NGSS Grade 3 Motion and Stability Forces and Interactions Predicting Patterns of Motion InvestigationsIn this activity, students design and conduct investigations to find out what happens when objects with different masses collide. Students compare an empty can to full can rolling down a ramp and colliding with a box. They make observations and measurements to provide evidence that a pattern can be used to predict future motion. Then they are provided with an opportunity to test additional objec
