Dude, Let’s Catch Some Waves!

Physical Science10th grade

Introduction

Have you ever gone to a wave pool at an amusement park? You can hear the laughter and screams as wave after wave passes by, giving the people a wild ride. Have you ever been to the ocean and watched as people surfed the waves? This is an introduction to the wonderful world of waves!

Task 1• You will have 3 tasks to complete as a group into PowerPoint• 1. Create a fake twitter page for each of the 3 types of mechanical waves. The

bio should tell a little about the wave in general. The tweets should give a little information about the wave but translated into real life.• Ex. Transverse waves tweet: I came across a blanket today when a couple was trying to

shake the crumbs off after a picnic.• Ex. Longitudinal waves tweet: Me and an earthworm crossed the driveway today. It’s like

we’re joined at the hip.• Ex. Surface waves tweet: Hanging out at the beach today!

• The keywords crest, trough, compression, and rarefaction must be “tweeted”• Must have at least 5 tweets. Do NOT just list facts. Relate to real life.• There is a sample layout of the fake twitter page on the next slide

@WhicheverWaveCreate a text box. Biography of the wave goes here.

You can keep it short and sweet!

Task 2- How Often?

• Each individual is given problems dealing with frequency, wavelength, and wave speed• Task is due at time of submission of project.

Task 3- First 48

• Just like you, waves have behavior and there are 5 notorious behaviors! Your 3rd task is to profile these criminals!• 5 Criminals: Reflection, Refraction, Diffraction, Interference, and Standing

Waves• Profile includes:

• Picture or example• Description of the typical behavior so we can be on the lookout!

• At least 3 descriptions of each

Process• Create a Diigo account to manage the sites you have viewed that you may want to use

information on.• Here is a link to get started on creating your Diigo account

• http://help.diigo.com/home/get-started• The next step is to use the following sites to familiarize yourself with waves• What is a wave?

• http://www.acs.psu.edu/drussell/Demos/waves-intro/waves-intro.html• Define a mechanical wave?• What is a medium? Examples?• How do particles interact with one another to produce a wave?• List the three types of mechanical waves discussed in the text.

• http://www.ck12.org/book/CK-12-Physical-Science-Concepts/r1/section/5.22/Energy-%253A%253Aof%253A%253A-CK-12-Physical-Science-Concepts/

• http://www.physicsclassroom.com/class/waves/U10l1c.cfm• Relate each wave to real life. Waves occur throughout our every day lives. Pretend that

you are each wave. Tweet about what you do and where we can see you.

Process• We will go over task 2 during class but if you do not understand,

• For task 3, review your classroom textbook (17.3) and the following links for the behavior of waves.• What are the 5 behaviors?• What picture or image could represent this?• How does the behavior happen? What causes the behavior?

Evaluation• Task 1 (40 pts): Page 1 (picture 3pts, 5 tweets 6pts, biography 4pts)

Page 2 (picture 3pts, 5 tweets 6pts, biography 4pts) Page 3 (picture 3pts, 5 tweets 6pts, biography 4pts)

• Task 2 (20 pts): Practice problems sheet 20pts (individual)

• Task 3 (40 pts): Profile 1 (picture 3pts and description 5pts) Profile 2 (picture 3pts and description 5pts) Profile 3 (picture 3pts and description 5pts) Profile 4 (picture 3pts and description 5pts) Profile 5 (picture 3pts and description 5pts)

• Total: 100 pts

Conclusion

• At the end of this WebQuest, you should know:• What are the three major types of waves?• What are the components and properties of each type of wave?• What happens to the particles of the medium in each type of wave?• When the wavelength is changed, what happens to the frequency?• What is the major similarities and differences among the types of waves?• What are the different wave behaviors?
