STEM Activities for Kids
Twenty things to do together that turn a kitchen table into a lab. Every one teaches a real idea in Science, Technology, Engineering or Math, and every one uses things a family already has or can easily find.

🧪 STEM Activities
Twenty hands-on activities, five each in Kitchen Chemistry, Forces & Motion, Build & Engineer, and Math & Patterns. Every one shows a picture of what you are aiming at, the materials, and the steps in order.
🔬 Think Like a Scientist
The same five-step pattern real scientists and engineers use every day: ask a question, guess an answer, test it, observe what happens, and draw a conclusion. Science is a loop, not a straight line.
Six of the twenty activities
🌋 Baking Soda Volcano (Kitchen Chemistry, Easy, 15 min)
Chemical reactions: mixing two things can make a brand new gas.
🌈 Rainbow Density Tower (Kitchen Chemistry, Medium, 20 min)
Density: some liquids are heavier for their size than others.
🥚 Egg Drop Challenge (Forces & Motion, Medium, 30 min)
Force and impact: padding changes how hard a landing hits.
🍡 Spaghetti & Marshmallow Tower (Build & Engineer, Medium, 25 min)
Structural engineering: why triangles hold shapes up better than squares.
🧭 Make a Floating Compass (Build & Engineer, Easy, 15 min)
Magnetism: turning a needle into a magnet that finds north.
🌻 Fibonacci Nature Hunt (Math & Patterns, Easy, 20 min)
Math patterns hiding in real plants.
Safe for families
Every activity that needs a grown-up's hands, heat, an oven, a needle, choosing a drop height, launching something, says so plainly right where it happens, not in a footnote. Nothing on the list needs an open flame, a corrosive chemical, or a power tool.
