STEM Costume Ideas

We’re well into October now, but it’s not too late to come up with an awesome STEM-related costume. Pair it with a STEM book, and it also qualifies for STEMTuesday’s annual Co-STEM contest and an opportunity to win free stuff. (

Looking for some more inspiration? Here are some ideas…


I recently included the book Mummies Exposed! by Kellie Logan Hollihan in a STEM Tuesday post. This would pair perfectly with a mummy costume, right? There’s a great little tutorial for making a handmade mummy costume from a plain, white, sheet here:

The last STEM book I read was Snowy Owl Invasion! by Sandra Markle. I can think of a few costumes that would pair well with this book. The first is a snowy owl. For an easy DIY costume, I would probably do a combination of these two ideas: and

The other idea that would pair well with this book is a bird-watcher. After all, bird watchers are who alerted scientists to the unusual snowy owl migration. What does a birdwatcher need? Binoculars, a hat, a bird field guide, and a birding journal (something to record bird sightings in).

To make this even more fun, get a group together and be a combination of birds and bird watchers, like this mom-child costume duo:


One of the books highlighted by STEMTuesday this month is Jennifer Swanson’s Save the Crash-test Dummies. A crash-test dummy costume is relatively easy to make and would be awesome paired with this book. Here’s one way to create the costume out of a disposable painter’s suit (or other work jumpsuit):

Book cover for 12 Epic Animal Adventures  +  or more

If you’re wanting an animal costume, you can check out my book 12 Epic Animal Adventures. It highlights a bunch of different animals, where they can be found, and some interesting facts about them. Here are some animal costumes that would pair well with this book:
Monarch butterfly:
Leatherback sea turtle:

My Explore Atoms and Molecules! book could be paired with some awesome costumes, too. Each element in the periodic table can easily be made into a costume using a box or a square piece of cardboard, cardstock, or posterboard. This would be something an entire classroom could do, and the students would be learning about the elements on the periodic table in the process. [The box element costumes were one of the many related activities found on the American Chemical Society web site:]

One teacher made an awesome atomic model costume using hula hoops, tennis balls, and felt circles:

There are even costumes that replicate molecules in a variety of ways.

As you can see, the ideas are endless. They can also be a great way to introduce some fun into a learning activity. And hopefully this post has inspired you t go forth and co-STEM!
