STEM Activities And Ideas

I have written about more than 100 STEAM activities for kids on this blog.

This includes all ages from preschoolers up to high schoolers. Feel free to use them as part of your STEM curriculum or as after school, screen-free activities.

Each link below links to a specific collection of STEM activities based on a common theme. That theme could be holiday, topic, or age level. I don’t know what you’re looking for in a STEM activity, and every family is looking for something different, so hopefully this organizational method makes it easy for you to find exactly what you’re looking for.

And remember – if there is ever anything you are looking for that you can’t find, please feel free to send me an email! I love hearing from my readers and I always do my best to honor custom requests. You can reach me at charlene@hessunacademy.com

And now for your STEM activities roundup. Enjoy!

STEAM and STEM Activities for Middle School Students

Middle school students are hovering somewhere between child-like adventures and mature teen activities. This can be an awkward age for many kids but just because they’re growing up doesn’t mean the days of hands-on activities are over.

STEAM and STEM Activities for High School Students

High school students can enjoy STEM activities too! Teens love hands-on activities and these activities are easily adapted to lessons and topics that your high schooler is enjoying.

STEAM and STEM Activities by Topic

If you’re looking for themed STEM activities rather than activities by age level, this is the collection for you.

One of the easiest ways to combine learning with holiday fun is by enjoying some holiday-themed STEM activities. You can find my entire collection of holiday STEM activities here or you can look below for specific roundups I’ve written.

The larger collection includes random holidays that I have only written one or two activities about (such as Easter and Chinese New Year for example), and the collections below each contain at least 10 activities.
