Magic Balloon
We discovered that when you mix substances like vinegar and baking soda, you cause a chemical reaction.  The vinegar and baking soda “react” to each other and produce carbon dioxide.  This gas is what inflates the balloon.

Dancing Raisins
We discovered the raisins dance because bubbles like to stick on surfaces.  Carbonated drinks are filled with carbon dioxide bubbles that cling to the raisins and lift them to the surface.  When the bubbles burst, the raisins sink to the bottom. We also experimented with beans, lentils, corn kernels, and macaroni.

Monster Mud
Is it a solid or a liquid?  
Is it wet or dry?
We learned that when you suspend particles of one substance in another substance, you create a suspension!  Mixing a solid and a liquid together created a suspension.  Monster Mud acts like a liquid when you move it slowly.  It acts like a solid when you move it quickly.

Blobber & Slime
In these experiments we were working with polymers, tiny molecules in strands like a chain.  These polymer molecules can stretch and bend, which makes them special.  Jell-O, rubber bands, and gum are all forms of polymers.
