As part of their science and technology project the primary 4 children have been making helicopter blades, they cut out templates and folded them to make the blades. They made a large one and a smaller one. They were checking to see which one hit the ground first. Some children also noticed that some spun clockwise and others anticlockwise. They had to figure out why this was.
They are looking forward to their visit to the Museum of Flight to find out more!
