By: Jaclyn Holtzman, Editor,

Why is the sky blue? Why can I float in water? Why do volcanoes erupt? Kids love asking, "why?," so let's give them some answers. Science experiment projects for kids will provide them with not only answers, but also explanations.

Your kids are never too young to learn, and if something goes over their head, it's okay! Regardless, they'll be having fun, and no doubt at some point in their life they'll look back and it will all make sense. Science experiment projects for kids are wonderful ways to spend lazy Sundays, cold winter evenings, or long summer days. Since your kids learn something new every day, why not make that something worthwhile?

Within this list of 34 Science Experiment Projects for Kids, your kids will find simple scientific experiments as well as more advanced lessons. That means that the whole family can carry out these fun crafts together, and no matter your age, you'll pull something from the experience.

These experiments will, however, have some awesome effects. Mixing two materials together doesn't always create a reaction. Do your kids know why? Do they know why mixing two materials together sometimes creates huge reactions? Your kids can learn the answer to those questions and more when they do these science experiment projects for kids.

Science is absolutely amazing, and when you're a kid, you may even mistake it for magic. Science is responsible for everything that happens around us, and it's important to understand who, what, where, when, and most importantly why. It's no secret that learning isn't always fun, but when you're conducting science experiment projects for kids, learning is AWESOME. You're sure to hear "ooh"s and "ah"s throughout these educational activities for kids.
