Introduction
Today, we will conduct an online investigation to observe wave patterns. You will be able to explore wave patterns, learn about wave properties, and describe cause-and-effect relationships of those wave patterns. You will explore wave patterns through a wave simulator and complete a cause-and-effect graphic organizer. I want you to think about how wave patterns can differ in amplitude and wavelength.
Task
With your partner, you will learn more about wave patterns. You will, also, learn more about cause-and-effect relationships of wave patterns, wave properties, and how waves can differ in amplitude and wavelength. Make sure you pay close attention to what you are learning and what you are observing when simulating a wave pattern. Once your graphic organizer is finished, you will answer questions to test your knowledge.
After you have completed the organizer, I have some questions for you to test your knowledge.
After you answer some questions, you will get the opportunity to choose a wave pattern and describe the wave pattern and describe the cause-and-effect relationship of the wave pattern.
Click here for your graphic organizer. Please make a copy of the organizer.
Process
What are wave patterns?
Waves are regular patterns of motion that can be made in water by disturbing the surface. Waves of the same type can differ in amplitude and wavelength. This difference is caused by energy. If there is little energy, the waves amplitude is smaller, and the wavelength is longer. If there is more energy, the waves amplitude is bigger, and the wavelength is shorter.

Amplitude is the height of the wave.
Wavelength is the spacing between wave peaks.

Evaluation
You have learned all about wave patterns and their properties. Now it is time to show me all that you have learned! You will show me what an expert you are at science by choosing 1 wave pattern to draw and label the properties. Then you will describe your wave pattern to me, basing your description off your knowledge of amplitude and wavelength. You may revisit the wave simulator site, but you may NOT work with someone. This is to be done completely by yourself.

Performance Expectation: Develop a model of waves to describe patterns in terms of amplitude and wavelength and to show that waves can cause objects to move.
Clarification Statement: Examples of models could include diagrams, analogies, or physical models using wire to illustrate wavelength and amplitude of waves. Examples of wave patterns could include the vibrating patterns associated with sound or the vibrating patterns of seismic waves produced by earthquakes. Does not include interference effects, electromagnetic waves, non-periodic waves, or quantitative models of amplitude and wavelength.
DCI: WAVE PROPERTIES Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; it does not move in the direction of the wave except when the water meets the beach. (UE.PS4A.a) Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks). (UE.PS4A.b)
