Assignments for 11/9

Periods 1 and 2

Then read section 5-3 pages 112-115 and do problems 21 & 22 on page 131.  (1st period, you had this for homework, come together in small groups. Since you’ve had more time to study it, leave hints for 2nd period on some white boards.  We’re stronger as a team.)  Turn in your answers at the end of the period.

 

Period 5:

Read up on the James Webb Telescope.  It completed some major testing milestones this week.

  • What testing has it undergone?
  • What still needs to be tested?
  • Why are we testing this particular telescope so throughly?
  • Why are some scientists opposed to this telescope?
    • Where are we putting it?  Will it be easy to get to? Could we repair it?
  • What science do we hope to accomplish with this device.
    • Will we be able to directly image planets outside of our solar system?

Turn these questions in on paper at the end of the period.

Assignments for 11/2/2016

1st and 2nd Period:

Please complete the following lab on rotation using the PhET Motion in 2D and Ladybug Revolution simulations.  These should work on the Macbooks that someone should have retrieved from the library. (No macbook cart?  Someone should go get it from Mrs. Renfro!)  You may work in groups of 2, and you may need to if some of the computers will not run the simulation.  This will not work on the chromebooks.)

Answer the questions on a separate sheet of paper and turn it in at the end of class along with the questions that I assigned for homework last night.

  • Period 1: Page 130, 1, 3, 5, 18, and 66.
  • Period 2: Page 130, 1, 3, 5, 6, 7, and 9.

Assignments for 10/21

Period 1:

I understand that you had some trouble with the problems I assigned.  Sorry about that.  Today you have a lab about the main idea from yesterday’s reading:

  1. Energy conservation means that you can trade one form of energy for another.  Kinetic (moving) energy can be traded for Potential (position) energy and vice versa.
  2. Work is how much energy your giving to an object.  Maybe you’ve lifted it and given it Potential Energy.  Maybe you pushed on it to make it move faster and gave it Kinetic Energy.

The lab today focuses on that relationship between the two.  Use the  Energy Skate Park simulation to complete the lab that the substitute has. (The Lab looks like this, but use the paper copies!)  This should take about 40min.  Then try the problems from yesterday again.  As always, feel free to work in groups on both.  If you have questions, email me!

Please make sure the laptops get plugged in at the end of class!!!

Period 2:

Today you have a lab on Hooke’s Law.  You’ll be using the PhET simulation Masses & Springs to complete the worksheet that the substitute has.  (The lab looks like this, but complete it on the paper the sub gives you.)

You’re trying to find “k.”  The constant that tells you how stiff a spring is, or in terms from yesterday’s reading; how much work you’ll have to do to stretch or compress the spring.  Feel free to work in groups on this.  It should take you about an hour.  Once you’re done, work on any problems left over from yesterday.  If you’re confused, email me!

Please make sure the laptops get plugged in at the end of class!!!

Period 5:

Read the following passage on Jupiter  then answer these questions.

  1. Describe the appearance of Jupiter’s atmosphere. Which features are long-lived and which are relatively fleeting?
  2. What causes the belts and zones in Jupiter’s atmosphere?
  3. Compare and contrast the surface features of the four Galilean satellites, discussing their geologic activity and their evolution.
  4. Why are numerous impact craters found on Ganymede and Callisto but not on Io or Europa?
  5. Discuss why astronomers believe that Europa, Ganymede, and Callisto may harbor some sort of marine life. Why do they not expect any life on the surfaces of these worlds?

I hope to collect these answer, along with your work from the last 2 days on Monday.  If you have any questions or need help, email me!
