Here’s a fun lesson plan for Halloween that demonstrates diffusion and the properties of stretchy polymers.
Target Grades: 3-5
Subjects: Chemistry, Physical Science
Duration: 30 minutes for setup and activity
Game objective: Partygoers will try to guess the mystery smells coming from within a series of inflated Halloween bats.
Learning objective: Partygoers will explain and demonstrate how the stretchy molecules of the inflated bats have enough space between them to allow smaller, more concentrated molecules, to pass between them.
