20 Science Project Ideas for Young Kids

Aside from reading books to learn about different things, doing hands-on activities is another effective way of teaching young children especially about Science. It is also a good bonding activity for you and your kids during the weekends compared to just watching movies and playing video games. If you want your young kids to learn more about Science, here are some wonderful science project ideas you can try with them.

Blow Up Balloons with CO2

With this activity, you’ll be able to teach your kids about chemical reactions. This experiment will make use of the carbon dioxide given off by a baking soda and lemon juice reaction by funneling the gas through a soda bottle and into the balloon. Materials Needed:

  • Balloon
  • 40ml of water
  • Soda bottle
  • Drinking straw
  • Lemon juice or vinegar
  • 1 teaspoon of baking soda

First, pour the 40ml of water into the soda bottle. Then add the teaspoon of baking soda and stir it around using the straw until it dissolves. After that, pour the lemon juice in and quickly put the stretched balloon over the mouth of the bottle. If the experiment is successful, the balloon should inflate.

Make Water Float

You don’t have to be a wizard or a witch to make water float. In this experiment, kids will learn about air pressure. The only materials you need is a small glass of water and a sink where you’ll conduct the experiment. Check out Red Tricycle’s blog to find out how to make water float.

Escaping Water

In this science project, you and your kids will be able to see that water can certainly move in mysterious ways. Materials Needed:

  • One glass of water
  • An empty glass
  • Some paper towels

First, twist a couple of paper towel together until you form something that looks like a rope. This will stand as the wick that will absorb and transfer the water. After that, place one end of the paper towels into the glass filled with water and the other end should go into the empty glass. Finally, watch what will happen. This process is called capillary action. It can be seen in plants where moisture travels from the roots to the rest of the plant.

Create a Film Canister Rocket

This project is all about rocket science. If your kids have tried the baking soda and vinegar experiments, this one will take that to the next level. The things you need are, plastic bottle with a snap top, water, and Alka-Seltzer tablets. To see the full detailed instructions on how to create the film canister rocket, check it here.

Design and Test a Parachute

This science project will teach your kids about air resistance. Materials Needed:

  • A plastic bag
  • Scissors
  • String
  • A small object to as the weight (small action figure)

First, cut out a large square from the plastic bag then trip its edges so it would look like an octagon. After that, cut a small hole near the edge of each side. Attach eight pieces of string with the same length to each of the holes. Then, tie the pieces of string to the action figure. Finally, find a high spot where you’d drop the parachute and test how well it will work. Drop it as slow as possible. The larger the surface area, the slower the parachute will drop because there is more air resistance.

Potato Power

This experiment is all about chemical to electrical energy. Do you believe potatoes can be used as batteries for your devices? They certainly can! Find out how by checking out PBS Kids tutorial.

Water Density Rainbow

This experiment will teach kids about water density. Materials Needed:

  • Food coloring
  • Tablespoon
  • Five clear glasses or plastic cups
  • Water

You will be able to create different density levels by adding more or less sugar to each water solution. The food coloring will help you determine which solution is the heaviest. You can also add the colors in a rainbow order to amaze the kids.

Create Cloud Jars

This science project will show how clouds hold water. All you need is a jar, shaving cream, food coloring, and water. Do you want to know how to do this weather experiment? See the full detailed instructions here.

Make a Big Dry Ice Bubble

Kids will love this experiment but adult supervision is needed when handling dry ice as it can cause skin damage if not used safely. Materials Needed:

  • Water
  • A large bowl
  • A strip of cloth
  • Soapy mixture
  • Dry ice

First, place the dry ice into the bowl and add some water. Then soak the cloth in the soapy mixture and run it around the lip of the bowl before dragging it across the top of the bowl to form a bubble layer over the dry ice. Finally, stand back and watch the bubble grow. The process of dry ice changing from solid to gas is called sublimation. This process creates clouds of fog that fill up the dry ice bubble.

Bend Water Using a Comb

This experiment will teach your kids about electrical currents. The only materials you need is a comb and a faucet with running water. Comb your hair several times then bring the comb towards the water. The electricity you generated with the plastic comb and your hair should cause the water to bend toward the comb. It might not work at first but try a couple of times.

Create Invisible Ink with Lemon Juice

Kids will have fun using invisible ink to write secret codes while they pretend to be secret agents. Materials Needed:

  • Half lemon
  • Water
  • Spoon
  • Bowl
  • Cotton bud
  • White paper
  • lamp

First, squeeze the lemon juice into the bowl and add a few drops of water. Then, mix the water and lemon juice with spoon. Dip the cotton bud into the mixture and write a message onto the white paper. Wait for it to dry so it becomes completely invisible. When you want your message to be read, heat the paper using a lamp or a light bulb. Make Tensile Bubbles This experiment will let the kids make cubic bubbles. The things needed are straight straws, pipe cleaners, bubble solution, and a tall Tupperware container. You can check out the detailed instructions here. Make a Paperclip Float This experiment will teach kids all about surface tension Materials Needed:

  • Clean dry paper clips
  • Tissue paper
  • A bowl of water
  • Pencil with eraser

First, try to make the paper clip float in a bowl full of water. You will see that it won’t. You’ll need to tear a piece of tissue paper and gently drop it flat onto the surface of the water. Then, place a dry paper clip flat onto the tissue gently without touching the water or the tissue. After that, use the eraser of the pencil to poke the tissue until it sinks. If the experiment is successful, the tissue will sink and the paper clip will float. These are just some of the many science projects young kids can make. We hope you and your kids will enjoy and learn from these science activities.
