Students investigate why the moon turns red during a lunar eclipse by exploring refraction, dispersion and the scattering of white light through different media.

Students investigate transport in plants by seeing what happens when flowers are placed in different coloured solutions.

The reduction mill reduces the thickness of a strip of steel using a series of rollers, each roller making the steel slightly thinner. The percentage reduction is constant on each pair of rollers. The mathematics used to calculate the actual reduction is similar to that used when calculating compound interest....
