Mechanisms: Wheels and axles

In this topic, children are given the opportunity to problem solve and experiment with mechanisms to help them develop a clear understanding of how they work. The children assume the role of a mechanic and troubleshoot why certain wheels don’t rotate. They then demonstrate their learning by designing and building their own moving vehicles.
