3 Resources Online Textbook: Access Code: C91CBECB09 If you have difficulty connecting to the site contact Glencoe customer service on that website. Identify yourself as Ms. Hartsfields Science student at Cedar Grove Middle School. They will insure you get connected. If you have existing low grades or missing grades shown in Parent Assistant read the narrative for the details of the assignment. Complete the assignment and turn it in. NO LATE WORK will be accepted after Monday April 15. This CRCT Prep instruction will be posted on the Science Classroom Website Calendar. Science – Your Dictionary:

4 Energy and Its Transformation S8P2: Students will be familiar with the forms and transformations of energy S8P2b: Explain the relationship between potential and kinetic energy. S8P2c: Compare and contrast the different forms of energy (heat, light, electricity, mechanical motion, sound) and their characteristics.

5 Make Energy Flashcards (Word on one side, definition and illustration on the other) for the following vocabulary words: TemperatureSpecific HeatChemical EnergyNonrenewable Resource Thermal EnergyThermal PollutionRadiant EnergyRenewable Resource HeatHeat EngineElectrical EnergyAlternative Resource ConductionInternal Combustion Engine Law of Conservation of Energy Inexhaustible Resource RadiationEnergyNuclear EnergyPhotovoltaic ConvectionKinetic EnergyGenerator ConductorPotential EnergyTurbine

6 What is Energy? Copy and paste the following URL in your browser and complete the following questions: What is Energy (Pages 1&2) 1.What is the definition of energy? Potential & Kinetic Energy (Pages 1&2) 2.In the example shown, what had to be done to the car to show the difference between potential and kinetic energy? 3.How did the pendulum on page 2 show the difference between potential and kinetic energy? Forms of Energy (1-10) 4.What is electricity according to the Energy Home website? 5.What is Solar Radiation? 6.What is Mechanical Energy? 7.What types of matter are used to produce Nuclear Energy? 8.Is it correct to say a system contains heat? Explain.

7 Energy Transformations Energy Transformations (Pages 1&2) What are the energy transformations shown in the toaster example. Law of Conservation of Energy (Pages 1&2) 10.Why do the hills of a roller coaster ride get smaller as the ride goes on? 11.Make a pie chart of the End Use of Energy categories shown. Unit Review Complete the Unit Review

8 Heat Ways Heat Can Travel 13.What are the 3 ways heat can travel? 14.Define each way heat can travel and provide one illustration of each from the video. Extra Credit Do the rap from the video for the class.

9 Structure of Matter S8P1: Students will examine the scientific view of the nature of matter. S8P1a: Distinguish between atoms and molecules. S8P1b: Describe the difference between pure substances (elements and compounds) and mixtures. S8P1c: Describe the movement of particles in solids, liquids, gases, and plasma states. S8P1d: Distinguish between physical and chemical properties of matter as physical (i.e. density, melting point, boiling point) or chemical (i.e. reactivity, combustibility). S8P1e: Distinguish between changes in matter as physical (i.e. physical change) or chemical (i.e. development of a gas, formation of precipitate, and change in color). S8P1f: Recognize that there are more than 100 elements and some have similar properties as shown on the periodic Table of Elements. S8P1g: Identify and demonstrate the Law of Conservation of Matter.
