Introduction
Today we are going to be learning about waves and their properties. Waves can be many different things and you will be exploring energy waves and how they can transfer from place to place. We are going to learn about the different forms of energy and how it is transformed.
LET'S LEARN!!
Task
You are going to be working with your shoulder partner to complete this web quest to learn about waves. You will learn how energy affects waves and the different types of waves. We will complete a variety of activities to show the different waves.
1. Being sound waves using a speaker. (Non-virtual part of lesson)
2. A spring toy using energy to create waves ourselves. (Non-virtual part of lesson)
3. A container with water with a ball inside. (Non-virtual part of lesson)
4. A simulation along with an article to answer questions. (Virtual part of lesson after those are finished)
Process
Waves travel through a medium. A medium is a material through which a wave travel through. Media in which waves can travel through include gases (such as air), liquids (such as water), and solid (such as rope). In this lesson, students will conduct experiments and observe how waves travel through these media.
Station 1 (Preferably outside)
- Waves in liquids Materials: A bin, a ball and water. Fill 3 or 4 bins with water and let students disturb the water to make waves. Ask them to think about the following questions which the class will discuss at the end:
- What makes waves?
- What do waves carry?
- What patterns do they make? How many patterns can you notice?
- What carries waves? Ask them to put a ball at one end of the bin and make the waves. Let them observe what happens to the ball. Does it move or does it stay on one side of bin?
1) Two students hold a slinky at each end and stretch it on the floor. Do NOT over stretch the slinky.
2) Now, move one end of the spring back and forth on the floor. Notice the shape that the slinky makes and draw a diagram of it in your notebook.
3) Repeat step 2, increasing the rate (but not the distance) at which you move the slinky back and forth. Observe the waves you create. 4) After the students are done with the slinky, they should switch to using the rope.
5) Two students hold the rope at each end. One student should move it up and down. Slow at first and then faster.
6) What differences do they notice between the waves formed by the slinky and those by the rope?
-Set up a station of 2-3 iPads.
-Using the app “Audio Tool,” tell students to make different noises and sounds and watch what kinds of waves their noises make (They can scream and yell for this exercise) or Put rice or anything light on the plastic.
- Put some music on, turn it up as loud as it can go (ear plugs provided) and watch the vibration caused by the sound waves make the rice bounce up and down.
- Ask students to think about why that is happening.
Now you will conduct an investigation using this simulation. You will change the amplitude and frequency to see how this affects the wave and wavelength.

Fill in the graphic organizer as you change the amplitude and frequency:
https://phet.colorado.edu/en/simulations/wave-on-a-string
Explain what you saw the string do as you manipulated the frequency and amplitude.
Questions for thought:
Did the wavelength increase?
Did it decrease?
What makes the wavelength wider?
Evaluation
You have completed the quests so far, not it is time to see how much you have learned so far! You have read, completed investigations, and completed a graphic organizer that I have checked. Now it is time to see how much you have retained, please complete your assessment and click submit so I can grade it.
You on a roll! Keep it going!
Goodluck!
Conclusion
Congrats students. You have made it this far and have learned so much. I am unbelievably proud of you guys! You are now scientists and can share your knowledge with the world!

4-PS3-2: Energy and Waves
Performance Expectation: Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Clarification Statement: When energy is transferred it may change forms such as when light from the sun warms a windowpane.
Disciplinary Core Ideas: Energy can be moved from place to place by moving objects or through sound, light, or electric currents. (UE.PS3A.b)
