At Playful Chef, we believe learning happens best when kids get to taste the science! In this colorful collection of edible experiments, your little chef will mix and fizz their way through fun kitchen reactions that double as delicious treats.

These hands-on activities are perfect for ages 5–6, with simple instructions, everyday ingredients, and plenty of learning baked right in. Before you get started, download our Experiment Observation Sheet to get the most out of your experience! Let’s cook up some science!

Fizzing Lemonade Potion
Ages 5–6

What You’ll Need:

Ingredients:

  • 2 tablespoons fresh lemon juice (about ½ lemon)
  • 1 teaspoon sugar (optional for taste)
  • ¼ teaspoon baking soda
  • ¼ cup cold water

How To:

  1. In a clear cup, mix the lemon juice, sugar, and water.
  2. Stir gently to dissolve the sugar.
  3. Let your young chef slowly sprinkle in the baking soda and watch it fizz!
  4. Stir and sip — the potion will be slightly fizzy and tangy.

What Makes the Fizz?

When you mix lemon juice (which is acidic) with baking soda (a base), you get a chemical reaction. This reaction produces a gas called carbon dioxide (CO₂) — the same kind of gas that puts the fizz in soda and makes bubbles in cake batter!

Here’s how it works:

  • Lemon juice contains a natural acid called citric acid.
  • Baking soda is a base called sodium bicarbonate.
  • When they meet in water, they start to bubble and fizz because they are reacting with each other.
  • The gas that forms — carbon dioxide — escapes as bubbles and makes the mixture frothy and fizzy!

This is an example of an acid-base reaction, and it’s safe and fun to observe in the kitchen.

Science Vocabulary:

  • Acid – A sour-tasting ingredient (like lemon juice or vinegar).
  • Base – A bitter-tasting, powdery ingredient (like baking soda).
  • Chemical reaction – When two ingredients change each other and make something new (like fizz!).
  • Carbon dioxide – A gas that forms bubbles in fizzy drinks and baked goods.

Want more fizz?

Try adding more baking soda, then less. Which one fizzes faster?

Use a tray under the cup to catch any fizz overflow & taste test the balance of sour and sweet — kids can adjust sugar to their liking.


Dancing Raisins Soda Show
Ages 5–6

What You’ll Need:

  • Clear soda (club soda or lemon-lime)
  • A few raisins
  • Clear cup

How To:

  1. Drop raisins into soda.
  2. Watch them rise and fall like tiny scuba divers!

Why Do the Raisins Dance?

Raisins don’t normally float. But in bubbly soda, they put on a dancing show! That’s because carbon dioxide gas in the soda creates bubbles that lift the raisins up — and when those bubbles pop, the raisins sink back down.

Let’s break it down:

  • Soda is filled with carbon dioxide gas, which makes tiny bubbles.
  • When you drop raisins into the soda, bubbles stick to the wrinkly surface of each raisin.
  • As more bubbles stick to the raisin, they act like little balloons, lifting the raisin upward.
  • When the bubbles pop at the surface, the raisin gets heavier again and sinks.

This up-and-down movement continues until the soda loses its fizz — or the raisins get too soggy to bounce back.

Science Vocabulary:

  • Carbonation – The gas bubbles in soda that make it fizzy.
  • Buoyancy – How well something floats or sinks in a liquid.
  • Density – How heavy something is compared to how much space it takes up.
  • Surface tension – The skin-like layer on top of the soda that helps hold the bubbles together.

Try the same experiment with a dry cranberry or a piece of pasta. Do they dance too?

Great for a calm, seated activity—no mess!
