Water, Wind, Sunlight
Which part of an electric circuit conducts the flow of electricity?
wire
Which is a "FUEL"?
a. can be used to produce heat
b. Can be used as a medium to grow plants
c. can be used as a building material

a. can be used to produce heat
When you make a snowball, the snowball begins to melt and form a ball.
Why do your hands get cold?
EXPLAIN the energy transfer.
Heat from your hands transfers to the snow and melts it into a ball.
Which device transforms electrical energy into light and heat?
a. light bulb
b. blow dryer
c. fire
a. light bulb
Here are a few resources:
Coal, Water, Gasoline, Wind, Sunlight
Which are Non-renewable?
Coal, Gasoline
Which part of an electric circuit creates the current of electricity?
battery
Define "Renewable".
A resource that is abundant and won't run out any time soon. We can get more.
Tim warmed his mug before making his coffee.
Moby got a cold mug from the cabinet.
Explain whose coffee will get colder faster, and WHY?
Moby's coffee will get colder faster because the heat from his coffee will transfer to the cold mug to warm it up.
Tim's mug is already warm= less transfer of heat from the coffee.
Explain the energy transformation:
a clothes iron
Electrical to heat
Solar energy is renewable and clean.
What is one reason it is not used more often instead of fossil fuels?
It is expensive.
Which part of an electric circuit transforms the electrical current into light?
bulb
Define "Non-renewable".
A resource that is scarce. We would not be able to make more.
What will happen if you hold an ice cube in your hand? Explain the energy transfer.
Heat will move from your hand to the ice cube.
The ice will melt.
Explain the energy transformation:
a television
Electrical to sound, light and heat
A student says that using wind energy is more beneficial than using oil. He states:
1. Wind stations can produce electricity.
2. Wind will not run out.
3. Wind stations can be set up easily at low cost.
4. Wind does not pollute.
Which statement is NOT correct?
3. Wind stations can be set up easily at low cost.
Which part of an electric circuit can open and close the circuit as needed?
Which definition is correct for "radiate/ radiation"?
a. energy moves from one place to another by touching
b. energy moves from one place to another by waves
c. energy moves from one place to another by sinking
b. energy moves from one place to another by waves
A rolling ball hits a stationary ball. Explain the energy transfer.
The kinetic energy from the moving ball will transfer to the stationary ball making it begin to move.
Why can we use a microwave as an example of energy transformation?
It transforms the energy from electrical to heat and light.
Name 3 Fossil Fuels.
coal, oil, natural gas
Which component is not needed to make a complete circuit that creates light?
A. wire
B. bulb
C. switch
D. battery
C. switch
