One of the projects for the Oregon Trail unit is a STEM project where students are calculating what supplies they need to take on the journey, how much each will weigh, and not going over 2,000 lbs. Then they create a covered wagon no bigger than 10” L X 8” W X 15” Tall. It must be strong enough to hold at least 12 decks of playing cards. Each deck of cards represents approx. 160 lbs.
