KENTUCKY (8/10/17) Do you have a bean bag chair?

INGREDIENTS

  • Bicycle Pump with Rubber Stopper
  • 1 Liter Clear Plastic Bottle
  • Bean Bag Filler

INSTRUCTIONS
STEP 1:  Completely fill the clear plastic bottle with bean bag filler. Describe the bean bag filler by using its observable properties.     

STEP 2:  Attach the pump to the rubber stopper. Attach the rubber stopper to the clear plastic bottle.

STEP 3:  Pump the bicycle pump five times and observe. Remove the stopper and observe. Describe how the clear plastic bottle can be used as a model to describe how matter is made of particles too small to be seen.

EXPLANATION
Pumping air into the clear plastic bottle, increases the air pressure inside the bottle, squashing the bean bag filler. Once the rubber stopper is removed, the air rushes out, allowing the squashed bean bag filler to expand.
