14 released experiments: four free and ten in the teacher pack.
Interactive physics experiments, ready for class.
Four free middle-school lessons and ten paid pack experiments are ready to present. Browse mechanics, electricity, waves, fluids, and optics; new topics appear here only when they are classroom-ready.
Future Middle School additions are included with one-time pack access.
A separate advanced collection will appear when it is classroom-ready.

Density & Buoyancy: Float, Sink or Suspend
Compare the same object in two fluids and connect displaced volume to buoyant force.

Momentum & Collisions
Compare elastic and inelastic cart collisions using momentum, impulse, and kinetic energy.

Refraction & Total Internal Reflection
Construct reflected and refracted rays, apply Snell's law, and test the critical-angle condition.

Levers & Balance: Moments in Equilibrium
Compare opposing moments about one pivot and solve the missing mass or lever arm for balance.

Sound: Pitch, Loudness & Speed
Watch a longitudinal sound wave move through matter and measure its arrival at two microphones.

Electrical Power & Energy
Compare two resistive loads and see how power sets the rate at which electrical energy is transferred.
