STEM experiments for kids are one of the best ways to make learning fun, interactive, and memorable. By combining science, technology, engineering, and math, STEM activities help children explore the world around them through hands-on discovery.
The best part? Many STEM experiments can be done at home or in the classroom using simple, everyday materials—no fancy equipment needed.
What Is STEM Learning for Kids?
STEM stands for:
Science – Exploring how things work
Technology – Using tools and problem-solving skills
Engineering – Building, testing, and improving ideas
Math – Counting, measuring, and analyzing
STEM experiments encourage kids to ask questions, test ideas, and learn through play.
Dancing Lentils
Watch lentils “dance” in liquid during this exciting science activity. Kids learn about Chemical reactions, Movement and observation, Early STEM concepts. Get tutorial here.
Fireworks In a jar
This experiment is a great way to introduce kids to the concept of density and solubility. Oil is less dense than water and doesn’t mix with it, which is why it floats. Food coloring, on the other hand, is water-based and denser than oil, so once it breaks free, it sinks through the oil and disperses in the water, creating beautiful bursts—just like fireworks!

Baking soda and Ballon experiment
Kids learn about Chemical reactions, States of matter (gas production), Cause and effect, Science safety and observation skills. Get tutorial here.
Oobleck experiment
This experiment teaches kids about states of matter and fluid behavior.Check tutorial here.
Blooming flowers
Growing star
Lava Lamp
Fizzy Paint
Art meets science in this bubbling, colorful experiment.What kids learn:Chemical reactionsCreativity and experimentationSensory exploration
Water Refraction Experiment
What kids are observing is called light refraction—the bending of light as it moves through materials of different densities (like air and water). This principle is used in lenses, telescopes, magnifying glasses, and even your eyes! Get the tutorial Here.
Invisible Ink Experiment
Kids learn about acid base reactions.Get the tutorial Here.
Magic Milk Experiment
A classic and colorful experiment that introduces basic chemistry.Kids will Cause and effect, Color mixing, Surface tension. Get the tutorial Here.
Oil and Milk Experiment
Kids will learn gravity, immiscibility, gravity and movement from this experiment. Get tutorial here.
Floating Dry Erase Experiment
It’s a cool way to introduce kids to basic science concepts like density, solubility, and surface tension, while also encouraging creativity. Get the tutorial Here.
