My favourite element in school was always magnesium, I liked all the experiments and thought it looked impressive 🙂 I generally do events around schools in Wiltshire because I live in Salisbury!
@Longcroft lasers well it would have to be iron. It’s what I live with day in, day out. The planetary cores of all the terrestrial planets are made of it. It is a remarkably complicated element because it is metallic and magnetic. It also forms my favourite mineral, pyrite, with it’s interlocking shiny cubes.
I have taught at lots of schools, mainly in London, both primary and secondary. I normally teach them about rocks and minerals, and volcanoes and earthquakes. But I have also been a teacher and taught science in secondary school. Then I was making hot air balloons, rockets and there was a lot of fire I seem to remember. Including having to ring the fire alarm.
Fun fact: to an astronomer, anything beyond helium is a “metal”. This drives all non-astronomers crazy. I’m quite taken with Carbon and Oxygen though – they’re such key things to all of life.
Most of my teaching so far has been in other countries! Need to start doing things in the UK soon 🙂
