1. Welcome! CAPT Physical Science Review, part 1 In the next few pages, you will review the following concepts: 1.Independent vs. Dependent Variable 2.Energy & Energy Transformations

2. Independent vs. Dependent Variable Variable "I" Change it "Depends" on what I change This is what I alter during the experiment This is usually what I Measure as the Results Practice: If I want to determine what amount of sugar in my water would give me the fastest time to run 3 miles... What would the Independent Variable be? What would the Dependent Variable be? What if anything was Controlled?

3. Independent vs. Dependent Variable Variable "I" Change it "Depends" on what I change This is what I alter during the experiment This is usually what I Measure as the Results Practice: If I want to determine what amount of sugar in my water would give me the fastest time to run 3 miles... What would the Independent Variable be? Amount of Sugar What would the Dependent Variable be? Fastest time What if anything was Controlled? The distance the runners run (3 miles)

4. Beverage vs. Time Time (min) Amount of Sugar Which Variable Goes Where on the Graph? Independent Variable Dependent Variable

5. What is Energy? Energy is the capacity to DO some sort of WORK Some Types of Energy are… Solar (sun) Electrical Nuclear Wind Hydroelectric Chemical (fossil fuels) What are Fossil Fuels ?

6. Renewable Energy vs. Non- Renewable Energy What's so BAD about Fossil Fuels ? Let's Sort These: Move each to the left or to the right Solar (sun) Electrical Nuclear Wind Hydroelectric Chemical (fossil fuels)

7. Renewable Energy vs. Non- Renewable Energy Solar (sun) Electrical Nuclear Wind Hydroelectric Chemical (fossil fuels)

8. Energy Transformations Examples: - Solar Energy is converted into electrical energy - Electrical Energy is converted into light and heat energy When one type of energy is changed into another type of energy

9. Heat / Energy Transfer Heat is transferred through Direct Contact Heat is transferred through Water or Air (Metal to the Hand) (Flame through Air to Metal, through metal to Water)

10. Solar Cooking / Heating How does this relate to the Geenhouse Effect ? How can solar energy be collected for use in cooking?

11. Solar Cooking / Heating How does this relate to the Greenhouse Effect ? 1. Solar energy is attracted using some colored background 2. Solar energy needs to be trapped inside the cooker and transferred to the object How can solar energy be collected for use in cooking?
