Fun Science Experiments for Preschoolers

Science experiments for preschoolers are a fantastic way to introduce young children to the wonders of the natural world while engaging their curiosity and developing their critical thinking skills. These fun and simple experiments spark creativity, help preschoolers understand cause and effect, and allow them to observe scientific concepts in action. Whether it’s mixing colors, watching a balloon inflate, or making slime, science activities provide hands-on learning experiences that are both educational and entertaining. These activities also encourage children to ask questions, explore materials, and think like little scientists, all while having a blast!

COLORFUL MIXING MAGIC
‍
One of the simplest and most exciting science experiments for preschoolers is mixing colors. You can introduce children to the concept of color theory by mixing primary colors—red, yellow, and blue—to create secondary colors—orange, green, and purple. Using clear cups or bowls, fill them with water and add a few drops of food coloring. Then, give the children pipettes or small spoons to transfer and mix the colors. As they experiment with different combinations, they’ll be fascinated by the changes in color. This activity also helps preschoolers develop fine motor skills as they handle the pipettes and explore the effects of mixing. It's a fun and visual way to teach them about the science behind colors!

BALLOON INFLATION SCIENCE
‍
Another exciting science experiment involves inflating a balloon using baking soda and vinegar. This experiment teaches preschoolers about chemical reactions in a fun and safe way. Fill a plastic bottle with vinegar and attach a balloon that’s filled with a few tablespoons of baking soda (you can use a funnel to make this easier). Once the balloon is attached to the bottle, let the children watch as the baking soda and vinegar react, causing the balloon to inflate. The children will be amazed at the fizzy reaction and will start to understand the concept of how some substances can cause changes in other materials. It’s a great example of a simple experiment with a big wow factor!

SLIME TIME!
‍
Making slime is always a favorite activity for preschoolers, and it’s a fantastic way to explore scientific properties like texture, viscosity, and chemical reactions. To make slime, combine a cup of white glue with a tablespoon of baking soda, and then add a few drops of contact lens solution. Mix everything together and watch as it transforms into a squishy, stretchy slime! You can even add food coloring or glitter for added fun. As preschoolers squish and stretch the slime, they’ll learn about the properties of materials and how substances can change forms. This hands-on experiment also allows children to explore textures and engage in sensory play, which is an important part of early childhood development.

MAGIC MILK EXPERIMENT
‍
The magic milk experiment is a visually captivating way to teach preschoolers about surface tension and how different substances interact. To do this experiment, fill a shallow bowl with milk, then add a few drops of different food coloring around the edges of the bowl. Dip a cotton swab into dish soap, and then touch the soap-covered swab to the center of the milk. Watch as the colors swirl and move in fascinating patterns! This happens because the dish soap reduces the surface tension of the milk, causing the colors to spread. Preschoolers will be mesmerized by the movement of the colors and will begin to understand how substances can interact with each other in surprising ways.

FLOAT OR SINK?
‍
The float or sink experiment is a simple yet exciting way to introduce preschoolers to the concept of buoyancy. Fill a large container with water and gather various objects like a spoon, a rock, a rubber duck, and a piece of paper. Ask the children to predict whether each item will float or sink. Then, one by one, drop the objects into the water and observe what happens. Afterward, discuss why some objects float while others sink. This experiment helps children understand the scientific principle of density and encourages them to think critically about the properties of different materials.
