Cool Science Experiments for Kids

Since computers have proliferated throughout the world you might think that regular science experiments have gone by the wayside, but nothing could be further from the truth. Kids still love to see homemade volcanoes erupt and flow fake lava down the mountainside.

Some Cool Science Experiments You Can Do With Your Kids

There are hundreds of cool science experiments that you can do with your kids to get them interested in science, math and nature, let’s take a look.

Science Experiment 1: Watching Plants Grow

The first thing you’ll want to do is find a craft store that sells acrylic in sheets. If you can, just get some leftover pieces that another customer has discarded as waste, you won’t need a lot. Take a 1″ X 1″ piece of wood and cut it into three equal pieces, then connect them together in a “U” shape with nails. Now place a piece of clear acrylic on each side, securing them with small screws.

You now have a small terrarium that you can watch various plants grow in, so fill it with dirt and plant some seeds that grow quickly like beans, sunflower seeds, melon seeds and squash are all very fast growing. You should plant the seeds close to the clear plastic so you can see them sprout, water lightly.

After just a few days to a week, you’ll have plants growing in your little experiment. You’ll be able to see their roots, stems and eventually leaves growing. You can do several other experiments by changing the position of the plants in relation to the sun, then watch the plants change their growth to reach towards the light.


Science Experiment 2: Boiled Egg and a Baby Bottle to Show Vacuum

This is very easy to do. You start with a glass baby bottle and a hard boiled egg. Then  you show that the egg doesn’t fit into the bottle without force. But, if you take a small piece of paper and light it on fire, drop it into the bottle and put the egg on top, you’ll see the fire consume the air inside the bottle and suck the egg inside.

This is a perfect example of how a fire consumes air, and when there is no air, there is a vacuum. The vacuum should make a resounding swoop sound as the egg pops inside the bottle. You can do this experiment several times with the same bottle and few eggs. If you want to eat the eggs, rinse the ashes out of the bottle with water, slice the eggs in half with a knife and pour them out onto a plate. That’s a cool science experiment.

If you’d like to show kids how strong raw chicken eggs are, you can have them place one in their hand and squeeze equally as hard as possible and they won’t be able to break the egg. However, when pressure is placed unequally on the shell it will immediately crush the egg and make a mess. Best to do this experiment outside.

Having fun with science experiments is easy with very few props and a little preparation. You can find thousands of things to do for all ages by doing a quick search online. The experiments are divided by age groups to keep things easy for all to understand, plus there are explanations for why each experiment works the way it does.
