Simple Kitchen Science Experiments for Kids

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

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

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 microwave 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

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

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

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

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. 

Juicy Gel Bubbles

Make fruity gel bubbles that pop in your mouth! The magic ingredient is agar powder. Agar powder is a gelling agent that comes from a type of algae. Make multiple batches in different colors! 

Rock Candy

Did you know you can grow your own sugar crystals at home? In this experiment, you’ll learn about crystal growing science while making edible sweet treats.  

Cabbage Chemistry

Color your world with cabbage and learn about chemistry! The terms acid and base describe the chemical properties of many things we use every day. 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.
