Materials needed
Oil Spot Photometer
Blank white index cards (4x6 are best but any size will work.) One per teacher.
Cooking oil (a small supply to wet the center of the cards)
a meter stick (one for each group)
lightbulbs One incandescent perhaps 60 watt, one compact fluorescent 60W equivalent, optional one LED 60 W equivalent.)
Lightbulb holders (clamp lights, light bulb bases)( 2 per group)
150 watt lightbulb (or 200 W) one total to measure the power of the sun)
Extension cord to run light outdoors.
Self Centered Globe
Earth globe 9 inches diameter or larger (One per group)
Small earth globe 4 inches or smaller (One per group)
Cylinder 4 inches in diameter 4 inches high (place the globe on the cylinder)
Domino Model of a Nerve
Meter stick (one per teacher, or piece of wood as stiff as a wooden meter stick I got about 1/4" thick and 1" wide and at least 18 inches long)
Blank Plastic Dominoes http://bulkdominoes.com/products/mixed-colors-dominoes $13 per 100, 20 per teacher
Masking tape 1 3/4 inch wide roll per group
Stopwatch 1 per group (Micron Timer)
Pendulums
String
Washers as weights
optional extras
