For engineering, we learned about series, parallel and combination circuits. We had to create a model of our district. Our district has a military base called "The Nut", academies for children to train for the Hunger Games and many small villages around a coal mine. My land mark was a village around a coal mine. For my circuits, make it a combo because one of the houses and the coal mine each have 2 lights in there. The 2 lights are in series and the 4 lights are parallel.
