If you're interested in finding some science experiments for kids you can do at home, then you've come to the right place! Conducting science experiments is a great way to have fun, as well as learn, with your kids. There's no better way for a child to learn than by seeing and doing things in the real world. That's why these 8 fun science experiments for kids you can do at home are the perfect weekend activity!
This idea is one of the science experiments for kids that would work great in a discussion about reactions. No worries, the foam created in his experiment is safe to touch! It is simply water, oxygen gas, and soap, so let your child touch the foam to feel texture. What this experiment shows is that hydrogen peroxide naturally breaks down into water and oxygen. It is stored in opaque containers to help slow down this process but the enzyme catalase speeds up the reaction. Dish soap catches the oxygen and makes bigger bubbles and the food coloring makes it look cool. The foam and bottle feel warm because the reaction is exothermic--it releases energy as heat!
This is probably one of the simplest and easiest experiments to perform at home. All you need is a bar of Ivory soap and a microwave! After you and your children watch the reaction of the ivory soap when heated, explore the end result through smell, touch & play! The explanation behind this experiment is that the air bubbles in Ivory soap bars contain water. The expanding effect is caused when the water is heated by the microwave. The water vaporizes, forming bubbles, and the heat causes trapped air to expand. Likewise, the heat causes the soap itself to soften and become pliable.
This experiment is simple, but involves a lot of observation and patience from your kids. However, the results are really exciting to see and the finale can be lots of messy fun! All you need is 1 white and 1 brown egg, clear cups, water, and vinegar. After only a few hours, you should be able to see that the vinegar eating away at the shell of the brown egg. Leave the eggs in their cups for 7 days and observe them each day. By the 7th day, the eggs that were in the vinegar should be rubbery and shell-less! If you want, allow your child to experiment with the new rubbery egg by trying to bounce it... be warned, it will get messy.
With this experiment, your children will learn another reaction process that will cause a balloon to inflate. Mixing baking soda and vinegar starts an acid-base reaction that creates carbon dioxide. Gasses need room to spread, so the carbon dioxide fills the bottle and then moves into the balloon, inflating it! Carbon Dioxide gas will inflate the balloons but they do not "fly" like helium inflated balloons as it is not the same kind of gas. Thus, this is meant to be an experiment, and not a fun way for you to blow up balloons for your next party.
This is a fun and colorful way to teach your kids about plant biology. All you need to perform this experiment are white carnations, glass jars, food coloring, and water. Simply add food coloring to each jar and top with water. Then, place one carnation in each jar and let the food coloring do its thing! After 24 hours you should have white carnations that are tinted to the color of the jar that it was sitting in. Coloring the water with food coloring does not harm the plant in any way, but it allows you and your kids to see the movement of water through the stems of the carnation to its top.
I'm sure most of you have heard about the reaction that happens when Diet Coke and Mentos are combined, but it is too fun an experiment to not have on this list. This activity is probably best done outside in the middle of an abandoned field, or better yet, on a huge lawn. Open the bottle of Diet Coke and position it on the ground so that it will not tip over. Unwrap the whole roll of Mentos and drop all of the Mentos into the bottle of soda at the same time. Then quickly run away and observe! Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are perfect places for carbon dioxide bubbles to form. When all this gas is released, it literally pushes all of the liquid up and out of the bottle in an incredible soda blast!
Oobleck is simply a mixture of cornstarch and water. When moved fast it acts like a solid and when allowed to relax it acts like a liquid. You will need a subwoofer, a thin metal cookie sheet, a MP3 of an audio test tone and food coloring. Place the cookie sheet onto the speaker of the sub, and pour in the Oobleck. You can download different test tones and play to see what works best for you. Turn up the sub and watch the Oobleck dance! To make it even more fun for your kids, have them add food coloring while the Oobleck dances. You will all love how the colors dance together!
This is another experiment that requires a little bit of patience but being able to see water walk is definitely worth the wait! What you need to pull this off is two cups, one full of water, one completely empty, and a paper towel. Make sure to color your water in order to make it a little easier to see. The cup that starts out with the water should be practically empty by the end of the experiment and the cup that was empty in the beginning should be holding all the water. It will take about 2 hours in total and teaches your kids both absorption and gravity.
Just because you're older doesn't mean you've run out of things to learn! Performing scientific experiments with your kids can be a great rainy day or weekend activity for all of you! Allow your children to make observations by sight, smell, or touch. If they ask what would happen if you did something else in the experiment, let them try it out to answer their own curiosity! As long as it's safe of course! Have you and your kids conducted science experiments for fun at home?
