3.1 Understand the types of energy, energy transfer, and energy conservation. Describe the energy transformation between an electric circuit and a light bulb. Describe the energy transformation between a baseball being thrown and a caught. Why are most energy transformations not 100% efficient? What factors affect gravitational potential energy? What facts affect kinetic energy? Describe the energy transformation between gravitational potential energy and kinetic energy when swinging on a swing set. What 2 things must be applied in order for an object to do work? 3.2 Understand the nature of waves. Draw and label the parts of a transverse wave. Draw and label the parts of a compressional/longitudinal wave. How are wavelength and frequency related? How are amplitude and energy related? How are period and frequency related? What does changing a medium do to the speed of wave? Describe the Doppler effect and what an observer would hear. Why? List the electromagnetic spectrum from lowest to highest frequency. Why are higher frequency waves more damaging to humans? Illustrate reflection, refraction, and diffraction. What happens to light and sound during constructive interference? What happens to light and sound during destructive interference? 3.3 Understand electricity and magnetism and their relationship. What are the 3 ways to create a charge on an object? What are 3 ways to create a voltage difference? Explain how electrons move around a series circuit. What 3 things affect the resistance in a wire? Draw and label the circuit symbols. Compare/contrast series and parallel circuits. What will batteries do to the voltage when wired in a series circuit? In a parallel? What are 3 ways to strengthen an electromagnet? Explain how generators create electrical energy.
