Launch Gravitational Fields
Visualise how mass creates gravitational fields and how field strength changes with distance.
Launch Pulleys
Lift a load with 1–4 pulleys, compare effort and distance, and explore how mechanical advantage changes the force needed.
Launch Terminal Velocity
See a skydiver accelerate, reach terminal velocity, and slow safely after opening a parachute.
Launch Reflection and Refraction
Compare wave reflection at a surface with refraction as waves enter a medium at a different speed.
Launch Nuclear Reactor
Control rods, neutron capture and chain reactions in a live U-235 reactor sandbox.
Launch Solenoid
Watch a straight wire form a coil, then explore the magnetic field produced by a solenoid in 3D.
Launch Electricity Overlap
Build circuits at particle level and watch current, resistance and potential difference emerge.
Launch Ultrasound
Investigate pulse-echo imaging, reflections and how distance is inferred from time of flight.
Launch Filament Lamp I–V Curve
See how heating the filament produces the lamp’s distinctive non-linear I–V characteristic.
Launch Circuit Sketcher
Sketch clean circuit diagrams quickly with familiar components and connections.
Launch Pinhole Camera
Move the object, aperture and screen to explore image inversion, size and sharpness.
Launch Why does salt make ice colder?
Explore how salt lowers ice’s melting point and how melting and freezing transfer latent heat.
Launch Electromagnetic Devices
Explore how electromagnets power devices such as relays, speakers and electric motors.
