In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
