Science Projects For Kids

scienceThere are literally hundreds and hundreds of science projects that you can get your kids involved in. To begin with, the word “science” covers a wide range of subjects. There are chemistry projects, physics projects, and biology projects, as well as earth and space projects, projects involving microscopes, and much more.

For young children you can do no better than start in your own backyard or your local park. Consider all of the animals and birds that live there, and then begin to look for their homes. Birds live in nests, so you may want to teach your kids to look up in tree branches or in hedgerows and see if there are any bird’s nests there. What about spiders? Are there any spider’s webs?

Maybe there is a rabbit hole. If you go out into the country a bit, you may see rabbits hopping about in a field.

If there is a pond, are there any frogs or toads there? What about fish or newts?

You can get kids really interested in the animal world by showing them animal homes and getting them to watch out for the occupants. You can expand on this by watching what the animals are doing. Hunting for food? Cleaning its’ fur? Watching out for predators? When you get back home, get your kids to write down what they saw.

Chemical Reaction

Here is a project using a bottle, sugar, yeast, some warm water, and a balloon. Blow up the balloon two or three times in order to stretch it. Pour some warm water into a plastic bottle and put in some sugar. Shake the bottle until the sugar dissolves in the water. Add two teaspoons of active dried yeast to the water, and then put the balloon over the top of the bottle.

The yeast will begin to react with the sugar in the water and give off carbon dioxide. Check every few minutes or so, and sooner or later, the balloon will begin to inflate. The chemical reaction produced carbon dioxide and inflated the balloon in the same way that you inflate the balloon by blowing into it: you breathe out carbon dioxide. Your kids have also just discovered how bread is made using yeast. The yeast gives off carbon dioxide and the bread rises.

Evaporation

Here is an easy one. Making water disappear. All you need is a glass or a clear beaker, some water, and a sunny windowsill. Half fill the glass with water and mark a line on the glass with a felt tip pen. Place the glass on a sunny windowsill. Check every hour or two, and you will see that the water level has gone down. You can make another mark on the glass if you wish. If left for several days, the water will completely disappear.

This is simple science. The sun heats the water which results in some of the water turning into water vapor which you cannot see. Some of the water has changed from a liquid into a gas. Clouds contain water vapor, and under the right conditions the water vapor condenses and forms water droplets which fall to earth as rain. If it is very cold, the raindrops may freeze and fall as snow or hail.

Hot Air Risesscience kids

Hot air rises. Take a trash bag, a twist tie, and a long piece of string out into the yard on a hot sunny day. In a cool area, swing the trash bag about to get as much air into it as possible. Now close the trash bag and tie it up with the twist tie. Tie the string around the neck of the bag also, next to the twist tie. Now take the bag out into the sun and tie the other end of the string around something like a chair or to a fence. Over a period of time the trash bag will rise up into the air.

What happens is that the sun heats the air inside the bag which then expands. It also becomes lighter. Since warm air is lighter, it rises above cooler air. As the air inside the trash bag gets warmer it will cause the trash bag to rise up and float.

There are dozens and dozens more science experiments that you can do with your kids. Just do a search on Google and you will find enough to keep them entertained and learning for months, if not years.
