For this engineering project, I will be creating lights for a toy house that are powered by batteries. The light setup will be connected to batteries to convert chemical energy to light energy, which will turn the house’s lights on.

Audience/users: Young children who play with toy houses.

Equipment and materials needed: Lego or other building materials (possibly cardboard), wires(crocodile clip ones), small lightbulbs, batteries, 3D printer, laser cutter, glue.

Safety: This children’s toy has some possible risks. Keep the batteries away from small children in case of consumption and do not let a child’s mouth near any cables or wires.

Energy transfers:

Chemical –> light

Waste Energy:

Thermal
