Today Year 2 welcomes Mel from Northumbria University into our class. 
We looked at the science behind floating and sinking to decide which material and shape would be the best for making a boat. Later on in the afternoon we saw many parents come to join us and help us to conduct two more experiments. We found out that the shape of the boat matters and many light things can stay afloat but not many heavier things kept the boat afloat. 
What a fun afternoon!
