The kid science projects below may require a little bit of guidance from you, but you won’t have to do the project yourself. They’re developmentally appropriate for school-aged kids. If your child needs some help articulating these projects into something on a tri-fold board
This project looks at how liquids evaporate at different rates. It’s an easy one for kids to set up and monitor themselves. It does call for beakers, which I am betting you don’t have in your kitchen. You might want to see if the school will let your child borrow a few from the science classroom for this project. If not, you can use clear juice glasses and have the kids mark the liquid levels with a dry erase marker. Dry erase markers wipe off of glass (you may need a little bit of white vinegar to help remove it), so you don’t even have to sacrifice anything permanently from your kitchen. You may need to remind your child to check on the levels of liquids each day, but that’s about it!
2. 3D Glasses
Julie Finn at Crafting a Green World home schools her two daughters and does all kinds of fantastic kid science projects with them. These kid made 3 D glasses are a great way for kids to learn how 3 D glasses work. Julie also encourages you to let your kid experiment with lens colors to see how they impact the glasses’ function.
3. How do stalactites and stalagmites form?
Your kid can use woolen thread (aka yarn) and baking soda to create her own stalactites and stalagmites! You might need to be available to help some with the setup, but this project from Science Kids looks pretty simple. Once it’s all set up, your kid just needs to remember to check in on her stalactites and stalagmites each day. Photos of the growing process would make a great display.
4. Baking Soda Balloon
This project from Science Bob is an acid-base experiment. When you mix baking soda and vinegar, they react to release carbon dioxide. If your kid does the experiment in an empty 2-liter, she can watch the results inflate a balloon. It’s easy to set up and quick to observe.
5. Gak Attack
If your kid hasn’t made gak, she’s in for a treat! Gak keeps for about a week in the fridge, so you have plenty of time to experiment. Your child can learn about polymers, and Gak is a fun toy to play with after the experimenting is done. There are tons of Gak tutorials online, but I like that Steve Spangler explains how it works in a way kids can understand.
6. Cartesian Diver
Is your kid learning about density in science class? She can turn an old soda bottle into a density experiment! Julie explains how she and her daughter created their own Cartesian diver and the basic density lesson your kid can take from it.
7. Walking Water
You know a kid can do this project, because you can see a kid doing the project right in the video. I think this would be a good way to encourage a child who’s intimidated about doing a science project this year.
Once your child has observed the magic of walking water, she can research absorption. The paper towel absorbs the water, which is how it moves from glass to glass. Coffee Cups and Crayons has a good explanation as how this works and some troubleshooting tips, in case your project isn’t working as well as the one in the video.
8. Cloud Jars
How do clouds hold water, and how does rain work? Your kid can answer these questions with this simple science experiment. This is a fun activity for even a preschooler, but older kids can dive into the science angle a bit. Have your child research clouds and rain, then perform this experiment from Learn with Play at Home to see it in action.
