Teacher Background

Background Knowledge for Teacher
Waves in water:

The particles involved in waves move back and forth perpendicularly to the way the wave is going, but
don’t move significantly in the direction of the wave. In the image shown here, the circles represent the
movement of particles in deep water (A) and shallow water (B). The particles are moving up and down
while the wave is moving to the right (1). The particles ‘take part’
in the wave by bumping into one another and transferring energy.
This is why energy can be transferred, even though the average
position of the particles doesn’t change.

Possible Student Misconceptions

●Water cannot conduct electrical energy. Explain that while pure, fresh water does not conduct
electrical energy, salt water and most tap water and bottled water contain minerals that act as
conductors.

Do Now

The picture below shows a ball, a ramp, and four different blocks that Rita is using for an experiment.

Rita notices that when the ball hits a block,
both the block and the ball move. The metal
block moved the least. How could Rita
change her experiment to find out which
type of ball would have the greatest force
on the metal block? She could place the
metal block at the end of the ramp and ---

A. roll the same ball down the ramp, applying the same force each time.

B. roll different balls down the ramp, applying the same force to each ball.

C. roll the same ball down the ramp, applying different forces each time.

D. roll different balls down the ramp, applying different forces for each ball.

Make Meaning

How does the boat move?

The boat moves
when an object is
dropped into the
water to make
waves.

Energy transfers
through the waves to
the boat to make it
move up and down.

Energy Transfer by Waves in Water

Describe the transfer of energy from the ducks to the lily pad.

The duck movements transfer energy into water waves,
which then move the lily pad.
