The Bridges STEMventure module covers bridge design (physical and virtual), a hands-on approach to the engineering process, and a study in static forces related to bridges.
Using an online platform of your choice, take your pupils through the story. They have to escape from an archipelago by building different types of bridges and sharing them with the rest of the class via live video or uploaded video and images to the class folder. The story provides historical bridge design helpers along the way to direct and facilitate learning. Allows teachers to incorporate local bridges for extra enhanced research and study.
