This includes understanding the result of the relative positions and movement of the earth, moon, sun, stars, planets, and galaxies. It also entails an understanding of how scientists gather data and formulate explanations for phenomena in space. Describe how scientists gather data about the universe. Research current explanations for phenomena such as black holes and quasars. Explain how astronomers measure interstellar distances.
Energy takes many forms which can exert forces and do work.
The conversion of energy from one form to another offers useful applications and sometimes presents problems. Analyze the evidence that leads scientists to conclude that light behaves somewhat like a wave and somewhat like a particle. Explain or demonstrate how sound waves travel. Analyze the relationship between the kinetic and potential energy of a falling object. Use mathematics to describe the work and power in a system.
