In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).
