1. What is energy? The ability to cause change or do work2. What is kinetic energy? Energy of motion3. What is potential energy? The stored energy that an object has due to its position, condition, or chemical composition. 4. What is mechanical energy? The kinetic energy plus the potential energy due to its position.5. What is the law of conservation of energy? Energy can be neither created nor destroyed, it can only be transformed. 6. Heat is a form of.? Energy7. If something has more heat, does it move faster or slower? Faster because more energy8. What are the 3 types of heat transfer; radiation, conduction and convection? Radiation: the transfer of energy as electromagnetic waves. Conduction: the transfer of energy from one object to another object through direct contact. Convection: the transfer of energy due to the movement of liquids and gases.9. How do differences in air pressure cause wind? Solids heat fastest, then gases, then liquids. Because solids, liquids and gases heat at different rates, it causes differences in density, which causes differences in pressure, which causes wind.10. What is the difference between sea and land breezes? During day, land hotter, less dense, so more dense air from over water moves over land. At night, over water warmer and less dense, so cooler more dense air of land moves over water.11. What is science? The study of the natural world12. What is a theory? A well-supported explanation about the natural world13. What is a model? A representation of something in the natural world14. What is a law? Basic principle of nature that always occurs under certain conditions.15. What is an experiment? An organized procedure to study something under controlled conditions.16. What is an observation? Obtaining information by using the senses.17. What is a hypothesis? A testable idea or explanation that leads to scientific investigation18. What is a variable? What is the difference between independent and dependent? Any factor that can change in an experiment, observation, or model. Independent is what is being changed in the experiment. Dependent is the result that is being measured.19. What is data? Information gathered by observation or experimentation.20. What is the scientific method? Steps that scientist can use to solve problems. Has no particular order. Define a problem, for hypothesis and make predictions, plan investigation, identify variables, collect and organize data, interpret data and analyze information, defend conclusions.21. What is the difference between a mathematical model and a physical model? Mathematical is equations and data and physical is something you can touch.
