In Science, we have been looking at forces and this week we are focussing on water resistance. We have looked at a number of different shapes, models and marine animals that travel through water and what makes them efficient. We have had a go at designing our own water vehicles and have built models out of a selection of materials. They are all very different in design and come in all shapes and sizes. We will see on Monday who's boat is the most efficient and who will win the Great Boat Race...!
