Today we melted ice over a fire and watched it turn into water vapour. I had hoped to find ice in the woods but we had a badly timed thaw!

We also conducted and estimation assessment – groups were asked to line up 8 sticks ranging in size from about 10cm to 1m. We then approached individuals with a stick and asked them to decide where it should go in their scale. We also asked them to estimate how long the new stick was. The results were very interesting. We followed this up with a spot of den-building- estimation in context.
