Analyze data to determine how a design solution causes a change in the speed or direction of an object with a push or a pull. Define the problem by asking questions and gathering information, convey designs through sketches, drawings, or physical models, and compare and test designs.
In this unit, students discover that pushes and pulls are forces that change the motion of an object. They begin by exploring how objects move in different directions when they are pushed or pulled, and then investigate how changing the strength of a force changes the distance an object moves. They then use a model to see how friction affects the distance and speed with which an object moves over a surface.
