Projectile Motion
Vary angle, speed and air resistance to explore range and trajectory.
Energy Skate Park
Watch kinetic, potential and thermal energy transfer along a track.
Masses & Springs (Hooke's Law)
Investigate Hooke's law, spring constants and oscillation periods.
Gravity Force Lab
Change masses and separation to see how gravitational attraction varies.
Wave on a String
Change amplitude, frequency and tension to study wave behaviour and reflection.
Sound
See how sound travels, and how pitch and loudness relate to frequency and amplitude.
Wave Interference
Explore superposition, diffraction and interference patterns from two sources.
Circuit Construction Kit (DC)
Build series and parallel circuits and measure current and voltage.
Ohm's Law
Adjust voltage and resistance to see how current responds, V = IR.
Capacitor Lab: Basics
Charge a capacitor and investigate plate area, separation and stored energy.
Gas Properties
Explore pressure, volume and temperature relationships in an ideal gas.
States of Matter
Heat and cool substances to see solid, liquid and gas particle behaviour.
Density
Compare mass and volume of different materials and predict floating or sinking.
Buoyancy
Investigate upthrust, displaced fluid and why objects float or sink.
