Thursday 14 January lesson

Hello everyone!

Here there is the scribe post of the lesson of today, 14-01-2010. Today first Ms. D. checked our homework, which was finishing the graph of acceleration and deceleration of the ping pong ball using the document that we have shared on Google Docs. After this, we watched three videos of Bill Nye the science guy about friction, and I think it was very helpfull.

Here you can find them:

http://www.youtube.com/watch?v=mKWVcZ5yHfo&feature=related (Bill Nye friction 3/3)

After we have watched the videos, we read pages 42-45 on our Science Explorer textbook; then Ms. D. explained us the meaning of these pages, and we took notes. Also, like last time, Viktor, Noam , and Reza took notes on the small laptops, on Google Docs.

Here there are the links:

I would remind you that tomorrow there is some homework!

Random Questions:

1. Where is the Marians Trench? What Ocean? How deep is it?

2. What is the capital of Bolivia?

and reading pages 42-45 of the Science Explorer textbook.

Ms. D. also reminded us the gravity, here's a picture that may can help:

The two arrows going down

say "Air pressure" and

"Gravity". The arrow going up says " Force of the floor"and the thing in the middle of the square says "Box".

That's it, the next scribe is Iva.
