Evaluate how magnets cause changes in the motion and position of objects, even when the objects are not touching the magnet.
In this unit, students focus on the science phenomena of electric and magnetic forces. In this lesson, students build on their knowledge of forces by exploring electric forces. They analyze how materials can become either positively or negatively charged, and then use an electroscope to explore how opposite charges are pulled toward one another and like charges are pushed away from one another.
In this unit, students explore the science phenomenon of how materials can attract or repel other materials without touching them. In this lesson, they investigate how magnets can attract or repel certain objects within their magnetic field. This page highlights the key components of this lesson.
In this unit, students continue to explore the science phenomenon of forces, analyzing how structures have to be able to withstand all of the forces that act on them. Students begin by testing different materials and shapes to see how they respond to different types of forces.
In this unit, students explore the science phenomenon of electric currents and electrical energy. In this lesson, students figure out energy transfers, electricity, and circuits in the context of an electromagnetic motor system. This page showcases each key section of this lesson.
