Fields and Interactions, developed by SEPUP at the Lawrence Hall of Science is the final unit in a middle school series designed for the NGSS. This unit explores the anchoring phenomenon that objects can be observed to interact with other objects even when they are not in contact with one another in the context of the unit issue: How do different types of force fields help us design transportation? Examples explored include static electricity, the behavior of magnets, and the observation that objects fall toward the earth. Students generate and answer questions such as: How do objects interact at a distance? What is a field? How does a field store energy? How do people use fields to design solutions to problems?
This unit builds towards and assesses PEs PS2-3, PS2-4, PS2-5, PS3-2, ETS1-1, ETS1-2.
