Summer STEM Activities

Summer is coming and that means we can take our learning outside with Summer STEM Activities! Nothing makes learning more exciting for my kids than learning outdoors. There’s something about the fresh air and freedom that just makes learning more captivating. In Canada, summer tends to fly by very quickly. Often it’s over before it feels like we have even started. To make sure all of our fun plans happen during our short summer window, I created a Summer STEM Activities bucket list.

Our bucket list is filled with things we have done before and want to repeat (and often make better), plus new activities that we want to explore and try. I’ve provided links so you can check out these activities in more detail and hopefully help inspire your summer STEM activities. I hope you enjoy our bucket list with it’s 20 Summer STEM Activities!

Bottle Rockets

Always a huge hit and requested every single summer. Bottle rockets are even more fun with friends, so we are planning some rocket challenges and competitions. A simple chemical reaction sets these bottles blasting off.

Teach the Scientific Method with Water Balloons

This is a fun and messy hands on science at its best as kids conduct testing with water balloons and in the process learn the scientific method. Get ready for a lot of laughs and fun and they conduct this science experiment. Definitely do this one outdoors only!

With this activity we are teaching the scientific process and encouraging kids to use inquiry based activities to prove theories.

Dino Eggs

Hatching these cute little eggs is fun for all ages with it’s spectacular chemical reactions. This year I might try hiding some new surprises in our eggs to keep the kids guessing! You can also make our gorgeous Erupting Rainbow Rocks. This is simple chemistry at its best! But it can also get messy, making it a fun outdoor activity.

Nerf Battles and Building New Courses

Engineering challenges indoors are delicate, small, intricate, but in summer we take our engineering challenges outdoors and also turn them into gross motor challenges with some great heavy lifting during our design process! Knowing my oldest, he will also be doing a lot of video production, which should keep him busy on those rainy days editing footage.

Build a Nerf War Battlefield for a Nerf War birthday party or a summer filled with fun! A brilliant outdoor engineering challenge using upcycled items.

Tire Ninja Obstacle Course

My kids love American Ninja Warriors and the tires from the Nerf Battlefield double as an excellent tire obstacle course for the kids to traverse, ninja style! Fantastic gross motor work in addition to the engineering and physics challenges they create with these obstacle courses.

Tire Obstacle Course - Ninja Warrior Inspired Challenges For The Older Child. Great Sensory And Gross Motor Work!

Run a Lemonade Stand

My oldest is interested in earning money and learning how to start a business. A lemonade stand is a fantastic way to start learning some of these entrepreneur skills, and to practice his math over the summer. He has been busy making all sorts of plans, including adding patio seating to his “restaurant”.

Math can be a struggle for many kids, but with a little creativity you can sneak in math concepts and practice to build a firm foundation for math mastery.

Study of Wind Power

Over the winter we really enjoyed learning about wind power with our indoor engineering activity. This summer we want to take our wind studies outdoors with a few summer STEM activities and experiments. We are planning on building an anemometer and a kite.

Wind Power STEM Challenge - Mission: Lego Rescue. A fantastic STEM challenge that encourages the creation of mechanical energy with a tinker box windmill to "rescue" a minifig.

Make Seed Paper and Seed Bombs

The summer is a great time to watch the world around us blossom and grow. Making seed paper and seed bombs is the perfect summer activity. And with our special STEM twists, it is also some powerful hands on learning that will be enjoyed by your kids all summer long!

Build a Bird Feeder STEM Project

Grab some recycled materials and build some innovative bird feeders to attract natural wildlife to your yard this summer.

Gardening & Build a Food Powered Battery

We are blessed to live somewhere that allows us to have land and the opportunity to grow our own food in large gardens. Gardening has become a family affair this year and as my kids learn how the seeds sprout, flower, bear fruit and how to check when the food is ripe. I feel great that I’m connecting them with nature and the origins of how their food is created before it gets to their plates.

Plus we can use items from our garden to build a natural battery! We have built Lemon Batteries, Pumpkin Batteries and Potato Batteries! I wonder what else we can create a battery with from the garden???

Fall Harvest Fruit Battery Circuit activity
Learn all about electricity, batteries, power and more by building a Lemon Battery in this science experiment
Build a potato battery that powers a light bulb. A fantastic STEM activity and science fair project exploring circuits and energy production.

Engineer a Craft Stick Launcher

When it comes to working with craft sticks, my kids want to make projects that are “cool”. So what does that mean? Apparently these craft stick launchers count as extra cool! This is a great engineering and crafting challenge. The result is part crossbow, part slingshot, all fun! After building your launchers, have a competition to see how far you can launch and sneak in some math? Who can engineering the best launcher that shoots the farthest?

Popsicle stick crafts are all the rage with kids especially when they make these wicked launchers

Giant Bubbles and Wand

Kids love bubbles, so it only makes sense that going BIG will be a big hit this summer! In this Giant Bubble activity learn the special giant bubble juice recipe, then learn how to engineer the perfect giant bubble wand. Then prepare for hours of enormous bubble fun!
