force expected to maintain the pulley system in stasis.  We measured the force to maintain the pulley system.

Thursday December 14, 2017
We watched the movie "A Year In Space" about astronaut Scott Kelly spending a year aboard the ISS.

Friday December 15, 2017
We finished the last five minutes of yesterday's movie.  We completed a worksheet called "Branches of Science and Branches of Medicine."  I collected journals to grade the Simple Machines Lab.

Tuesday January 2, 2018
Students were reminded of the deadline that comes with the end of the semester -- January 26.  Students were given a golden colored packet -- Packet #9, which is about energy transformations.  Students added "Energy" to the table of contents of their journals.  We brainstormed different forms of energy and recorded the ideas in the journals.  Students watched a movie "Heat and Energy" and answered questions on pages 2-3 of the packet.

Wednesday January 3, 2018

All of the following information was recorded in journals under the section called "Energy."  We compared heat and temperature in three different thought experiments.  We discussed how heat transfer happens.  We looked at the three temperature scales (K, F, and C) and identified some important points like the freezing and boiling points of water.  We recorded the mathematics of how to convert between K, F, and C

Thursday January 4, 2018
Students were offered extra credit in the "Energy" part of their journal.  I gave students four stars.  They are to look up the temperature in degrees Kelvin and convert each to Celsius and Fahrenheit.  Today we looked at the temperature of five animals and converted each between C and F.  We looked at a powerpoint presentation about energy conversion and, at the end, took a quiz.  All of this work was put in the journal under "Energy."

Friday January 5, 2018
We watched the Bill Nye movie on Energy.  There were questions to answer in the golden colored packet.

Monday January 8, 2018
Students performed the "Energy In Food" lab and recorded the results in their journals.  Students were given a handout with the directions.  Students built a calorimeter and collected the heat from burning marshmallows and burning walnuts to determine whether foods high in sugar or foods high in fat/oil had more energy.

Tuesday January 9, 2018
We took notes about "specific heat" of different substances.  If the calorimeter from yesterday did not have water in it -- if it had alcohol or aluminum or gold, how much temperature change would have occurred?  Specific heat helps us to know.  We shared our results and recorded a class average for calories per gram for marshmallows and walnuts.  We played a game of "Family Feud" to list the reasons that our results do not match what the internet gives for the heat energy in sugar (5000 cal/g) and fat/oil (9000 cal/g).

Wednesday January 10, 2018
We looked at some movies from Astronomy Picture of the Day.  These included, Mercury, Jupiter and the Crab Nebula.  I made a correction to the information given last  week -- we changed the energy of raising the temperature of ice or steam.  Students added four questions to the "Energy of Foods" Lab.

Thursday January 11, 2018
Students went to a computer lab and took the "Star Reading Test."

Friday January 12, 2018
Students went to a computer lab and took the "Star Math Test."

Tuesday January 16, 2018
Students were given a new packet.  It is the green Unit 10 packet about Static Electricity. Students took notes on the front cover of the packet which answered the question: "What is electricity."  The explanation involved a drawing of the structure of a copper atom.  We also answered eleven questions on page 2 of the packet.  I announced a quiz for this Friday which will cover Energy and Electricity topics.

Wednesday January 17, 2018
We performed a lab on the "Triboelectric Effect."  The lab, in the green packet, is called "Activity on Electrostatic Forces."  Students collected data and recorded it in their green packet.

Thursday January 18, 2018
We watched a movie called "Raging Planet - Lightning."  Students answered two pages of questions in their green packet.

Friday January 19, 2018
We looked at a short video of nine different static electricity experiments.  Students took a test.  We used a Van de Graaff generator to produce static electricity.

Monday January 22, 2018
Students got their test back from Friday and we went over questions.  Students added "Electric Circuits" to the table of contents of their journal.  Students took notes on the vocabulary words: closed circuit, open circuit, short circuit, parallel circuit, and series circuit.  We distinguished between alternating current (AC) and direct current (DC).  Students got packet #11 (blue).  On pages 13-15, we completed a circuit lab which compared parallel and series circuits.

