We were very grateful for the free kit for building, testing, modifying, and racing solar cars with children. The kids learned valuable skills through teamwork by following instructions to assemble the vehicles. They solved problems, like when the car moved backwards. By experimenting with adaptations to improve speed, and applying Newton's three laws of motion, the children were doing valuable learning all while having lots of fun. If there was one drawback or challenge it was finding enough sunny days to maintain continuity and excitement. This kit would be ideal for use in terms 1 or 4 when the weather is sunnier. Overall, this was a fantastic educational tool that combined fun and learning. Thanks for sending us a kit.
