Unit 3.1 Force and Motion
At the reinforcement level of instruction, students in grade 4 continue to make predictions and describe the direction and motion of objects. They describe changes in position relative to other objects or the background. Students investigate and describe how varying amounts of force can change the direction/speed of an object in motion.
At the developmental level of instruction, fourth-graders investigate the effects of a force on objects of different shapes and sizes. They conduct experiments to demonstrate that different objects fall to earth unless something is holding them up. Students describe what happens when like and opposite poles of magnets are placed near each other, and they explore the relative strength of magnets with regard to the magnets’ size and number, as well as the properties of materials.
