April 9: Concept maps for Energy, Power and Work must be completed. Turn in
lab report for the Power Lab, and the open book assessment for Chapter 13 by
April 9. Class time made available to complete these assignments April 6, 7,
& 8 (two class periods each day), in addition to the time last week provided
for working on the Inspiration concept maps.
March 30: We start chapter 13 - Energy and Power today. Start by looking at
the Study Guide and by reviewing concept maps in the skills handbook (p.
758-759. We will be making Inspiration Concept Maps in the computer lab this
week to cover this chapter. We will also be preparing concept maps for Chapter
12 - Work so that we can relate Work, Power & Energy. You will also have to
read the chapter to be able to develop a good concept map.
March 10: We discussed the formulae for analyzing work (Work = Force X
Distance), Mechanical Advantage (Output force divided by Input Force), and
Efficiency (Output Work divided by Input Work X 100). Take time to read or re-
read the appropriate sections in your textbook.
March 9: Class time was spent reverse engineering Rube Goldberg machines
constructed by last year's 8th grade class. We are focusing on analyzing
simple machines and the work they do. Opportunities will be given to design
and analyze our own Nifty Lifting Machines.
March 3: Class time was given to work on assignments. Signed progress reports
were collected. Students not returning progress reports were reminded to have
them signed and return them to me.
March 2: Class time was given today to work on the Chapter ll application
work sheets. Additional time will be given on Tuesday, March 3. We discussed
buoyancy and the take home, open book tests were distributed. Updated
progress reports were distributed. We made hydrometers with Play-Doh and
straws demonstrating the effects of density on the hydrometer. This lab
should be noted in your journal along with your comments about the principles
inovlved.
February 27: Today we studied Bernoulli's principle. In class demonstration
which should be noted and explained in your journals: spool and note card. We
made Bernoulli atomizers using straws. There should be an explanation of how
the atomizer worked in your journal. Worksheets for Sections 11-2, 11-3 and
11-4 were distributed. Class time was given to work on 11-4. We will complete
these worksheets in class on Monday. You will be given a take home/open book
test for the chapter which will be due on Friday, March 6. The tests will be
distributed on Monday, March 2 after we conclude our discussion of buoyancy.
February 26 (Tangrams instead of bells)
February 25: Power surge caused loss of computers in the business office.
Mrs. Kennedy substituted for me and students were assigned to read Sections
11-3 and 11-4 and answer the questions at the end of each section in your
journals.
February 24: Today we discussed Pascal's principle, pressure in confined
fluid systems, hydraulic systems, pneumatic systems, and how to quantify
increased forces by the surface area of input and output devices. Question
#5, on page 357 should be answered in your journal. Demonstrations today
which should be described and analyzed in your journal: 1) balloon in the
bottle with and without straw; 2) The bottle filled with water, holes
punctured in side, with lid on, lid loosened, and lid off; 3) balloon in the
bottle after the holes were punctured. Computer lab time was given to print
work that is due/overdue (analyze and conclude for Inclined to roll, Stop on
a dime,and Forced to accelerate).
February 23: In class assignment: Read Chapter 11, Section 1. Take notes in
journal. Journal should include definitions of: pressure, Pascal, fluid
pressure, balanced pressures and answer questions 1-5 on page 351 in your
journal. Additionally, the second half of class, we discuss this material -
your journal should reflect notes taken during class discussion. STUDENTS
EARNING LESS THAN 50 POINTS ON THE ESSAY PORTION OF THE TEST HAVE UNTIL
TOMORROW TO SUBMIT CORRECTIONS/ANSWERS FOR ADDITIONAL CREDIT.
February 17: Turn in remaining worksheets for Sections 10-4 and 10-5 (total
of four). We will complete labs and data anlaysis prior to test on Friday,
February 20. The test will cover chapters 9 and 10.
February 10: Complete the final worksheets for sections 10-4 and 10-5.
Collect data for the Forced to Accelerate Lab (textbook); plan for the final
phase of the Stop on a Dime lab to be completed in PE on February 11. We will
have science on Wednesday, February 11. Thursday, February 12 will be bells
to replace the time captured today. Friday we do not meet. Our next science
class will be February 17 (Tuesday.) You should have completed all reading,
answering question at the end of each section of Chapter 10 in your journal,
all worksheets, rewrites/redos of graphs and assignments returned for
corrections. We will complete the data analysis of the labs on Tuesday and
Wednesday. Your test on Chapters 9 and 10 will be Friday, February 20.
Analyze and Conclude for the Inclined to roll lab are due Monday, February
9. There is one group that still needs to complete obtaining data.
Website assignment: Force Be With You - complete questions and submit by 5:00
pm Monday, February 9.
February 2-6: We will be working on Chapter 10. Labs will be done Tues -
Thurs.
Questions to be done in your journals and suggested completion dates: Chapter
10, Section 1 Review #1-4 (2/2); Section 2 Review #1-4(2/2); Section 3 Review
#1-4 (2/3); Section 4 Review #1-4 (2/3); Section 5 Review #1-4 (2/4). Class
time will be given on Monday, including computer time on Monday and Friday.
January 26-30: We completed entering data and graphing results. Graphs and
data tables were to be printed and turned in Jan. 30. We also observed three
demonstrations: 1. The Newtonian Demonstrator; 2. The coin, card and cup; and
3. The clip on a string. Observations were to be recorded in your journals.
Reading assignments in Chapter 10 will help you analyze the principles
involved in the three demonstrations.
Monday: January 26: I will be absent. You will have two class periods to
work, one in the computer lab, one in the classroom. I will have the
assignments for you on Monday.
We will be moving into Chapter 10 and there will be a test over Chapters 9
and 10. Test date has not yet been set.
January 19-23 we read Chapter 9 and performed lab activities. Class time was
given to put lab data into an Excel spreadsheet. We will be working with the
spreadsheets to analyze the data from our labs. Class time was spent
answering Questiosn 1 - 20 on a handout. This handout is important to have
for studying for a test on this material.
January 23: Questions #11-22 on pages 308 and 309 in your textbook. This
assignment is to be turned in and is due Tuesday, January 27.
Recent Assignments:
Class projects for Chapters 6, 7 and 8 were presented Monday and Tuesday,
January 12 and 13.
All written materials for your chapter projects are due no later than
January 19.
