27 Simple Summer Science Experiments

Enjoy these simple summer science experiments that will inspire curious minds!

Summer is a wonderful time to let the kids show off their curiosity and do some simple science:

Mom, do you think this {non-waterproof object} will float?

If I put my popsicle down in the sun, how long will it take to melt?

and the best one that’s always asked at our house

If we put the hose at the top of the slide and turn on the water, how fast will I slide down?

They shoot off that thing like a greased pig I tell you 🙂

So in order to inspire & nuture that growing sense of curiosity — and even allow them to live a little dangerously at times — we thought we would bring you an awesome list of Simple Summer Science Experiements to try!

 Easy summer science experiments your kids will LOVE!

27 Easy Summer Science Experiments

When I complied this list, I was going for engaging activities that are:

  • easy (because complicated & summer just don’t mix),
  • use items you’ll have on hand and
  • involve fun summer experiences such as water, sand, sunshine, etc.

We love to have some of our favorite outdoor science tools for kids on hand for impromptu science learning too.

If you plan to do a number of science activities throughout the summer months, do consider having your kids start their own science journal.  It’s a wonderful way to track what they’ve learned & keep them writing during the summer months too.

Plus, you can track which experiments you do along with any questions the kids might have — and it teaches them about the scientific process in a relaxed & colorful way.
