In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures. Both homogeneous (whole thing looks the same) and heterogeneous (looks different in different sections) mixtures are created. Static electricity is used to separate salt from pepper. Soap is used to make oil and water mix. Baking powder (an inhomogeneous mixture) is mixed with water to produce a gas. The activity was designed as a kit that could be checked out of a library, but can be done without the kit.
