Ideas you can touch.
Six interactive labs for science and math. Drag, pour, zoom and turn the dials, and watch the idea work.
The Periodic TableDrag across all 118 elements and watch each one add a proton and drop an electron into the next orbital.
Chance MachineSketch a guess, pour thousands of marbles through a Galton board, and watch the bell curve build itself.
DNA to ProteinFollow a real human gene from DNA to protein, then edit it and watch one letter change everything.
Proofs You Can DragDrag a triangle, slice a circle, stack a staircase: seven proofs you can push until you see why.
Photosynthesis FactoryTurn up the sun, the carbon dioxide and the heat, and find which one is holding the leaf back.
Scale of NumbersZoom through 62 powers of ten, from the Planck length to the edge of the observable universe.
How the labs work
- Pick an ideaEach lab is one idea from science or math class, from how atoms are built to why randomness makes a bell.
- Play with itEvery lab is something to move: drag the table, pour the marbles, edit the gene. The numbers are real and computed live.
- Go deeperEach lab opens up as you go, and its About page lists the sources behind every number.
Questions
What is a lab?
One big idea you can play with. Instead of reading about how electrons fill an atom or why a bell curve appears, you drag, pour, zoom and turn the dials yourself and watch it happen. Each lab takes a few minutes and goes deeper if you want it to.
Who are the labs for?
Students from middle school up, and anyone curious. They follow what science and math classes teach, and every number and fact in them is sourced; each lab has an About and sources page.
Do I need an account?
No. Every lab is free and open, on any device with a modern browser. Sound is off until you turn it on.
Can I use them in class?
Yes. Each lab has its own address, so you can share or project it. Some keep your place in the address too, like the element you were on in the Periodic Table.
