Today, the students worked in collaborative teams. Their goal was to design, make and test a paper boat. They were given a piece of A4 paper, a pair of scissors and a glue stick. They worked together on designing a paper boat that could be propelled by the force of a breath. After drawing their boats, they had 30 minutes to make them. We tested the boat in a water trough. Findings: we wish we had a much bigger trough!
