What we've actually taught
Three weeks. Three big STEM ideas. Built and tested in real classrooms with kids at local libraries.
How much can a truss hold?
Slide more weight onto the deck and watch the bridge sag. Push too far and it gives. Real engineers design every bridge to stop way before that point.
Trusses share the load.
A truss is a triangle made of straight bars. Triangles can't squish, so the weight gets split among every bar - that's why this little bridge can hold so much.
- Load
- 8 kg
- Limit
- 38 kg
- Headroom
- 79%
Drag blocks. Build it taller.
Real physics, real collisions, real gravity. Grab any block in any direction, pull it out, and stack it on top. The tower will lean, sway, and topple just like a real one — that's the engineering challenge.
Click and drag any block — up, down, sideways. Stack pulled blocks on top to make the tower grow.

Status
Loading- Drag a block out from a side or wiggle it loose.
- Drop pulled blocks on top to stack them higher.
- Tower fell? Hit Rebuild to start fresh.
Why this works
Every block has weight, friction, and momentum. Pull one out and the load above it has to find a new path to the ground — exactly like real load redistribution in bridges and buildings. Stack carefully and the tower stays balanced; pull too aggressively and gravity wins.
Featured Activities
Check out some of our most popular projects and activities that kids love.
Build an atom, name an element
Add or remove protons, neutrons, and electrons. The number of protons decides which element you have. Try making oxygen (8 protons) - it's the air you breathe.
Element
Hydrogen
Mass: 1 · Charge: 0
Protons
Positive (+). Decides the element.
Neutrons
No charge. Adds weight.
Electrons
Negative (-). Orbit the nucleus.
I didn't know I could build something that works. But I did. And now I want to build more.

My daughter had never shown interest in science before. After attending an Avanza STEM workshop, she came home and built a volcano on our kitchen table. She hasn't stopped asking questions since.

As a librarian, finding free, bilingual STEM programming that actually engages kids is almost impossible. Avanza STEM does it effortlessly. Our kids were glued to every activity.

I learned how to code and built my first Python game. I didn't think I could do something like that. Now I want to be a software engineer.
