Science Fair Projects for Kids
Participating in the school Science Fair is a rite of passage for many children.
Kids love them! But as a parent, it might cause a little bit of stress. From deciding what to do exactly to getting material to actually follow through- it could easily turn into a parent’s worst nightmare!
The hardest part in our opinion is coming up with the idea of what to do. But once you have that figured out it should be smooth sailing. Just remember to have fun and let your child take the lead (just like with these 100 Days of School Ideas).
Science Fair Projects are supposed to be fun! Yes, fun! And there a ton of great ways to make that a reality.
So when the time comes that your school is hosting one- instead of stressing out or worrying about it- be sure to check out this great list of top Science Fair ideas for all ages.
How to Pick a Science Fair Projects
As mentioned above, picking out a science fair project is one of the hardest parts of the science fair. There are a few things you should keep in mind when doing so (credit goes to Hilary from Pulling Curls for most of these tips. She’s an expert when it comes to science fair projects and all things kids! Make sure you check out her Family Routines course. It’s life changing!).
- Read the school’s science fair requirements. Chances are, there are specific kinds of projects they are looking for. Most often for the elementary school science fair projects, they will want you to use the Scientific Method, so it should be a project where you can easily change a variable.
- Make sure the child can explain it. There are a lot of cool projects out there, but if the child can’t explain what is happening, it doesn’t always work out so well. If they are giving awards for the science fair, they will typically have a big scoring section on how easy it was for the child to explain the project to others.
- Go with your child’s interests – if they really enjoy something, then make that a part of the project. The more they are interested in the topic, the more likely they are to actually want to explain and do it.
- Don’t overcomplicate it. Science fair projects don’t need to be complicated, especially for younger children. The most important thing is that they have fun!
- Let your child take the lead – yes, there will always be those projects that were clearly done by the parents. Often, these are the most complex and exciting. However, the child really should be taking the lead with the project. It’s fine to help here and there, but please resist the urge to take over.
- Is it relatable? Personally, I think the best science fair projects are ones that are relatable to your own life and that make you think!
With the projects below, make sure your child doesn’t read the final results. You don’t want that to influence their hypothesis! Please make sure you click through to each project that looks interesting to you!
