Image in a plane mirror sim
Find the image of a pin in a plane mirror by moving a search pin until there is no parallax, or with two sight lines, then measure u and v with a rule and plot v against u.

- Mercury barometer simRead a mercury barometer with a metre rule, tilt the tube, widen it and push it deeper to see the vertical height stay at about 760 mm, change the weather and the altitude, work out p = ρgh, and spot the air bubble that makes h too small.
- Metre rule and tape: zero error, end error and parallax simSlide an object along a worn rule or a tape, put your eye straight above each end, read to 0.1 cm and subtract the start from the end.
- Newton's third law with force sensors simTwo trolleys with force sensors tug, push, collide and spring apart. Zero the sensors, then watch both traces come out equal and opposite at every instant, whatever the masses; then sort pairs from balanced forces.
- Pressure in a liquid: depth and density simLower a pressure probe into water, salt water or cooking oil, correct the meter's zero, turn the probe and change the vessel, then plot p against h and work out ρ from the gradient; a can with holes shows the deepest jet spurting hardest.
- Ray diagram builder: converging lens simMove an object in front of a thin converging lens, draw the three standard rays yourself with a pencil and ruler, find where they meet, read the image distance and height off the grid and name the image, for all five object positions including the magnifying glass.
- Ripple tank: wave speed, reflection, refraction and diffraction simSet the dipper's frequency, freeze the waves with a strobe, measure λ over several waves and find v = f λ; then add a barrier, a shallow plate or a gap.
