Sources of Energy

Question 1

Wind Energy

Answer 1

Wind turbines turn generators to produce electricity.

Kinetic to Electricity

Question 2

Solar Energy

Answer 2

Solar cells generate electricity from sunlight.

Light to Electricity

Question 3

Hydroelectric power

Answer 3

A body of water is held behind a dam which is opened. The water falls through the openings turning turbines and generating electricity.
Potential to Kinetic to Electricity

Question 4

Geothermal Energy

Answer 4

Pipes are placed in the ground to absorb the heat from rocks in the Earth. This heat is used to generate steam to turn turbines.
Heat to Kinetic to Electricity.

Question 5

Nuclear fission

Answer 5

When the large nucleus of the uranium atom is bombarded with neutrons, it splits into two almost equal parts. This splitting is called fission.
This converts nuclear energy into heat energy. The heat is used to make steam which turns turbines to generate electricity within a nuclear reactor.

Question 6

Nuclear Fusion

Answer 6

Happens when two smaller nuclei of hydrogen isotopes combine to form a large nucleus.

Question 7

Nanotechnology

Answer 7

The science of the very small.
