Behind every tool there is
an expert.

Play with the work.
Then look behind it.

Simulations, lessons and marking tools for education, each with its rules, checks and sign-off in plain view.

We build learning tools around what teachers know.

Play with one, then look behind it.

Lesson Orbits

Sample

Orbits

  1. Fire a cannonball sideways from a mountain. Gravity pulls it down.
  2. Fire it faster and it lands further away.
  3. The Earth curves away beneath the falling ball.
  4. Fast enough, the ground curves away as fast as the ball falls.
  5. It keeps falling and never lands. That is an orbit.
  • RulesMade only from the teacher’s notes.
  • ChecksAnswers marked by code.
  • PersonThe teacher approves it before learners see it.

Check

Why does a fast enough cannonball never land?

Every mark has a reason.

Sample

A trolley of mass 2 kg accelerates at 3 m/s². Calculate the resultant force on it.

  1. F = m × a
  2. F = 2 × 3
  3. F = 6
