Grade Level: 3rd Grade
A push or a pull, a force, is needed to set an object in motion. This requires objects to interact with one another. Types of interactions may be grouped into two broad categories. Direct contact between and among objects, such as friction, is one group. Interactions may also occur across a distance. Magnetic and gravitational forces are included in this category. Results of these forces are observable. Careful observations can lead to prediction of future results of interactions. The use of qualitative and quantitative observations assists in the development of predictions.
3-PS2-2: Motion and Stability: Forces and Interactions
Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
