There are many benefits to having preschoolers participate in some fun and engaging science activities. It helps them develop their problem-solving skills, critical thinking skills, and an overall love of learning. As they become more familiar with the scientific process and how it works, they will be able to take this knowledge with them well into their future as students.
As a parent or caregiver, you have the opportunity to be your child’s first and most important science teacher! The following fun and creative science activities for preschoolers are sure to delight and educate your little scientist.
This is a wonderful collection of free preschool science activities from a variety of blogs that I know you will enjoy. There are lots of fun ideas here that would be great to try at home or in your classroom.
Exploring Color Mixing with Preschoolers – This is such a simple but exciting activity for young children. It’s never too early to explore color mixing, and this activity can easily be adapted for children of all ages.

How to Make Your Own Bubble Solution – This is one of my favorite preschool science activities because it’s so easy to set up and kids love it! You don’t need any expensive materials either, just dish soap and water.

Water Bottle Rockets – Talk about STEAM activities with this awesome idea from Little Bins for Little Hands. This is a great activity if you have older kids at home who can help make their own rockets.

Sink or Float Experiment – This is a classic preschool science experiment that will help kids learn about the properties. Use objects from around the house to see what sinks and what floats. Ask your child why they think some objects sink and others float. Talk about how many objects are made of different materials and that makes them behave differently in water. Use this as an opportunity to talk about density, mass, buoyancy, and other science concepts.

Blow Up Balloons With Vinegar and Baking Soda

This is a great activity if you want to show your child how chemical reactions work. It’s also a chance to talk about the physical changes that occur when vinegar and baking soda mix together, creating carbon dioxide gas. You can talk about how the balloons blow up because of pressure created by the gas. To do this experiment, put equal parts vinegar and baking soda in a plastic bottle and attach the balloon over the top of it so that no air can escape.
Try an experiment with baking soda and vinegar: put a little bit of both into a plastic cup and watch what happens when you mix them together! If you want to take things further, try putting some food coloring in with the ingredients, or adding dish soap for even more bubbling action.
You’ll need sunlight for this next activity: try making a rainbow with a clear glass of water and a prism (or anything else that has a lot of different-colored surfaces). Shine the light through one side and see how many colors come out on the other side! Or put some water into an ice cube tray, add food coloring to each compartment

Make an invisible ink message. Get a glass of water, squeeze in some lemon juice, dip a q-tip into it, then write on white paper with the q-tip. Your child will be amazed when you use a flashlight to “reveal” their message.
Make your own lava lamp using vegetable oil and water, food coloring, and an alka-seltzer tablet. This one is really fun if you have plastic bottles lying around.
Grow your own crystals by mixing borax powder with boiling water and letting it cool overnight before adding pipe cleaners or string for your child to hold onto while you pour in the borax solution.
