QUESTIONS

Why are some sounds
louder than others?
Why do some sounds have
a higher pitch than
others?
Sounds start as vibrations in
materials. The waves spread from
the source in all directions.
How do animals use sonar
to detect obstacles?
Sound can be modelled as a
longitudinal wave, where the
vibrations travel back and forth, in
the same direction as the energy.


Evidence
How do sounds travel?
Waves are a powerful model for
explaining properties of sound,
including reflection (echoes).
A
I can answer…
What makes sounds?
Sound carries energy, and this can
be transferred to other objects.
F
Drummer
SKILLS
S
I can remember that…
Sound cannot travel through a vacuum.
Amplitude is a measure of the height of a wave.
The frequency of a sound is the number of
vibrations per second. It is a measure of pitch and
has the unit hertz (Hz).
The human hearing range is about 20–20 000 Hz.
The wavelength is the distance between peaks of
the wave.


I know how to…

Use a diagram to explain how sound vibrations
spread out from their source and also reflect.
Create charts, maps, diagrams or graphs to make
arguments easy to follow.
Draw and interpret wave diagrams showing
wavelength, amplitude and frequency.


Suggest scientific reasons for results that are not
consistent with the rest of the evidence. (R)

Suggest an alternative conclusion to the one that
I drew, which is also consistent with the data, and
compare which is more likely. (R)
Noise is unacceptable sound. (W)
Scientists use two kinds of data – primary data is
what you have collected yourself; secondary data
is that which comes from another scientist. (R)
L
Draw a conclusion, identify the evidence that
supports it and suggest a scientific explanation for
the outcome. (R)

What makes different
coloured lights?
Waves are a powerful model for
explaining the properties of light,
including reflection, changing
direction in different materials
(refraction) and spreading out
around obstacles (diffraction).
A
U
How do we see things?
Light comes in different colours,
which combine to make white
light.

How can light be made to
change direction?
How can we create
dazzling lighting effects?

problems?

How can we make an
exciting toy using light?
Use ideas about waves to explain how light
reflects, refracts or diffracts.
Use ideas about light to work out how to correct
specific sight problems.
Use ideas about waves and reflection or
refraction to design or adapt a device that uses
light or sound, and explain how it works.
