This document provides a scope and sequence for a 3rd grade STEAM curriculum unit on forces and interactions. The unit goals are for students to follow the engineering design process to ask questions, plan investigations, and solve simple design problems involving forces and interactions between objects. Specific performance expectations are for students to plan investigations on balanced and unbalanced forces, observe and measure motion patterns to predict future motion, ask questions about electric and magnetic interactions, and design solutions using magnets. Related math standards involve measuring, estimating, and solving word problems involving masses and volumes.
