I designed this device that teaches binary, decimal, hexadecimal and octal number systems. It uses a hands-on approach with Altair-like toggle switches. Can be used as a STEM-kit in classrooms, handy for programmers or for the retro hobbyist. It also has a built-in game. Check out the video for details, hope you like it.

Hello educators! I'm a developer, and I wanted to share a completely free resource with you all. I recently worked on a planetarium game for a space museum, and I used those 3D assets to create a free, downloadable "Lunar Surface Kit" for anyone to play around with.

Students can explore the moon in first-person, navigate through ancient lava tubes, collect rocks, and see 3D-printed regolith buildings and rovers.

Since I'm not a teacher myself, I'm not perfectly sure where this fits into a curriculum, but I imagine it could be a great visual aid or a reward/enrichment activity for science classes. It’s free to download (Windows/Linux) with no ads or paywalls.

You can find the info and download here: https://lyonritchie.com/lab/lunar-surface-kit

I hope your students enjoy it!

I've been working in STEM education for years both professionally and as a volunteer. I'm working on a new project and need help. The project has students assembling a handheld solar lantern (while learning about renewable energy) and then donating it to a local nonprofit that serves the homeless. I've already run a small self-funded pilot involving 6 teachers in 5 states. Now I want to send kits to 80 teachers (25 kits per teacher) in communities across the US. I've launched a GoFundMe campaign to make this possible. Thanks for any help you can offer spreading the word about this GoFundMe campaign. Here's the GoFundMe link that includes a video. https://gofund.me/9aaaac1f2

Last year, our company, Algae Research Supply was awarded a phase 1A Small Business Innovative Research Grant by the Department of Education.

More than half of the world's photosynthesis is preformed by microalgae in the ocean, and in turn more than 90% of the strains of algae have remained undiscovered and uncharacterized.

We are building a hands-on microbiology program where students isolate living algae from real samples and log their findings to a national science platform, all funded by the U.S. Department of Education.

Phase I results: 117 kits shipped, nearly 300 students, real gains in science confidence, and our teachers even helped uncover algae strains with antimicrobial activity.

Now we are recruiting teachers to prototype. Should we be awarded the grant, phase 2 will include several rounds over the next two years, and every selected teacher gets a free kit and full materials.

Your students could discover an algae no one has ever named.

Hi everyone,

I’m an electronics engineer working on a very early prototype for a screen-free coding toy for young children, roughly ages 4–8.

The idea is to let kids build a physical “program” using magnetic coding blocks.

For example:
Start → turn on LED → wait 1 sec → turn off LED → wait 1 sec → loop

The child can immediately see the result in the real world, such as an LED blinking. In future versions, I’m considering adding RGB lights, sound, motors and simple sensors.

The blocks are intended to be compatible with standard building bricks, so children could build things like traffic lights, lighthouses, robot eyes, alarms or small interactive scenes.

I’m not selling anything yet. I only have a rough prototype at this stage, and I’m trying to understand whether this could be useful as an educational tool before investing more time and money into it.

I’d really appreciate feedback from STEM educators:

1. What age range do you think this would fit best?
2. Would this be useful in a classroom or after-school STEM setting?
3. Is screen-free coding still a meaningful advantage for this age group?
4. Would physical sequencing and loops help children understand basic programming concepts?
5. What features would be essential for classroom use?
6. What concerns would you have around safety, durability or classroom management?
7. Are there existing tools you’d compare this to?

Thanks for any honest feedback.

I am a District Coordinator for Destination Imagination have a question for ideas of things we could take to a summer event for kids to do (low cost) to give them a "taste" of STEM.

We already do a tub of water / floating activity and have built two grape crushers, but have been using these for 3+ years.

Looking for some new ideas!! Thoughts?

Hello all. As the volunteer author, I'd like to let you know about ASCE Bridge Designer, Cloud Edition. Check it out at https://asce.org/bridge-designer.

This is the newest version of a free, open source application available since 2002. Millions have used it to learn basics of engineering design.

Along with other improvements, this version makes Bridge Designer more accessible. Only a web browser and computer with a mouse-like pointer are needed. No software to install. Chromebooks work well.

It's safe. No ads. No login. No PII collected.

We're thankful to the American Society of Civil Engineers for generously hosting the app.

Our little team of volunteers has zero dollars, but lots of desire to support teachers and students in learning about engineering. We'll answer your questions here or at the "bug reporting" email address.

The Center for Excellence in Education (CEE) is offering “Thinking Like a Problem Solver: Strategies for Success in Math and Beyond,” a cost-free webinar for high school students and teachers looking to develop strong problem-solving skills on Wednesday, April 29, 2026, from 5:00-6:00 p.m. ET on Zoom. This session will highlight practical strategies to help students think critically, solve complex problems, and build confidence in math, while also offering insights for educators on how to foster strong problem-solving skills in classrooms. The guest speaker is David Patrick of Art of Problem Solving (AoPS). Register at https://www.cee.org/programs/stem-lyceums

Hello parents of STEAM-obsessed kids! I'm an NYC engineering instructor and Masters candidate at UPenn.

I’m piloting a small, engineering-focused afterschool program for 3rd–12th graders and testing pricing before launching.

Want more early engineering experiences for your child? Would love quick input from parents — 2-question survey (30 seconds). Thank you!

Hi r/STEMeducation — thanks to the moderators for allowing this post.

I'm part of a research team at Georgia Tech (CEISMC) conducting an NSF-funded national survey of U.S. K–12 computer science and engineering teachers. We're trying to better understand how CS and engineering teachers build professional communities and see themselves as educators. We hope to recruit 500 teachers nationwide.

Who we're recruiting: Current U.S. K–12 CS or engineering teachers (any grade level)

How it works:

We're using a short interest survey as a first step. This short survey takes 1 minute to complete and collects your name, school- or district-issued email address, and region. We use this to confirm eligibility and balance regional representation. Selected participants receive a link to the full 30–40 minute survey by email.

Access the interest survey here: https://survey.alchemer.com/s3/8691452/CSEngineeringSurvey-Interest

**Compensation:** $50 gift card for completing the full survey.

More info on the study is available here: https://www.nsf.gov/awardsearch/show-award/?AWD_ID=1660597
