• electrical grid

• source converter

• device converter

Which is NOT a source of energy?

• Fossil fuels

• Sun

• Sound

• Wind

What is energy?

• to change from one form to another

• what something can do

• to move something from one place to another

• the ability to do work, make things move or change

Changing energy to another form of energy, like electricity to sound or heat

• convert energy/converter
• energy
• function
• transfer of energy

Sun (solar), wind, water

• energy sources
• renewable energy sources
• The Design Cycle 
• design

Place a check beside all energy source converters:

• Solar Panel

• Power Plant

• Wind Turbine

• Motor

What form of energy goes into a device with a plug?

• Thermal

• Motion

• Electrical

• Nuclear

When electricity goes into a lamp what forms of energy come out?

• heat and motion

• nuclear and electrical

• light and heat

• sound and light

How can wind energy be use to power an electric system?

• Motion energy is converted to thermal energy.

• Motion energy is transferred to solar energy and then to electrical energy.

• Motion energy is created by solar energy.

• Motion energy is converted into electrical energy.

A town relies on water from a dam nearby to provide electricity. Explain the energy in

this example.

• Motion energy from the water is transformed into electrical energy.

• Motion energy from the water is transformed into sound energy.

• Electrical energy from the water is transformed into motion energy.

• Electrical energy from the water is transformed into electrical energy.
