[YAPA] microgravity demonstrations of forces and motions in your classroom

[Rich DeLombard]

YAPA Teachers,

You can combine microgravity (aka weightless) concepts with your  
forces and motion lessons with the use of a Microgravity Demonstration  
Kit and/or a Drop Tower for educators.  The demo kit helps to explain  
why the space station orbits the Earth, why it is NOT zero-gravity up  
there, how planets orbit the sun, and more. The drop tower allows your  
students to see the effects of "removing" gravity from a system.  
Students can then make their own demonstration devices to investigate  
gravity and forces and motion.

This page describes these two sets of equipment that can bring  
microgravity into your classroom.

Why just explain the solar system in terms of relatives sizes of  
planets separate from their separation distances?  Why not have your  
class make a scale solar system by combining those two size concepts?   
This can be done with scale planets and Sun within 600 meters.  Check  
that web page for more info.
