Extrasolar planet detection Put a coin in a balloon , spin the balloon and coin and throw them into the air. Observe the motion.
Scale Model of the Atmosphere Put two thicknesses of 2L PET bottle plastic on a 12 inch diameter globe to show the thickness of 90% of the atmosphere.
Atmosphere Bar A 5.5 foot long square steel bar 1 inch on a side weighs 14.7 pounds and exerts a force of 14.7 pounds per square inch, Atmospheric pressure.
Magnetic Atmosphere Model Stack 5 donut magnets on a pencil and observe atmospheric pressure.
Expansion of the Universe Draw a sine wave on a rubber band, pull the rubber band and notice how the wavelength increases. The same thing happens to light in a vacuum.
Spin a Kooshball Model the equatorial bulge of the earth.
