Seatbelt and Newton's 1st Law

This week we'll try to demonstrate Newton's 1st law as it relates to wearing seat belts. We were able to shoot video of  a basketball moving forward as it was thrown out of a moving car.

Air For Sale

Logic and the Pig-pile Below Everest!

This week, we continue building  a density column with liquids and solids and hopefully find the mass of air. Yes that's right, air. We'll discuss climbing Everest and ultimately ending up in a pig-pile. But in order to understand, we'll need to think through some logic. Click the link below.

Density Column

This week students will be building a Density Column after calculating the density of different liquids and making hypotheses to the position of each. Students will also add a few solids and while I'm typing this, I just thought we should inject a few gases also. Why not right? What could happen?