Tuesday January 23, 2018
Students were given a packet of practice questions to help prepare for the final exam this Thursday or Friday.  The practice questions will NOT be collected or graded, but students can ask questions tomorrow if there are any confusions.  We answered questions in the blue packet on pages 2-3 and added notes to the journal under "Electric Circuits."  This included formulas for electric power and electric energy.  We watched a movie about electricity and answered questions in the blue packet on page 1.

Wednesday January 24, 2018
Students asked questions from their review packet and these questions were answered.  We added some notes into our journals (in Electric Circuits) about Ohm's Law and conductors vs. insulators.  Students were assigned pages 4 and 21 in the blue packet.  The blue packets will be collected after the final exam.

Thursday January 25, 2018
Periods 1 and 3 took finals and turned in the blue packets.

Friday January 26, 2018
Periods 2, 4 and 6 took finals and turned in the blue packets.

Monday January 29, 2018
This begins the second semester.  Students filled out 3x5 cards to let me know who would make a good lab partner.  I will make new seating charts soon. Students added "Molecule of the Day" to their journal.  Each day, for the next ten weeks, I will present a new molecule.  Today's molecule was hydrogen gas.  Students added "Atomic Structure" to the table of contents of the journal and we took notes about how to draw different atoms.

Tuesday January 30, 2018
Today's molecule of the day is oxygen gas.  We looked at a discharge tube with hydrogen inside and discussed its spectrum.  We continued the notes of "Atom Structure" and began making a poster.   Each student has their own atom and we will continue with the poster tomorrow.

Wednesday January 31, 2018
There is no molecule of the day today.  We worked on the Atom Structure poster.  I shared the naturally occurring isotopes of each student's atom.  Students started to construct their poster for their atom.

Thursday February 1, 2018
Today's molecule of the day is nitrogen gas.  We discussed nitrogen compounds that plants use for growth.  We used the blue packet pages 7-9 and performed the "Lemon Lab."  We used two electrodes in the fruit (and in potatoes and apples) and used a multimeter to measure the voltage of the electric current.  Students answered some questions on pages 7-9 and turned in the three pages.

Monday February 5, 2018
Our substitute was Ms. Veach.  Students watched "The Living Planet -- Community of the Skies."  Students recorded two things they learned and one new vocabulary word.

Our molecule of the day (#5) was glucose.  We listened to an out-loud reading of an article and two youtube videos about coral reef bleaching events which are tied to increasing ocean temperatures.  Students wrote about what they learned in their journals under "In The News."

Our molecule of the day  (#6) was methane.  I taught the vocabulary for beginning chemistry using a power point presentation.  Students recorded the vocabulary in their journals under the heading "Matter."  The vocabulary included: matter, non-matter, pure substance, mixture, element, compound, homogenous mixture, heterogeneous mixture, solutions, suspension, solvent, solute, saturated solution, unsaturated solution, concentration, physical change and chemical change.  Examples were given for each.  Students were given a bit of time to finish the atom poster.  It is due tomorrow.

Our substitute teacher was Mr. Schlosberg.  Students watched the movie "The Living Planet" and the episode was "Sweet Fresh Water."  Students wrote two things they learned and one new vocabulary word and turned it in.

Tuesday February 13, 2018
Our substitute teacher was Mr. Hundley.  Students watched the movie "The Living Planet" and the episode was "The Margins of the Land."  Students wrote two things they learned and one new vocabulary word and turned it in.

Our counselling staff visited for the entire period and discussed registration for sophomore year classes.  The registration date is March 5 and students need to have made their choices by then.  There is an evening information night here at NKHS on February 22 at 6 pm.

Thursday February 15, 2018
We had two molecules of the day.  Molecule (#8) is propane and (#9) is butane.  Students were given a periodic table of the elements which was then taped into the last page of the student's journal.  Students started working on the questions on page 13 of the yellow packet.
