Next Generation Science Standards Core Ideas: Motion and Stability: Forces and Interactions

This is the ninth in a series of 12 web seminars that focus on the disciplinary core ideas of the Next Generation Science Standards. Presenter Alicia Alonzo, Michigan State University, begins with an overview of how disciplinary core ideas fit into the overall structure of NGSS. Then she and Alex Robinson, a teacher at Thornapple Kellogg High School in Middleville, Michigan, discuss common student preconceptions related to motion and stability: forces and interactions. They also show how this disciplinary core idea progresses across grade bands. The program features strategies for teaching about physical science concepts that answer questions such as "How can one explain and predict interactions between objects and within systems of objects?"
