  1. Reminders: D ATE I can…identify different forms Agenda: of energy and explain how they 1. Entry Task impact/affect matter. 2. Making Sense of Energy Stations Entry Task: Have out: Energy Stations Activity Question: What is some evidence for: 1. Gravitational Potential Energy 2. Kinetic Energy 3. Thermal Energy Random Biology Fact : Breast feeding babies could limit their allergies to pets later in life

  2. J OURNAL Don’t forget to write in your Table of Contents! AND INCLUDE PAGE #s!  GPE Lab  Kinetic Lab  Thermal Lab  Energy Stations Guided Notes

  3. S TOMP R OCKET S TATION What energies are present? 1. Where does the KE come from? 2. Where does the initial energy come from? 3.

  4. M OVEMENT ( KINETIC ) 

  5. G RAVITATIONAL P OTENTIAL The stored energy Maximum GPE due to height above a reference point GPE becoming KE GPE = mgh Minimum GPE

  6. K INETIC ENERGY AND G RAVITATIONAL P OTENTIAL E NERGY KE max = GPE max Gravitational gravitational Gravitational

  7. P ULL B ACK C AR What energies are present? 1. Where did the initial energy come from? 2. What is the pullback energy similar to? What 3. else can you think of that bounces back?

  8. E LASTIC P OTENTIAL E NERGY The energy stored in a deformed object, for objects that have the tendency to return to original shape

  9. P OP - UP TOY What energies are present? 1. Where did the initial energy come from? 2. How is this related to the previous station? 3.

  10. M ETAL IN W ATER What energies are present? 1. Where did the energy start? 2. Where did the energy end up? 3. Did the energy change forms at all? 4.

  11. T HERMAL E NERGY L AB R EVIEW 3 factors determine the amount of thermal energy in a substance  Type of substance – Different materials can hold more or less thermal energy. The more it holds, the slower its temperature changes. Water slower to heat – holds more thermal Kettle gets hot fast! – hold less thermal  Mass of substance – More Mass = More particles holding energy  Temperature of substance

  12. C LAY B ALL D ROP What energies are present? 1. Where did the energy come from? 2. What happened to the clay? 3.

  13. W HAT IS D EFORMATION ? The transfer of KE to thermal energy causes a change in shape of substances (visible in soft substances)

  14. S OUND Organized movement of particles – Turns to thermal energy once organization is lost

  15. S OUND Organized movement of particles – Turns to thermal energy once organization is lost

  16. C IRCUIT What energies are present? 1. Where did the energy start? 2. Where did the energy end up? 3. How did the energy travel? 4.

  17. C HEMICAL P OTENTIAL E NERGY The energy stored in the arrangement of atoms NEW MOLECULES ATOMS TELL YOU BONDS TELL YOU ABOUT MATTER ABOUT ENERGY NEW FORMS OF ENERGY  THERMAL and LIGHT CHEMICAL REACTION

  18. E LECTRICAL E NERGY The transfer of energy through wires

  19. L IGHT Electromagnetic radiation in the form of waves Visible and Invisible Spreads out into environment

  20. F ORMS OF E NERGY AND W AYS TO T RANSFER E NERGY Forms of energy Ways to transfer observed in objects energy: at the stations:  Mechanical Energy  Gravitational Energy (Work)  Kinetic Energy  Heat Energy (Heating)  Thermal Energy  Electrical Energy (Electricity)  Elastic Energy  Light Energy  Chemical Energy (Radiation)
