Physical Science - Work

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

Wednesday September 4, 2019
Today we had a very short time together.  I began sharing information about the class 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?
Students were asked to bring a composition book for use in class -- due Friday.   Students were asked to get a scientific calculator, as well.  Students were offered 5 pts. of extra credit for bringing in a box of tissues -- due Friday.
I made a temporary seating chart.  We will reassign seats next week.

Thursday September 5, 2019
I reminded students that composition books are due tomorrow.  We continued with the class information listed for yesterday.   We did an activity called "Three Truths & A Lie."  I am getting to know my students and learn their names.  I gave an assignment for the students in the advanced group.  It is extra credit for everyone else: Write a one page essay, word processed.  Topic: Tell me about a place that is special to you.  Describe the place and explain why this place is important.  I would prefer an outdoor place, but if you really want to describe an indoor place, that is OK, as long as it is not your room at home.  Use proper writing standards.  Due on Monday.

Friday September 6, 2019
We set up our composition books for a science journal.  We added a title page, table of contents, In the News section, and "Measurement Notes."  We took notes.  We added to "In the News" a story about Jupiter being hit by an impactor on August 6.  We had a discussion and made a list of things that scientists measure and what units are used from the metric system.  Reminder, and essay is due for advanced students on Monday.  

Monday September 9, 2019
Our substitute teacher was Mr. Birge.  Mr. Birge collected essays due today.  Students watched a movie called "The Living Planet: The Building of the Earth."  Students recorded one new vocabuary word and two facts on a paper and turned it in.  

Tuesday September 10, 2019
We had an "In the News" item to record in our journals.  There will be a transit of Mercury, where Mercury goes in front of the Sun, on 11 November in the morning.  If it is not cloudy, there will be a telescope with a solar filter to view the transit.  We completed the student-generated list of things we measure and the units we use.  We looked at the beginning of a powerpoint about measurement.  We focused on how the metric system was invented.

Wednesday September 11, 2019
We started with taking a few notes on reading a scale.  We put this in the "Measurement Notes" section of the journal.  We added a section called "Density of Wood" to the journals and table of contents.  We reviewed how to use a balance to find mass and how to use l,w and h to find volume.  Students calculated the density.  We emphasized including labels and units on all measurements and calculations.

Thursday September 12, 2019
We took and corrected a pre-test on measurement.  This was recorded in the journals under "Measurement Notes."  Students were given a lab safety agreement.  The assignment is to have student and parent signatures on the safety agreement -- due tomorrow.  We watched "Bill Nye: Measurement."  Students recorded three important facts in their journals.

Friday September 13, 2019
I collected Lab Safety Agreements for a grade.  If it is turned in Monday, I will give on-time credit.  On a notecard, students listed seven names for lab team partners.  I will create a new seating chart for Monday.  We did an exercise in the "Density of Wood" lab.  If I cut the wood sample in half, we learned that the mass would be half the original, the volume would be half the original, but the density stays the same.  The conclusion is that "the size of the sample of a substance does NOT affect the density reading."  We added notes to "Measurement Notes" about reading rulers, spring scales, and graduated cylinders.  We copied the "metric staircase" into our journals.  This is a tool to use with unit conversion problems.  We solved three practice problems and two more independent work problems on unit conversions.  Example:  34.5 cm = 0.345 m

Monday September 16, 2019
I shared a powerpoint presentation on the ACEAP program expedition to Chile that I participated in in 2018.  Students learned about the American astronomy facilities in Chile and why we build them there.

Tuesday September 17 and Wednesday September 18, 2019
Students are invited to an extra credit telescope viewing session tomorrow evening (Wednesday).  We will look at Jupiter and Saturn.  I will be at the PMS football field at 8 pm.  Students were given their new seating arrangement.  We had an "in the news" item -- the second ever object in our Solar System that has come from outside the solar system -- this time a comet.  We reviewed the directions for the ten lab stations of the Measurement Lab.  Students made it through four stations today and recorded measurements and calculations properly.

There is curriculum night at NKHS starting at 6:30.  Come visit the telescope at PMS afterwards!

Thursday September 19, 2019
We practiced metric conversions using the metric staircase.  We completed the five practice problems that we started last Friday.  Advanced students completed seven practice problems.  Afterwards, we continued the "Measurement Lab" from yesterday and finished three more stations.  I will be collecting journals tomorrow after class for grading.

Friday September 20, 2019
I made a homework assignment for ADVANCED students.  Check out a book from me called "Change Over Time."  Read Chapter 60 and be prepared to discuss.  We will offer discussions during Study Session on October 1 and 15.  Attend one of these discussions.  There will be a written assignment on the reading in the future.  Students took a practice quiz today and recorded it in their journals.  The real quiz will be next Tuesday/Wednesday.  We finished the last three stations of the Measurement Lab.  Students turned in their journals for grading.

Monday September 23, 2019
We started with an "In the News."  Today is the first day of autumn, as the equinox occurred at 12:50 am this morning.  We discussed that there is a 12 hour day and 12 hour night, the Sun rises perfectly in the east today and sets in the west, and the pole of the Earth is perpendicular to the Sun.  We made a graph showing daylength in Poulsbo throughout the year.  It was a sine curve and we discussed the meaning of slope at different points.  I introduced the students to three different liquids.  They are water, a strong epsom salt solution and a weaker epsom salt solution.  We will identify them by determining their densities.  Then, we worked in groups to record questions, materials, and a procedure for our next lab -- The Density of Liquids.  Remember, the next day is our first quiz.

