Special properties of spinning objects -  gyroscopes, balls, rotors, wheels, the planet Earth.  The motion of spinning objects are affected by friction.	Carbon Dioxide is a colorless, odorless gas used in many consumer products - Alka Seltzer film canister rocket/ coke/mentos experiment.	The Morse Code Telegraph is based on the electromagnet.   Magnetism is a natural force in nature, gravity is also a natural force that pulls objects toward the earth.
Sir Issac Newton's Third Laws is known simply as Action / Reaction & can be demonstrated with a balloon helicopter & film canister Alka Seltzer / water rocket.		Bernoulli Effect - as the velocity of a fluid increases, its pressure decreases - both cool demo's by Jeff & three cool class experiments with everyday material.
PV Cells (solar panels) transform solar energy into electrical energy. Electricity requires a complete path (circuit) to flow.	Some chemical reactions are fast, some are slow. Some substances can bond with water, some cannot .	The three basic subatomic particles are protons, neutrons, and electrons. A molecule is the smallest unit of a substance that shows all the properties of that substance. Polymers are made of strings of molecules & occur naturally and are also man made.
