Mr. Kelley’s 8th Grade Science – February-March Unit Plan Energy - The Cause of Motion (pp. 144-166 PH Science Explorer) See also: Assessment Study Guide found on pp. 166-173 Sub-unit Description (What causes an object’s motion to change/) Energy, work, and power Potential energy vs. Kinetic Energy Forms of Energy Transforming Energy from one form to another Law of Conservation of Energy Energy created by fossil fuels Key Vocabulary Words Kinetic Elastic Potential Thermal Mechanical Nuclear Electrical Chemical Magnetic Electro-magnetic Fossil fuel Combustion Oxidize Greenhouse gases are: SO2 sulfur dioxide CO2 carbon dioxide NO2 nitrous oxide CH4 methane Student Objectives/Goals (Students will be able to:) Differentiate among gravitational potential, elastic potential, and kinetic energy Know that kinetic energy depends on mass and velocity, elastic energy depends on deformation and materials, and gravitational energy depends on height and mass (graphic organizer) Know the Law of Conservation of Energy and apply the law in daily energy transformation scenarios Understand the relationship between use of fossil fuels and climate change Video Clips Click here to see a video called “The 7 Forms of Energy.” Click here to watch BrainPop movies about these 6 topics: Kinetic energy Potential energy Energy Forms Electricity Acid Rain Nuclear Energy Hands-on activities, demonstrations, weblinks, Virtual Labs Click here to use a Virtual Lab demonstrating potential and kinetic energy Click here to study an animation of the energy transformation shown in a pendulum (cgp-3053) Use the SciLinks webcodes below at www.phschool.com Scn-1351 - Energy Scn-1352 – Forms of energy Scn-1354 – Energy Transformation Assessment Help Click here to take the self-check quizzes and Chapter Test for GRN Chapter 24.