Tuesday September 24 and Wednesday September 25, 2019
Students got their journals back with three grades in the table of contents.  We added a section called "Fall Equinox."  We taped the graph from yesterday into the journals and recorded information off of the board about what happens at the equinox.  Students took a quiz.  Students finished working on their questions, materials and procedure for the Density of Liquid.  Students copied a final version of the question (purpose), materials list and procedure into the new section called "Density of Liquids."

Thursday September 26, 2019
Students got their quiz back and we went over the answers,  Quiz corrections are ONLY available for the next 5 school days.  Meet with Mr. Goar before or after school, during 1st lunch, or Study Session time for less than 5 minutes.  Students performed the Density of Liquids Lab.  They put data into their journals.  They identified the three liquids as water, weak epsom salt solution and strong epsom salt solution based on their densities.

Friday September 27, 2019
Students were given a handout listing various substances and their densities.  We discussed some of these substances.  Students recorded a new section in their journal called "Solubility."  We defined the words SOLUBILITY, SOLUTION, SOLVENT, SOLUTE, SOLUBLE, INSOLUBLE, CONCENTRATION, and SATURATED SOLUTION.  Students were given a worksheet and we solved problems #1 and #2 by calculating the concentrations of solutions.

Monday September 30, 2019
We cut and taped Friday's handout into the journals in the section called "Solubility."  I did a demonstration where I took a hot potassium nitrate saturated solution and put it in an ice bath.  Students witnessed the formation of crystals.  They recorded their observations in the Solubility section.  We did an investigation called "Measuring Volume," which we added to the table of contents.  We used gravel and measured the amount of airspace by adding it to water.  We will do a lab tomorrow called "Surface Tension of Water."  We added a section to our journals (and table of contents) and took notes on why water molecules have a magnetic attraction for one another.  We wrote a procedure for comparing how may drops of fresh water fit on a penny compared to soapy water.  The detergent destroys the magnetic attraction of water particles.

Tuesday October 1 and Wednesday October 2, 2019
Students saw a hydrometer, which can quickly measure the density of a liquid.  Students added a drawing into the Density of Liquids Lab.  We also added a drawing showing three solids either floating or sinking in mercury.  Students turned to the Surface Tension of Water Lab and recorded the manipulated, responding and controlled variables.  Students performed the lab and recorded data.  Afterwards, students wrote a conclusion.  At the end, we worked on the Solubility part of our journal.  We worked questions 3 and 5 together, and students worked on questions 4 and 6 independently.

Thursday October 3, 2013
Our "In The News" item was about a 110 million year old fossil dinosaur called a nodosaur.  It was found in Canada with impressions of skin (scales) and internal organs preserved.  We discussed Science and Engineering Practices and Cross-cutting Concepts that scientists use.  We added a new section to our journal called "Pendulum Lab" and we discussed the manipulated variables that might affect the period of the pendulum.  In lab teams, students recorded their choice of a manipulated variable and identified responding and controlled variables.  Students worked on writing a procedure, a materials list and a prediction of the results.  We will continue planning tomorrow and will perform the lab next Tuesday-Wednesday.

Friday October 4, 2019
We finished planning the Pendulum Lab and students recorded their final procedure, materials list, and a hypothesis in their journals.  Classes that finished this work early played a game at the end.

Monday October 7, 2019
Our substitute teacher was Mr. Hundley.  Students watched "The Living Planet: The Frozen World."  Students turned in a paper with two things they learned and one new vocabulary word.

Tuesday October 8 and Wednesday October 9, 2019
Our substitute teacher was Mr. Hundley.  Student performed the Pendulum Lab and recorded data in their journals.  Students then shared out the results and decided which variables had an effect on the period of the pendulum.  Students recorded each team's data in their journals.

Thursday October 10, 2019
Today we reviewed what we learned in the Pendulum Lab.  We started a new section called "Graphing Skills."  Students learned how to select the type of graph which is appropriate (bar graph, line graph, pie graph, histogram or scatter plot), learned how to decide which variable goes on the x and y axis, and learned how to scale the axes.  We will continue with graphing skills tomorrow.

Friday October 11, 2019
We watched 6.5 minutes of a video about the Very Large Array.  It is a radio telescope in New Mexico.  Students completed their graphing skills notes with information on plotting points, connecting data, and giving the graph a title.  Students created a line graph with data from the "Pendulum Lab."  When finished, this was added to the Pendulum Lab section.  Students turned in journals for grading.

Monday October 14, 2019
While grading journals over the week-end, I noticed that I made a mistake and did not give enough time on the "Solubility Questions."  Today, I handed back the journals and students completed this work.  I will grade the journals over the next two days.  Using a power-point, the class reviewed for the upcoming unit test on Tuesday and Wednesday.  Students took notes for study.

Tuesday October 15 and Wednesday October 16, 2019
Students took a unit exam.  When they finished, they got a book "Conceptual Physical Science."  They read pages 16-20, which was about mechanics, speed and velocity.  Students added "Mechanics" to their journals, and answered three questions from page 21.

Thursday October 17, 2019
We added information into the "Mechanics" section of the journal.  I walked across the room and using the distance and time, calculated average speed.  We recorded the "triangle" version of s = d/t so that we can solve for any of the three variables.  We looked at a powerpoint on speed and velocity and took some notes.  We made a list of various speeds and converted between mi/hr and km/hr.  The list went from snails to spacecraft.  We did four practice problems in the journals concerning speed.

Friday October 18, 2019
Student got the test from earlier in the week back, and we went over each question.  Students added questions 5-7 on speed/distance/time in their journals.  We discussed the trans-America bicycle tour I did and used the average speed to create data, which we expressed as a line graph.  We learned that the slope of the line indicates the speed.  Students also created their own data and graph choosing their own speed.
