50+ Fun Science Projects for Toddlers & Kids

    Looking for some fun things to do with your toddlers and kids? Why not break up the boring with some SCIENCE projects for kids!

    Our 4 kids are (thankfully) still at ages where we can get them to do things together. My husband loves to break out the science when they start complaining and need something to keep their minds occupied.

    From learning about electricity, to watching a chemical reaction — your kids will love to get their hands dirty with Science. Don’t tell them this, but they may actually learn something… shhh…..

    We have an on-going list of 50+ Science Projects for Kids that we’ve rounded up. Do you have a science project we didn’t list? Leave a comment and we will add it to the list!

    Science Projects for Kids

    Floating Egg

    An egg sinks to the bottom if you drop it into a glass of ordinary drinking water but what happens if you add salt? The results are very interesting and can teach you some fun facts about density.

    Build Your Own Fog Tornado

    As the fan forces air out of the chamber, air from outside the box is forced in through the slots on the sides. The position of the slots causes the incoming air to create a VORTEX (spiral) of air as it is drawn up and out of the box. Real tornados form in a similar way using updrafts and wind-shear (wind from different directions at different altitudes)

    Microwave Lightbulb

    Microwave Lightbulb Science Project for Kids

    Microwave appliances work by sending out tiny waves of energy, called microwaves. These waves of energy pass through the glass of the light bulb to excite the tungsten filament inside. The tungsten is thin enough that it glows when excited by the energy waves. This is the same thing that happens when an electrical current, like the one from a light socket, passes through the tungsten filament.
