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?
