Today, we got our Circular Motion, Work and Energy Test back that we did on Monday. We corrected it, and we started our new unit. Our new unit is about the Exploration of Space. To start this unit off, Ms.K read a sheet, " Why Explore Space?" . After that we watched a couple of videos of Kepler's three laws. We got the Chapter 8, Study Guide and we went over the first paragraph. We also picked up the sheet, Transparency 7-1. We answered questions on the back of the sheet.

Don't forget to get your Chapter 11 : Enrichment ; Energy in a Trebuchet in the folder.

Just to let you know, no school tomorrow.

Have a nice day off ~

Centripetal Force

Today, we did the lab on Centripetal Force. We got into groups and tested how long a rubber stopper would go around if we put 5 washers and so on. We will do this lab again, since we needed more time and also because some people were away.

Also a reminder that the worksheet we got yesterday, Centripetal Acceleration is due by Monday.

Momentum Lab

Today, we did a Momentum lab. The lab is from Chapter 9 (green text book). It was "The Explosion" lab. We had to calculate how far and fast the two carts went until they hit the bricks/books etc.

We had no time to finish it, due to the Pep Rally. I guess we will continue tomorrow with the lab.

Have a good evening, :D
