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…..

Science Projects for Kids

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

Make a Solar Oven

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.

Make 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)

Purchase a Mentos dropper to easily make your geyser!

Made popular by Steve Spangler, this experiment is a lot of fun and sure to amaze your friends and family (assuming you do it outside rather than in the living room).

Build a Super-Hoop Glider

Next on our list of science projects for kids, we have a super hoop glider.

Since objects of different weight generally fall at the same speed, the hoop will keep its “upright” position. Build a super hoop glider in no time!

How to 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.

Raw or Boiled Egg?

Surprise your friends and family with an easy science experiment that answers an otherwise tricky question.

Two eggs look and feel the same but there is a big difference, one is raw and the other hard boiled, find out which is which with this fun experiment.
