Mindblowing Summer Science Experiments You Must Try This Summer

When it comes to science experiments for kids, we’ve tried a lot. Science experiments are one of my kids’ favorite things to do.

During the summer, we like to kick things up a notch with summer science experiments. 

My kids are active learners. They don’t like worksheets, and they definitely don’t like sitting still. But what they do love is hands-on learning.

Science doesn’t have to be boring. These summer science experiments provide the ultimate list of science experiments for summer, teaching kids the basics of science at home. Kitchen science is so easy when you do these science projects for kids. These science experiments for elementary are the perfect summer project! #summerlearning #science #scienceexperiments #scienceclass #learnathome #summerfun #summer

Anything that my kids can get into physically while learning, they love.

That is why science experiments have become such a big part of our summer.

Each summer, we spend several weeks trying new science experiments for summer and STEM activities that are both educational, and tons of fun.

We’ve gathered a list of our favorite summer science experiments below.

Summer science experiments are the perfect way to explore science during a summer at home.  Make learning fun with these summer science activities.

Summer Science Activities

A summer science experiment is a lot like any other science experiment, except these have a summery twist!

All of these science experiments for summer include fun summer themes, like bright colors, kitchen science, ice, tie dye, space, the ocean, and more!

One of my favorite things to do in the summer with my kids is to try fun STEM activities and science experiments with them, because my kids love learning hands on, and I love learning right along with them.

Summer science experiments are one of our favorite summer traditions and have been for the past five years.

Fun Summer Science Experiments


Today, science experiments for kids are more important than ever. Science and technology are huge parts of our world today, and the future will be even more science and tech-focused.

Kids who aren’t immersed in the world of science and STEM exploration from a young age will be left behind their peers, and may struggle to find work in the fast-changing landscape of future careers.

Science experiments are usually basic, but they can help spark a love of science and discovery in a child that will follow them throughout their life.

The simple science experiment that a child does today may spark their desire to discover something that will change the world in the future.

Keep kids learning this summer with these summer science experiments. Learning doesn’t have to be a chore, and if you have active kids, these hands-on learning ideas are perfect for preventing summer slime. Make science fun with these hands-on science lessons and bring science to life! #summerlearning #science #scienceexperiments #scienceclass #learnathome #summerfun #summer

When you do your summer science experiments, try to include every step in the scientific method.

Every science experiment contains four elements:

A Question

Kids should start every science experiment with a question, even if that question is just “what will happen?”

A Hypothesis

Before doing any experiment, children should record what they believe will happen.

An Experiment

This is where the fun part comes into play. Test the hypothesis to determine if it answers the question fully.

A Recording and Analysis

As the test is completed, record what happened and analyze why.

A Re-test

Try different variables and try a new test to see if the original answer is confirmed or disproved.
