Chicken Sounds From a Plastic Cup -- we decorate the cups with red felt combs and plastic eyes, and use cotton string and a piece of sponge instead of yarn and paper towel....so much fun!

Cartesian Diver to teach about buoyancy and density. I like making them out of a cut pipette and a nut because you can see the water level get higher when it is pressurized (thus making it more dense and making it sink.) Some of the other closed system divers are harder to observe getting more dense under pressure because they are just being squished and that is hard to see.

Build a paper rocket and send it flying with a single puff of air. Discover how various fins can change how your rocket will fly...  Rocket is made by wrapping paper around a pencil, taping it, removing the pencil, and adding paper fins.  The launcher is a straw that you blow through.

In the "Building a Simple Motor Puts a New Spin on Magnets" electricity and electronics #science project, students build a simple Beakman motor and investigate how design changes affect the rate and direction of rotation. A project kit of specialty items is available to do this science project!
