So how does one get started doing science labs with kids in the kitchen? The best way is to start by letting kids explore with their food. Have them make observations and talk about items in the kitchen. Cut open various foods to explore them, inside and out. Use a magnifying glass or microscope to examine items up close. Invite them to help you bake and cook. Let them see up close the transformations food can undergo in the kitchen. Let them get hands on and explore. It’s amazing the amount of learning that can happen when we let kids follow their interests.

Once you are ready to start some more structured lessons, here are some genius kitchen science lab activities for kids. Let these inspire your own kitchen science experiments!
