A gift for our friends...pt 2

Step 1: Open up the paper tubes

On Thursday, we attenplted to make the bouncy balls.  Unfortunately, they ended up looking like flat pancakes!  We decided to focus our efforts on the marble run instead.

This week Earth Groups marble run gift to the class helped us learn about how gravity affects the speed of an object.  WHY DOES THE MARBLE FALL?  Marbles do not move very quickly when the marble run is horizontal.  The higher the angle, the faster the marbles went.  We learned that when objects travel down an incline plane (like the marble run) gravity pulls them and the marble run (the plane) exerts a force on the marble (object) which makes it fall.
