Grade 3 Science - Forces Causing Movement
Grade 3 students will learn about the ways in which forces create movement in objects - for example, that some movement results from an imbalance between forces, and some from the release of stored energy. They will learn the two basic types of forces that cause movement. The first is called a contact force such as a push or pull between surfaces that are in direct contact. The second type of force is non-contact such as a magnetic or gravitational force. In addition, the study of forces will enable students to expand their understanding of control by designing and making devices that use a form of energy and can apply a force to another object.
