Makes Kids Curious

When kids mix things like baking soda, vinegar, milk, and food coloring that they see every day, they start asking questions. They wonder why these things act the way they do when mixed. Seeing the colorful changes keeps them interested and wanting to learn more.

Helps Learn Science Basics

Doing these experiments, kids get to guess what will happen, watch what actually happens, and think about why it happened. This is a great way for them to start learning how to think like scientists, ask questions, and solve problems.

Improves Hand Skills

Doing things with their hands, like pouring, mixing, and stirring, helps kids get better at using their fingers and hands. This is important for when they start learning to write.

Fun Family Time

Doing science in the kitchen is a great way for families to have fun together. It makes learning interesting and helps kids see how fun science can be. Plus, it's really special to see your kid light up when they see what happens in these experiments.

Safety First

Keeping everyone safe is the most important thing when you're doing kitchen science with preschoolers. Here's how to make sure everything goes smoothly and safely:

Adult Supervision

  • Always have an adult around to watch over the kitchen science fun.
  • Go through simple safety rules with the kids before you start.
  • Stay alert so you can help out or clean up any spills right away.

No Eating or Drinking

  • Make sure kids know not to eat or drink anything from the experiments unless an adult says it's okay.
  • Some stuff we use, like baking soda and vinegar, isn't safe to eat on its own.
  • Always check with an adult before tasting anything from the experiments.

Protect Clothes and Surfaces

  • Put on old clothes or aprons to keep clean in case of spills.
  • Use newspapers or plastic covers to protect tables, or just do the experiments in the sink.
  • Clean up any messes right away to keep things neat.

Use Child-Safe Items

  • Use blunt knives for cutting, not sharp ones.
  • Give the kids plastic bowls and spoons instead of glass or ceramic.
  • Be careful with anything that could break, like thermometers.

Wash Hands Afterwards

  • Always wash hands with soap and water after doing experiments.
  • Clean all the surfaces you used well.
  • Throw away any leftover materials from the experiments the right way.

By getting ready and keeping an eye on things, kitchen science can be a safe and fun way for kids to learn and explore. Just remember these simple safety tips to make sure everyone has a good time.

Kitchen Stuff for Easy Experiments

You can find a bunch of everyday items in your kitchen that are perfect for simple science fun with little ones. Here's a list of things that are safe and easy to use for experiments.

Baking Soda

Baking soda is something you probably have in your kitchen. It's awesome for experiments because it bubbles up when mixed with vinegar, which is really fun for kids to watch.

White Vinegar

White vinegar is another must-have for kitchen science. It reacts with baking soda to make fizzing bubbles, which is super exciting for preschoolers to see.

Vegetable Oil

Vegetable oil is great for showing how some liquids don't mix together. If you pour it into water, it floats on top because they don't mix.


Mixing cornstarch with water makes a weird goo that feels like a liquid when you pour it but feels solid if you squeeze it. Kids find this really cool.

Citrus Fruits

Lemons, limes, and oranges have acid in them that can make interesting reactions happen. They can also change how some colors look.


Milk is good for showing what happens when you mix it with something acidic like vinegar or lemon juice. It splits into chunky bits and liquid.

Liquid Food Coloring

Just a few drops of food coloring can make experiments look amazing and colorful. It's safe for kids, so no worries there.

Dish Soap

A little bit of dish soap can make big bubbles or make fizzy drinks overflow. It works by changing the way water sticks together.

With these simple items from your kitchen, you're all set to start doing some really cool, safe science experiments that are perfect for little kids.## Dancing Raisins Experiment

Materials Needed

For this experiment, you'll need:

  • A clear glass or jar
  • Fizzy water or soda
  • 5-10 raisins

Use a clear glass so you can see everything happening. Sparkling water, soda, or any fizzy drink is perfect for this.


Follow these easy steps:

  • Fill the glass halfway with your fizzy drink.
  • Gently drop in 5-10 raisins.
  • Watch as the raisins start to move up and down in the glass.

You'll see the raisins go up and down because of the tiny bubbles that stick to them. These bubbles make the raisins light enough to float to the top. When the bubbles pop at the top, the raisins sink back down. Then, it starts all over again!

The Science Behind It

Here's why the raisins move:

  • Fizzy drinks have a gas called carbon dioxide (CO2) mixed in.
  • When you put raisins in the drink, CO2 bubbles stick to their rough surfaces.
  • These bubbles make the raisins lighter than the drink, so they float up.
  • At the top, the bubbles pop, and the raisins get heavier and sink.
  • Then, new bubbles form, and they float up again.

This up and down movement is why we say the raisins "dance." If you try other dried fruits or things with rough surfaces, you might see them dance too!

This simple experiment is a fun way to show how bubbles can make things move in water. It's a cool kitchen science trick that's easy and safe for kids to try at home.

Magic Milk Experiment


For the Magic Milk experiment, you'll need:

  • A bit of whole milk (it works better than other kinds)
  • Cotton swabs
  • Different colors of liquid food coloring like red, yellow, green, blue
  • A little bit of liquid dish soap
  • Pie plates or shallow bowls to do the experiment in


Here's how to do it step by step:

  • Pour a thin layer of milk into the pie plates or bowls.
  • Drop a bit of each food coloring into the milk, keeping each color in its own little spot.
  • Dip the tip of a cotton swab into the dish soap, then gently touch it to the food coloring in the milk.
  • Watch as the colors spread out and make cool swirls!

