In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.
