Mercury barometer sim
Read 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.

- Specific heat capacity of a solid (or water) simHeat a 1.00 kg block or water with a 12 V immersion heater, read the thermometer each minute, fit a line to your graph and work out c, bare or lagged, by joulemeter or by V, I and a stopwatch.
- Cylinder rolling down a ramp: v² against x simMeasure sin θ with a half-metre rule and set square, time a rolling cylinder (or a trolley) over eight distances, fill the table, plot v² against x and find G ÷ (2 sin θ).
- Adding vectors by scale drawing simSet two forces or two velocities, pick a scale, draw them head to tail or as a parallelogram, then measure the resultant with a ruler and a protractor and compare it with the calculated value.
- Atom and nuclide builder simDrag protons, neutrons and electrons into an atom; read Z, A, the element, the nuclide notation and the charge, see whether the nucleus is stable or radioactive, and compare isotopes side by side.
- Centre of gravity of a plane lamina simHang a card from a pin at three holes, mark the plumb line each time, find the centre of gravity where the lines cross, and check it by balancing on a pencil point.
- Charging by rubbing: only electrons move simRub a polythene, acetate or glass rod with wool or silk, watch electrons move from one to the other, then bring the rod near a hanging charged rod or scraps of paper: like charges repel, unlike attract, and a charged rod pulls a neutral one.
