If you’re looking for 4th of July STEM activities or Independence Day STEM activities, this is the place for you. This year, why not add a spark of scientific excitement to your holiday festivities? Use these ideas to supplement your other STEAM-based homeschooling activities.
I LOVE STEM activities and around Independence Day, they are particularly fun because they’re colorful and explosive!

In my opinion, there are two times of year that absolutely surpass all the others.
I always joke that Christmas is the best six months of the year, and I am serious when I say that I start listening to Christmas music right around the 4th of July, and my Christmas tree is always up by Halloween.
This doesn’t mean I skip all the other holidays, rather I find great joy in celebrating Christmas at the same time and intermingling the wonderful parts of the last 6 months of the year.
But what about the other half of the year? Well, that is where my second favorite holiday gets to shine – Independence Day.
Independence Day holds a very special place in my heart. I spend all the weeks following Easter planning, prepping, and getting excited for the annual Fourth of July celebrations. And just like prepping for Christmas means Christmas music, Christmas decoration, and planning the perfect Christmas gift, prepping for the Fourth of July means enjoying a plethora of 4th of July STEM activities.

What Is A STEM Activity?
Have you ever asked what is a STEM activity?
STEM activities are ones that focus on the areas of science, technology, engineering, and math. These activities can be used in classrooms or at home to help children learn about and explore these important subjects.
STEM activities can be as simple as building a structure out of blocks or as complex as coding a computer game. The important thing is that they provide an opportunity for children to engage with STEM concepts in a hands-on way. STEM activities can help children to develop critical thinking and problem-solving skills.
4th of July STEM activities provide an excellent opportunity to combine learning and fun, allowing kids and adults alike to engage in hands-on experiences while exploring the wonders of the world around us.
They can also spark an interest in STEM subjects that could lead to a lifelong passion for learning.
Whether your child is just beginning to learn about STEM or is already well on their way to becoming a STEM expert, engaging in STEM activities is always a valuable experience.

The Best Fourth of July STEM Activities For Kids
We've got the best collection of 4th of July STEM activities for kids of all ages! Celebrate Independence day in style.
One of the best parts about the Fourth of July is the fireworks celebration, and some of the best at home stem challenges include blowing things up. A sodabottle rocket using mentos is one of the simplest ways to enjoy some Independence Day explosions from the comfort of your own home.
Using adult supervision, older kids can build and assemble their very own soda bottle rocket using the wonders of mentos candies and diet coke. Or if you’d rather go for a simpler version, this article also includes ideas for diet soda geysers.
We did a fun science experiment with rock candy the other day, and we had a blast! And when you use seasonal colors (food coloring or kool-aid) this is the perfect 4th of July treat!
It doesn’t heat up the house, and it gives the kids something fun to look forward to for a few days. And finally, Independence Day rock candy is fun to eat outside during other summertime play.
When you say Independence Day, certain words come to mind. Explosions, summertime, and outdoor activities are just a few of these words and this exploding sidewalk chalk activity brings together all three.
This Fourth of July STEM activity is fun and simple for kids of all ages. All you need is corn starch, food coloring, water, and vinegar. Mix it all together in a plastic baggie, zip your baggie shut, and wait for the explosions to happen! Just use red and blue as your colors to make this an Independence Day-themed activity.
This 4th of July, make some red, white, and blue elephant toothpaste! With the proper colors, this elephant toothpaste experiment can double as a safe, indoor, child-friendly firework! What could be better than that?
While the kids are waiting for the evening celebrations to start, why not help them get some of their extra energy out with some homemade tin can ice cream?
Tin can ice cream is a fun way to enjoy a delicious treat that the kids had to make with their own two hands – and feet! STEM takes a front seat in this scientific activity.
Slime is not something you would typically associate with being a 4th of July activity, but when you use American Flag colors and throw in a little red, white, and blue glitter, you’d be surprised at how patriotic this fun preschooler friendly STEM activity can be.
Why, even kids first grade and older will enjoy a little slime fun!
Turn a seemingly simple household candy into a fun science experiment.
Learning that involves eating is always a win in my book. This STEM activity is super simple and a fun way to incorporate learning into the Independence day season, especially when you buy red, white, and blue skittles.
These baking soda vinegar fireworks are super cute and so fun! Taking a familiar chemical reaction and tweaking it to make it seasonally friendly, this is another fun STEAM project your kids can enjoy during the summer, and especially near the Fourth of July.
Salt painted fireworks are a fun activity for preschoolers, kids in first grade or second grade, or even older elementary-aged kids. Why, even I love doing this kind of thing.
I am not what you would call artsy by any means, so a simple arts and crafts activity such as these salt painted fireworks is the perfect 4th of July activity for my STEM loving family.
And at the end of it, you’ll have a beautiful fireworks display with which to decorate your home! What kiddo wouldn’t love that?
This STEM activity is surprisingly simple, and you can enjoy it using ingredients you likely already have at home.
This July 4th, why not bring your own homemade confetti poppers to the celebration? After all, confetti poppers are the next best thing to sparklers when it comes to child-friendly science fun.
DIY confetti poppers are one of the best crafts for kids to do, and this summer STEM activity is perfect for the 4th of July.
Making these poppers is not as complicated as it looks. And aren’t they so festive?
If your kids are anything like mine, they are going to LOVE these marshmallow shooters. Using simple, dollar store friendly supplies, your kids can enjoy an afternoon of building and crafting, followed by an evening (or more) of laugh-out-loud, run-around fun.
Experiment with physics while determining how much force you need to apply to your balloon, and at what angle, in order to make your marshmallow go where you want it to go.
These little contraptions are an example of a great 4th of July STEM project that will invite hours and hours of fun
When you say Independence Day STEM activity, I immediately think of something fizzy. Am I the only one who thinks fizzing is commonly associated with the Fourth of July?
This STEM activity is geared towards younger kids, such as preschoolers, but that doesn’t mean older kids can’t join in on the fun if they really want to. Let’s be real here: even older kids (and adults!) can enjoy a good explosion.
Combining baking soda, vinegar, and food coloring, experiment with a familiar chemical reaction and enjoy some seasonal fizzing fun. If you don’t want to deal with a mess, turn this into an outdoor summer STEM activity that you can enjoy on the driveway or patio.
