Design Technology - Rainforest Monsters (Lower Key Stage 2)

In this unit children extend their knowledge and understanding of mechanical systems by learning about pneumatic systems. They apply this knowledge to create a rainforest monster toy with a pneumatic moving mouth. They begin by learning about how air creates movement in a pneumatic system. Using this knowledge in a focused practical task, they create a simple pneumatic toy based on the story of the wide mouth frog. They further extend their knowledge of pneumatic systems using connected syringes to understand how pneumatic systems can change the direction and amount of movement in a system. They apply this knowledge to design and make a toy based on a rainforest animal. The toy uses a pneumatic system to control the opening and closing of its mouth.
