KENTUCKY (9/28/2017) Leakproof bag.

INGREDIENTS

  • Several Round Sharp Pencils
  • Water
  • Re-sealable Storage Bag


INSTRUCTIONS

STEP 1:  Fill the re-sealable storage bag with water. Describe the re-sealable storage bag by its observable properties.    
STEP 2:  Gently push the round sharp pencils through the bag. What happens? Describe how pushing round sharp pencils can be used as a model to describe how matter is made up of particles too small to be seen.  

EXPLANATION
The bag is made of polymers. Polymers are long, repeating chains of molecules and when the sharp pencil is pushed through the bag, these chains of molecules seal up around the pencil, preventing the water from leaking out of the bag.
