Subtopic Question

Brief Main-Idea Answer

What is a waterfall?

How does falling water get power?

-steep drop (cliff) in a river’s course that causes the
water to fall directly downward
-waterfalls get their power from gravity, the further
the fall, the more power

What is a waterwheel?

What were the early uses of water power?

-a wheel pushed by water to power machines
-grinding grain, irrigating crops, getting water to
villages, create iron, make paper, etc.

How is water used to make electricity?

What are dams and why were they built?

-water at the bottom of a dam turns the turbines
which cause the generators to create electricity
-dams block the water so that the water can be
released at a slow pace

VOCABULARY

• Generator is a noun

that means a
machine that makes
electricity. It
contains magnets
that spin. You can
see that the root
word is the verb
generate, which
means to make.

vocabulary

words

WORD FRAMES

electricity

noun
a type of energy measured

in volts

They have found ways to capture this energy
and turn it into electricity, or the power in our
homes and factories. (p. 5)

waterwheel

noun

type of machine with flaps
connected to a shaft that

turns gears

The simplest early device was a waterwheel.
This is a wheel that is pushed by flowing
water. (p. 8)

dam

noun
a manmade structure that
controls the flow of a river

A dam blocks the river so that lots of water
can build up. (p. 12)

reservoir

noun

a large body of water that
can be used as a source of

water for a town

The water that builds up behind a dam
creates a human-made lake called a
reservoir. (p. 13)

hydroelectric

adjective

power made from water

Today, the power of water is used to make
electricity. The plant that does this is called a
hydroelectric plant. (p. 14)

generator

noun
a machine that makes

electricity

When water spins a turbine, it turns a shaft
that is connected to a generator. The
generator is what makes electricity. (p. 16)

renewable

adjective

able to be created again

Because there is always sunlight, solar energy
is renewable, or capable of being replaced
by nature. (p 24)

Page 16, after: Wires inside the stator carry the electricity out of the
generator.

I can make a connection here. The text and the illustration here are
very similar to what we saw in the earlier section about mills. It looks
like the generator is very similar to the grinder that we might find in a
mill. So both rely on spinning, but a turbine generator has magnets
that are spinning and generating electrical charges because of their
movement.
