‘Tis the season for science fair projects! We had our first science fair experience last year when my oldest son was in kindergarten. I was truly amazed (and overwhelmed) at the complexity of some of the kindergarten science fair projects. As a former teacher, I wanted to make sure that my son wasn’t just showing off a cool science experiment…I wanted him to do it himself and be able to understand and explain the science behind it!
One of my biggest pet peeves (as a teacher and now as a parent) is when I see parents doing projects for the kids and then try to bring them up to speed. Kids are more than capable of doing most of the work themselves…even kindergartners (with some guidance)!
How To Choose A Science Fair Project
My #1 tip for science fair projects for kids is to go try to answer a question surrounding something your child is interested in! This will ensure that it is child-led and that your child will want to find the answer to his/her question!
Example of Our Kindergarten Science Project
Big brother was very interested in space and so we attempted to answer a question regarding craters on the moon for his science fair project last year.
As you can see, he did most of his project on his own…including asking Siri to find out the answer! Haha! :)
25+ Awesome Science Fair Ideas for Kids
I’ve broken the following science fair projects for kids appropriate for primary students (K-2) and elementary students (3-5). Since I am a firm believer in kids taking the lead, the ideas for younger kids are simpler and easier to understand. The ideas for older kids tend to take more knowledge about the scientific process.
Science Projects for Primary Students:
What is Blood Made Of? A hands-on model of the parts of blood!
Why the Human Body Needs both Muscles and Bones: A simple explanation
How Do Arctic Animals Stay Warm in Icy Water? (use two zip-top bags instead of the gloves so that the whole class can try it out).
