STUDY YOUR ETYMOLOGY ALL THE BLUE SHEETS! How should I begin to prepare for the midyear exam? 1. Get organized. Find all the tests from this semester and the study guides completed for each test. 2. Go over old tests. Correct the mistakes made the first time around by looking up information in notes, labs and textbook. 3. Highlight things that you do not remember and/or do not understand. These are the topics you will want to spend the most time studying for the exam. 4. For topics that you feel confident about, take a little time to review them and be sure that you remember them correctly. (Don t just ignore them.) 5. For topics that you do not remember or understand, go over related sections of study guides and practice questions. Make notes on a note card (handwritten) to help you remember things that you might easily confuse.

The scientist who described the laws of planetary motion was 1 st law: Planets orbit the sun in shaped paths, with the sun at one focus. During its orbit around the sun, a planet s distance from the sun changes. What is the difference between a circle and an ellipse? 2 nd law: A line from the planet to the sun sweeps through equal areas in equal time. As a planet orbits the sun, its speed is (slower / faster) when it is closer to the sun than when it is farther from the sun. 3 rd law: A planet s period of revolution gets (shorter / longer) as its distance from the sun increases. The planet with the shortest period of revolution is, and has the longest period of revolution. 11. Based on Kepler s laws: Label on of the points in the ellipse on the right as the Sun.

List the types of radiation in the electromagnetic spectrum in order of increasing wavelength: short long List the colors of visible light in order from longest to shortest wavelength: long short 3. For each pair listed, circle the one with more energy: gamma OR x-ray radio OR microwave visible OR ultraviolet visible OR infrared gamma OR radio microwave OR x-ray 4. For each pair listed, circle the color that has more energy: red OR blue orange OR green violet OR yellow For each pair listed, circle the color that has the longer wavelength: orange OR red blue OR violet green OR orange 5. What is the source of energy for Earth s atmosphere? 6. Energy is transferred FROM (hotter/colder) objects TO (hotter/colder) objects. When a substance takes in energy, it (absorbs/radiates/reflects) energy. When a substance gives off energy, it (absorbs/radiates/reflects) energy. When light rays bounce off a surface, it (absorbs/radiates/reflects) energy.
7. Match the type of energy transfer with its definition and state of matter in which it occurs. radiation a. movement of substances due to density differences conduction b. energy transfer by waves across space convection c. molecule to molecule energy transfer by direct contact d. most efficient in solids e. most efficient in fluids (liquids and gases) f. no molecules required 8. Match the type of energy transfer with examples of each process. radiation a. ironing a pair of pants conduction b. circulation of heated air in a room convection c. getting a sunburn d. heating food in a microwave e. boiling water in a pot f. frying a pancake 9. Darker surfaces absorb (more/less) energy and reflect (more/less) energy than lighter surfaces. A substance that absorbs more energy will radiate (more/less) energy. Land surfaces absorb energy (faster/slower) than water and cool off (faster/slower). 10. Explain how temperature and density differences in a fluid cause convection. As a substance heats up, its molecules move (faster/slower) and (expand/contract). This causes volume to (increase/decrease) and density to (increase/decrease). The substance (rises/sinks). As the substance cools, the opposite occurs: molecules (faster/slower) and (expand/contract); volume (increases/decreases) and density (increases/decreases). The substance (rises/sinks). Warm air is (more/less) dense than cooler air, so warm air (rises/sinks). 11. Draw and label a convection current.
