This half term the Year 3s have been the challenged to design and make a sled that will travel smoothly and quickly across the snow for their Inuk friend Aput! After researching existing sled designs and learning all about friction, the classes began by testing the best surface for their sled’s base. They tested out 6 different sloped surfaces covered in: tin foil, plastic, paper, wood, silk and felt. They timed how long a wooden block took to travel down each. Then from these results decided on their own sled’s base material. It was all about avoiding friction! Just look at their amazingly stream line sled designs too…