Just a small touch of dish soap is all you need. If you use too much, you'll have a milky mess!

The Science

Let's break down what's happening:

  • Milk has something called casein in it, which usually sticks to the milk's fat.
  • Adding dish soap messes up the stickiness between the casein and fat.
  • Once the casein is free, it grabs the food coloring and spreads it all through the milk.
  • This makes the awesome swirling colors you see.

This experiment is a fun way to show how mixing things up can create something totally new and exciting. Plus, it's a cool visual that's easy and safe for kids to try at home.## Fizzy Lemonade Experiment


To make fizzy lemonade, you'll need:

  • 1 cup water
  • 1/4 cup lemon juice
  • 1 teaspoon baking soda
  • Spoon
  • Cup or glass


Here's what to do:

  • Start by pouring 1/4 cup of lemon juice into your cup. Lemon juice is sour because it has citric acid.
  • Next, add 1 teaspoon of baking soda and mix well. Baking soda is a base, which is the opposite of an acid.
  • Then, pour in 1 cup of water and stir everything quickly. You'll see it start to fizz and bubble!
  • Now, you can drink and enjoy your fizzy lemonade!

The Science

Let's talk about why it bubbles:

  • Baking soda is a base, which means it can take in protons.
  • Lemon juice is an acid because it has citric acid that gives away protons.
  • When you mix baking soda with lemon juice, the citric acid gives its protons to the baking soda in a reaction.
  • This reaction makes carbon dioxide gas, which is what causes the bubbles and fizzing.
  • These bubbles make the lemonade fun and fizzy!

This easy experiment is a cool way to see a chemical reaction happen. It's a simple, safe way to make a tasty fizzy drink using things you probably have in your kitchen.


Invisible Ink Experiment


To try this cool trick, you'll need:

  • A lemon
  • A cotton swab or paintbrush
  • White paper
  • Something warm like a lightbulb or oven


Here's how to make your own secret messages:

  • Dip the cotton swab in lemon juice and write a message on the paper.
  • Let the lemon juice dry. Your message will disappear!
  • To see the message again, warm up the paper near something hot. A light bulb is perfect for this. Watch as your message shows up!
  • If the message fades, just heat it up again to show it to someone.

The Science

Let's talk about why this works:

  • Lemon juice has a special part in it called limonene.
  • When limonene touches air, it changes and becomes something you can't see when it's cold.
  • But when you heat it up, it turns brown and you can see it.
  • Heating makes the limonene get excited and change so we can see the message.

It's a super cool way to send hidden notes with a bit of science magic! The acid in the lemon is what makes the message show up when it gets hot.

Understanding the Scientific Method

The scientific method is a way scientists figure out how things work. It's like being a detective, but for science. Here's a kid-friendly way to do it:

Make a Prediction

  • Think about something you want to try, like mixing stuff together.
  • Guess what you think will happen. This guess is called a "prediction."
  • Kids can make simple guesses like "I think it will turn blue" or "It will bubble up."

Try Your Experiment

  • Go ahead and mix things or do your test.
  • Watch carefully to see what happens.

Talk About What Happened

  • See if what you thought would happen did happen. If not, that's totally fine!
  • It's all part of learning. Even a wrong guess teaches us something.
  • Chat about why things turned out the way they did.
  • Was there anything unexpected? What did you notice?

By doing these steps, preschoolers learn to:

  • Guess and check their guesses.
  • Understand that being wrong is just another way to learn.
  • Begin thinking like scientists by asking "why?"
  • Build skills in solving problems and thinking critically.

Doing simple experiments and talking about what you see is a great way to get the hang of scientific thinking. It turns science into a fun game and shows kids how we use science to understand the world!## Ideas for a Kitchen Science Fair

Having a kitchen science fair is a great way for kids to show off what they've learned from doing experiments. Here are some simple ways to take those experiments further and create a fun science fair for family and friends:

Record Observations

  • Kids can draw pictures of what they saw happen in each experiment.
  • They can write down what they saw in their own words.
  • Use a thermometer to see if anything gets hotter or colder.
  • Measure how far or high things go.

Graph Results

  • Use coloring blocks to make easy bar graphs for each test.
  • Use markers to draw lines that show how things changed over time.
  • With a little help, kids can label parts of the graph like the x and y axes.

Repeat Experiments

  • Do the experiments more than once.
  • Check if the same thing happens every time.
  • Try to be as accurate as possible with how much you use or measure.

Change Variables

  • Change one thing at a time, like how warm it is or how much of something you use.
  • See how this one change makes things different.

Make Predictions

  • Have kids guess what they think will happen before they start.
  • See if what actually happens is what they thought would happen.

Come Up with New Tests

  • Think of new things to mix or try.
  • Encourage them to come up with their own experiment ideas.

Make Posters to Show Results

  • Put drawings, graphs, photos, and descriptions on a poster.
  • Add titles and let kids explain their work.

This science fair is a chance for kids to practice explaining their science discoveries just like real scientists. Even simple things like drawing what they saw can help preschoolers get ready to talk about their science experiments!
