Open Bench
Free virtual science labs · Grades 1–12

Run the experiment. Keep the science.

Open Bench turns the experiments from the school curriculum into 3D labs you work through step by step. Pour, heat, drop and measure, predict what will happen, then see where you will use it in real life.

  • Predict before every key moment
  • Turn and zoom the bench
  • Soft sound, slow motion, auto-play

  1. 1Predict

    Commit to a guess before the key moment. Being surprised is how ideas stick.

  2. 2Do

    Pour, heat, drop and measure in the real order, with real quantities.

  3. 3Observe

    Watch what really happens, from any angle, in slow motion if you like.

  4. 4Explain

    The science behind it, written for your grade.

  5. 5Use it

    Where the same idea shows up in cooking, health, sport, phones and money.

Subject 01

Chemistry

What things are made of and how they change: from melting ice in grade 1 to titrations and equilibrium in grade 12.

Subject 02

Physics

How things move, push, heat up, light up and sound, starting from the basics.

For teachers
Project it

Auto-play and slow motion

Press Auto-play and the lab runs itself on the board, pausing on each explanation. Slow-mo shows fast moments at one third speed.

Curriculum

Mapped to what you teach

Every lab lists its links to the US NGSS, the England National Curriculum and GCSE required practicals, and Latvia's Skola2030.

Nothing to install

Any browser, no sign-in

Runs on laptops, Chromebooks, tablets and phones. Sound is optional and off with one tap. A virtual lab is practice for a real one, never a replacement for supervised lab work.
