Twenty First Century Physics Meets Powerwatch

We return once again to the love of my professional life: Twenty First Century Science. In section P2 we study electromagnetic radiation which might seem like real science and indeed there are elements of it (once you get past the bit about testing sun-creams, that is). When we reach the activities relating to microwaves, though, my woodar starts going off.

Remember making crystal gardens at school? Remember your introduction to the concept of saturated solutions by heating evaporating dishes full of salt solutions and watching the crystals form? How old were you when you did that? I’m prepared to bet that it was in the First Year, or Year 7 as they call it these days.
