Using a pizza box - make smores or even heat pizza!

This was a great science project as we were able to involve all 4 of our kids, ages 4 - 12! The project was totally simple to do - gotta love just a few ingredients.

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.

I remember fondly of learning how to make a tornado - hopefully your kids will love this science project!

One of the most popular experiments of modern times is the Diet Coke and Mentos Geyser. This geyser tube make this fun one of our favorite and easiest science projects for kids.

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!

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.

Bust a balloon with a magnified light. Use this mystery balloon pop to show the power of the sun.

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.
