Simple Kitchen Science Experiments for Kids

Turn your kitchen into a chemistry lab with these simple science experiments! Get creative using minimal materials from your pantry.

Fizzing Colors

Kitchen Science Experiment: Fizzing Colors

Who says chemistry has to be complicated? You only need three ingredients for this experiment: baking soda, food coloring, and vinegar. When you combine the ingredients, a chemical reaction occurs and results in a bubbling eruption of fizzing color!

Magic Mug Cake

Magic Mug Cake: Science Activity

Normally, a cake would take an hour or more to make in an oven, but with a microwave oven, you can make one in minutes! Make this delicious chocolate mug cake and learn about the science of Microwaves ovens. Experiment with the other ingredients to customize your mug cake. What will you add to give it a whole new flavor?!

Turn Milk into Cheese

How to Make Cheese: Science Activity for Kids

You may remember hearing about curds and whey from the old nursery rhyme about Little Miss Muffet. Well, this kitchen science experiment will teach you what curds and whey are, and you’ll even make some yourself! You can eat cheese curds on their own (they taste like ricotta cheese) or top with honey or fruit for an awesome treat.

Hopping Grains

In this experiment, you’ll observe how carbon dioxide bubbles stick to the grains in the glass, lifting them up to the surface of the water. But when the bubbles reach the surface, they pop. Without the bubbles to hold them up any more, the grains sink back down to the bottom. Then the whole process repeats, giving you hopping grains in a cup!

Maple Syrup Crystals

Maple Syrup Science Activity for Kids

Test out the effects of temperature with this sweet science experiment! When you pour hot maple syrup onto a cold pan, sugar molecules slow down, combine, and then harden into solid crystals.The best part is, you can eat the crystals once you’re done with the experiment! Heads up: A grownup is needed to help operate the stove!

Apple Oxidation Experiment

Apple Oxidation Experiment for kids

Have you ever noticed that if you slice an apple in the morning, it turns brown by lunch? This is actually a chemical reaction at work! In this experiment, you’ll learn more about how the oxygen in the air around us causes this reaction (also known as oxidation). Test different liquids to see if you can figure out a way to keep apples fresh from morning to noon.

Frozen Color Mixing

Frozen Color Mixing Science Experiment

Experiment with color creation! Primary colors (red, blue, and yellow) are the source of all other colors. Secondary colors (green, purple, and orange) are created when two primary colors mix. If you freeze up colored ice cubes, you can experiment with color mixing as they melt.

Cabbage Chemistry

Color your world with cabbage and learn about chemistry! The terms acid and base describe chemical properties of many things we use everyday. Sometimes, you can tell if something is an acid or base by the way it tastes. Instead of a taste test, chemists use a pH scale to measure the strength of acids and bases. In this project, you’ll test different substances in purple cabbage juice and compare the results to a printable pH scale.

  1. These are great ideas for experiments. I can’t wait to try them with my son.
    We love Kiwi crates!!
    Thank you.

  2. what a wonderful idea, Kiwi! thank you for your creativity, your thoughtfulness regarding at home kids, and your continued efforts too bring science and crafts to my grandchildren

  3. I think the Juicy Gel Bubbles experiment may need some tweaking. We followed the instructions exactly (1 cup juice, 1 teaspoon agar) but our bubbles were solid gel all the way through…so we ended up with a bunch of oily globs of jello.

  4. Good old vinegar and bi carb! Works every time. Maddy loved the fizzy colours. She worked out that blue and yellow made green and red and yellow made orange. Kept on mixing until she had a big dark fizzy mess, then I put it down the sink to help clear the drains. Couldn’t be better.
