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
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
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.
M OVEMENT ( KINETIC )
G RAVITATIONAL P OTENTIAL The stored energy Maximum GPE due to height above a reference point GPE becoming KE GPE = mgh Minimum GPE
K INETIC ENERGY AND G RAVITATIONAL P OTENTIAL E NERGY KE max = GPE max Gravitational gravitational Gravitational
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?
E LASTIC P OTENTIAL E NERGY The energy stored in a deformed object, for objects that have the tendency to return to original shape
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.
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.
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
C LAY B ALL D ROP What energies are present? 1. Where did the energy come from? 2. What happened to the clay? 3.
W HAT IS D EFORMATION ? The transfer of KE to thermal energy causes a change in shape of substances (visible in soft substances)
S OUND Organized movement of particles – Turns to thermal energy once organization is lost
S OUND Organized movement of particles – Turns to thermal energy once organization is lost
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.
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
