Grade 3 Science, Unit 3 Electrical and Magnetic Forces
In this unit of study, students are able to determine the effects of balanced and unbalanced forces on the motion of an object and the cause-and-effect relationships of electrical or magnetic interactions to define a simple design problem that can be solved with magnets. The crosscutting concept of cause and effect, the interdependence of science, engineering, and technology, and the influence of engineering, technology, and science on society and the natural world are called out as organizing concepts for these disciplinary core ideas. In the third grade performance expectations, students are expected to demonstrate grade-appropriate proficiency in asking questions and defining problems. Students are expected to use these practices to demonstrate understanding of the core ideas. Essential questions • How do equal and unequal forces on an object affect the object? • How can magnets be used?
