Have a blast with this gas-powered flyer!
These rockets enable students to use design thinking and are effective demonstrations of Newton’s laws of motion. The liftoff power of the rocket is produced by a common acid/base chemical reaction that creates carbon dioxide gas; making this activity an ..
A “Note”worthy Sound Activity
Build a Glove-a-Phone to discover how a plastic glove, straw and tube can be combined to make a "musical" instrument. Once you learn the proper technique, your Glove-a-Phone can be heard a surprisingly long way off! Use different size tubes and compare the sounds.

Get wound up with wind power!
Use this enhanced pinwheel to measure the mechanical energy that can be obtained from moving air. Make the pinwheel spin by holding the device while walking or by using the "wind" from a fan. Take data - including measuring how much time is required for the device to..
