There's a Circle of Life Rediscovery blog post about outdoor maths: "6 ideas for using syringes in a mathematical way outside" written by a respected outdoor educator. It was featured as an NAEE blog last week.
This begins:
"I’ve always used syringes for water play, mark making, as air pumps in technology projects and for having fun in the snow. I’ve always chosen the biggest syringes I could find – 100ml ones. But this set, a present from a friend, fuelled the mathematical fire within me. Have a close look at the sizes and see what you notice – this is just the sort of thing to ask older primary aged children."
