Testing our boats This afternoon, the children tested their boats to see if they would float and if they could hold any weight. All the boats floated very well but Archie’s held the weights for the longest amount of time before letting water on board. After talking about our designs the children agreed that next time they would make the hull of their boats deeper so that when weight was added they didn’t sink. The boats were more like rafts. The children were keen to make another one!
