A performance task where students show understanding of simple machines and transfer/transformation of energy. Aligns with NC Essential Standards 7.P.2.1, 7.P.2.2 and 7.P.2.4. I show videos of Rube Goldberg contraptions each day and before I get to this assignment students are asking to create their own. Students who are below grade level have shown mastery with this assignment without modifications (may need additional time). Students above grade level may include more simple machines/steps to show mastery.
