Oh my goodness - the sun was out and we had planned a measuring lesson in the sandpit.
We were meant to be measuring water as well - but even though the sky looked amazing it was a mere 10 degrees celsius.
It was freezing cold - but that didn't stop us from measuring, comparing, testing and checking out our guesses and working as a team.
We shouldn't as kids love it and get so much out of it.
Some of this group - worked out that 2 x 500 ml containers were the same as a litre.
