The kindergarten and first grade classes learned that the plan an engineer uses when working through the design cycle is called a blueprint. They made their own by gluing paper rectangles to a blue paper. The rectangles represented the wooden blocks they would use to build a path for a Hex Bug to travel through. They then built this path from their blueprint. If the Hex Bug could not travel the entire course, we discussed why that might have happened. The students decided that the “walls” weren’t strong enough and that the engineer would need to change the blueprint and try again.
