7. What are the definitions of these word? Draw a clear line connecting them to
their meanings.
current
To change one form of energy into another
battery
The complete path of an electric current around a series of wires and
connections. If there is a break, the current will not flow.
circuit
Electrical charge created when positive and negative charges are
imbalanced
transform
static
conductor
energy
The capacity or ability to do work.
A device consisting of one or more cells that can produce a direct current by
converting chemical energy to electrical energy.
a flow of electricity
A material that transmits heat, electrical, or other kinds of energy.
Power Generation (1.1)
8. The Ontario government and the Canadian government want to replace a
thermal-powered power plant that relies on burning fossil fuels. They would like
to locate a new cleaner power generating power generation plant near Brighton,
Ontario. What forms of energy generation would you recommend to the
government if they asked your input? Explain your reasoning.

Components of a Simple Electrical Circuit (3.6)
10. Create a diagram and explain the function of the components of a simple
electrical circuit. Use these words power source, load, and conductor.
11. Name 3 types of fossil fuels.
12. Why are fossil fuels bad for the environment?
13. What does non-renewable mean? Example.
14. What is the difference between a series circuit and a parallel circuit? Draw a
diagram to show. At the end of this test, demonstrate one of these circuits using
our batteries, fans, and light bulbs.
15. What types of power generation does Ontario use? Where do we get most of our
energy?
16. Which of these best shows a change from solar energy to chemical energy?
A. Evaporation of water
B. Heating of pavement
C. Photosynthesis in leaves
D. Formation of rainbows
17. A battery is placed inside a flashlight, and then the flashlight is turned on. The
chemical energy of the battery is changed into all of the following forms of energy
except—
a. Electrical energy
b. Heat energy
c. Light energy
d. Mechanical energy
18. Which type of energy change is occurring in these pictures?
e. Mechanical energy to chemical energy
f. Potential energy to kinetic energy
g. Chemical energy to heat energy
h. Solar energy to nuclear energy
19. This flashlight uses three different forms of energy.
Which of these shows the energy changes in the correct order?
a. Mechanical→Heat→Chemical
b. Heat→Chemical→Light
c. Electrical→Mechanical→Chemical
d. Chemical→Electrical→Light
20. Because burning fossil fuels creates much pollution, alternatives are being
investigated. What might limit the use of wind as a major energy source?
a. The strength of the wind varies from place to place and day to day.
b. Wind machines have huge blades to capture the wind.
c. Turbines and generators in the wind machine create electricity.
d. Wind power does not create pollution.
21. As the energy needs for Ontario increase, new sources of energy are required to
replace or supplement the non-renewable sources of energy now in use. Two
sources of energy that are renewable and available in Ontario are –
a. natural gas and wind power
b. coal and hydropower
c. petroleum and solar power
d. wind power and solar power
22. A group of people were concerned about a new coal-burning power plant that might
be built in their neighborhood. What is probably their main concern?
a. Burning coal produces more heat than burning wood.
b. The heat from burning coal can drive generators that produce
electricity
c. Burning coal produces sulfur dioxide, which contributes to acid rain.
d. There is more coal in the earth than there is oil and gas.
23. What type of energy does the windmill use to do work?
a. Mechanical
b. Nuclear
c. Chemical
d. Electrical
24. Fossil fuels such as gas, oil, and coal have what kind of energy?
a. Mechanical energy
b. Chemical energy
c. Electrical energy
d. Nuclear energy
25. Name four types of power generation in Ontario.
26. Which one generates the most power? Which one generates the least?
27. Thermal generating stations convert the
natural gas into
energy in coal, oil, or
energy. Thermal generating stations use
spin turbines. To create steam, water is
to
in boiler tubes that surround a large
industrial furnace that burns coal, oil, or
, depending on the type of
generating station. The steam is then transferred under pressure to the
causing it to spin and in turn spinning the
,
. The steam from the turbine
condenses back to a liquid, using cooling water from a lake, and is pumped back to the
boiler where it is reheated to continue the process
