Description

In this game, you will use sonar to track marine animals and map treacherous ocean terrain. Between facts about sound waves, you'll encounter whales and dolphins who can help you move on to a quiz section. Show off your wave knowledge and earn bonus points for upgrading your submarine. Be careful, there is dangerous debris in the ocean that can damage your sub!

Instructions

Play through this interactive game to learn about Sound Waves. Suitable for Grade 10, Grade 7, Grade 8, Grade 9.

Main Concepts

When sound waves strike a barrier between two media, they reflect back and are perceived as an echo.

Waves transmit energy, but never transmit matter.

Waves can be generated when energy is transferred from one medium to another.

Wavelength is the distance between two peaks of a wave.

Wave speed is the distance a wave travels over a particular amount of time.

The speed of a mechanical wave corresponds with the material it is traveling through.

Surface waves travel along the boundary between two materials.

Sound waves travel out in all directions from their source.

Sound waves can refract when they transmit from one medium to another, causing them to change speed and direction.

Sound waves can interfere with each other constructively or destructively.

Sound waves can diffract and bend around a barrier between two media.

Sound waves can be absorbed when they transmit from one medium to another.

Sound waves are longitudinal waves.

Sound travels faster through materials with higher elasticity.

Sound travels faster through denser materials.

Sound intensity decreases with distance from source.

Seismic P waves are the same as sound waves.

Period is the time it takes for one full wave to pass a point.

Mechanical waves require a medium through which to travel.

Mechanical waves cause matter to oscillate.

Longitudinal waves cause matter to expand and contract in the direction in which the wave travels.

Kinetic energy exists in the form of sound energy when vibrations are transmitted as waves through materials.

In a sound wave, higher frequency corresponds with higher pitch.

In a sound wave, greater amplitude corresponds to louder volume.

Frequency is the number of waves that pass a point in a particular amount of time.

Amplitude is half the distance between the trough and peak of a wave.

A wave is a disturbance that transfers energy from one place to another.

A water wave is an example of a mechanical wave.

A sound wave is an example of a mechanical wave.

A seismic wave is an example of a mechanical wave.

Discussion Questions

Before the Game

How does sound travel? Sound waves are one type of wave. Can you name other types of waves? In this game, you will encounter dolphins and whales. Why were these two animals chosen for a game about sound waves and sonar?

After the Game

After a sound wave is generated, how can it change direction? What are the main parts of a sound wave? Describe each part and draw a diagram to represent each wave part. What are Seismic P waves? What geological event creates them? Which factors affect the speed of sound waves?
