minutes - using a sheet of (used) paper.
Electricity Projects Make flashlights electric switches! Uses inexpensive materials like paper clips
and holiday twinkle lights.
Polymer Slime Use in conjuction with the next project for a full hour of science - start off by giving the kids gummy
worms and talking about properties of polymers. Click HERE for a polymer game.
Fake Blood Make a simple mixture that looks like real blood.
Hovercraft Build one for the kids to ride! External link.
Soap Science Use Chemistry to make real soap! This method is easy and hands
on - each kid makes his own batch!
World's Simplest (and cheapest) Motor (external link, you can probably get plenty of wire scraps free from shops that build electric
motors and generators. Follow the instructions carefully in the fifth photo and substitute sand paper for the knife
-easier for kids.) A video of another motor and how it works HERE. A similar motor HERE.
Soda Pop Science (Three awesome projects from those "Better Living through Chemistry" people. Follow these up with a Mentos Fountain: Tell the kids to bring their own unopened 2 liter bottle of diet soda for the fountains (that way
you don't have to transport them.)
