Best Science Activities and Experiments for Kids

My kids love science activities and so do I, so we find ourselves doing them quite often lately. I love that they are learning while having so much fun.

Science experiments are a great, hands-on way for kids to explore scientific concepts. They are super engaging and exciting, so kids are really drawn into learning.

Plus, I find that they learn more when they are engaged with interactive, hands-on ways.

The experience becomes more memorable than simple reading about science or doing a workbook page on a scientific concept.

I really try to find science experiments that are simple and use supplies we already have or can easily get. I find that the easier they are to set up, the more we do them.

So if you are looking for simple science fun too, these will be perfect for you.

For each experiment, I explain the science behind them. So not only will the kids explore science in fun, engaging ways, but you will easily be able to explain the “why” behind each experiment.

Grab some simple household supplies and you will be well on your way to lots of science fun with kids.
