STEM Activities for Kids— Fall 2021

It’s back-to-school and that means you can look forward to upcoming STEM activities in the next few months. Many STEM providers have re-opened their in-person programs (yay!), so be sure to check with your local organizations and see what they’re offering.

If you’re looking for an online afterschool program, look at my latest article about fall online STEM classes. There are opportunities to create websites and mobile apps, learn to operate a ham radio, make robots, explore digital animation, perform science experiments, delve into biotechnology, and more. For most of these programs, kids will attend scheduled, real-time, instructor-led online classes, sometimes in small groups of students from around the country, sometimes with a small group of kids at your home or one-on-one.  

Here are ideas for fall activities and events—many are free! I hope you enjoy exploring the possibilities.


Discover coding workshops, travel adventures, and museum tours with Microsoft Store’s free virtual online workshops for students. Visit the website to check out the variety of programs and sign up. 

A new season of CyberPatriot, the nation’s largest youth cyber defense competition, will be starting soon.

Top teams advance through the online round of competition, and the best advance to the in-person National Finals Competition. Teams must register by October 5.

Learn about entrepreneurship programs for kids and teens in my recent article. It’s all about developing an entrepreneurial mindset when you’re young. Get ideas about programs, classes, and clubs your child can participate in. Kids will learn to bring a curious mind to solving problems and get comfortable working in an environment that tolerates risk, rewards creativity, and features some degree of ambiguity.

Every year members of Congress across the country challenge students in their districts to create and submit original apps for a chance to win the Congressional App Challenge (CAC).

Students may register as individuals or as teams of up to four. Students may compete in the district they reside in or in the district where they attend school. Students can register and submit their original apps through November 1

It’s common for teens to participate in community service today. If your child loves tech, STEM volunteering could be a rewarding experience and beneficial to your community. Learn how students are finding and creating STEM community service activities.
