Bookmark this incredible resource for your seasonal science experiments and STEM projects for kids! There are many fantastic science projects to explore for each season to recognize the changing seasons! Explore how polar bears stay warm in the winter.  learn what photosynthesis is in the spring. Engineer a solar oven in the summer or learn about why leaves change color in the fall.


Awesome seasonal science experiments and seasonal STEM activities for kids all year round


If you haven’t already visited our original everyday science experiments and STEM activities page, I highly suggest you check it out. It’s a great resource to plan your science and STEM year with fun and simple activities your kid will love.

Now, if you want to make the most of exploring seasonal changes, then bookmark this resource! You’ll find a fantastic mix of science concepts, including chemistry, physics, earth science, and biology for each season, from chemical reactions to Newton’s laws to life cycles and more!


The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.

Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As children develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.

Note: The use of the best Science and Engineering Practices is also relevant to the topic of using the scientific method. Read more here and see if it fits your science planning needs.

We have you covered…

—>>> FREE Science Process Pack


Below you will find our favorite science collections for the whole year that will be continually updated as we put together more awesome seasonal science ideas for you. Make this school year a breeze… You will find everything you need to explore winter, spring, summer, and fall with your kiddos.

Each season has FREE printable STEM challenge cards 

Grab the free mini STEM card pack of the month to add to your maker space or tinker station.

Additional science themes:

These are popular topics readers search for all year round, so I thought I would give them their own section. You may choose to study them separately from a traditionally associated season!


No need for a degree in rocket science! I don’t like sharing complicated, expensive experiments because they don’t fit our lifestyle.

My goal is to have you look through our science activities and say to yourself, “hey I can do this!”

I want you to say, “I can even do this now because I have everything I need.”

Science and STEM don’t have to be expensive, and it can be made accessible to everyone interested. Read the article on setting up STEM on a budget to learn more about how you can get started easily and how STEM can be accessible to everyone.

Check through our SHOP for awesome packs filled with great projects to go with each season!


What happens in winter? Well, it gets pretty cold in some places, and it snows! Although some of our experiments use real snow as a supply, many of our winter science activities do not! You can quickly try three of our favorites, including frost on a can, polar bear blubber, and ice fishing, even if it’s 100 degrees outside!


Do rain showers bring flowers? Spring science activities include seasonal favorites such as growing seeds, parts of plants, weather activities, rocks, life cycles, and more! Discover new ideas to explore this spring. Try this science craft (STEAM project) for parts of a flower!


School’s out, but that doesn’t mean that you have to wrap up science lessons for the year too. Our science is always so playful that kids want to dive in and learn more. Don’t stop just because of the season.

Summer is the perfect time to get outside and explore science on the go too! We’ve created 9+ Camp Weeks to get you right through the summer. A bottle rocket or DIY solar oven is the perfect summer STEM project.


September, October, November… Fall has so many fantastic science activities to explore, including apples, pumpkins, and leaves which are everyone’s favorites! Make a pumpkin erupt, explore parts of an apple, or whip up a seasonal oobleck. There are also leaves and pinecones too. Leaf chromatography is always a favorite.

Four seasons of science experiments are perfect for preschool, kindergarten, and beyond! Keep your kiddos busy all year exploring the ever-changing world around them!



We also do quite a bit with process art and famous artist-inspired projects for kids! Of course, we also love to give our art projects seasonal themes.
