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
Independent vs. Dependent Variable Variable
"I" Change it
"Depends" on what I changeThis 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?

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)

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 areFossilFuels ?
Renewable Energy vs.
Non-RenewableEnergy
What's so BAD aboutFossil Fuels ?
Let's Sort These: Move each to the left or to the
right

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
Heat / Energy Transfer Heat is transferred
throughDirect Contact
Heat is transferred throughWater or Air (Metal to the
Hand)(Flame through Air to Metal, through metalto Water)
Solar Cooking / Heating
How does this relate to
the Geenhouse
Effect ?
How can solar energy be collected for use in cooking?
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?
