Students are introduced to the anchor phenomena of forces, the ways they interact, and their effects. This investigation starts out with an exploration into observable phenomena including motion and resistance to motion (friction).
Students explore the phenomenon of magnetism. They test properties of magnets to study their force. They develop a model of magnetic fields and use it to explain magnets’ force over distance.
Students complete an electric circuit. They then explore a new phenomenon: electromagnetism. They build an electromagnet and engineer improvements to increase its strength.
Students investigate the phenomena of human energy use. They describe motor and generator designs in terms of energy transfer. They consider electricity use, generation, and implications for renewable and nonrenewable energy use.
