Waves 8th grade science

Introduction

We have been discussing Waves this week, and what Waves look like, do, and how they move. This Webquest will serve as test grade over the first set of standards S8P3 A-D.

Task

To learn more in depth knowledge and to demonstrate your mastery of Georgia state standards S8P4:A-D.

Process

Step 1.

Generate a Google Document to be turned in at the end of the assignment. You will use it for all the steps except for the final step.

Step 2. 

You will watch the attached video from Youtube, and as it plays you will list an example of light wave refraction and reflection that is given within the video. You will also write the difference between refraction and reflection. These answers will be added to your Google Document and should be labeled as "Step 2"

Step 3.

Go to Google classroom and complete the interactive PBS lesson over "Mechanical Waves", it will report your scores to me when you are done. Once you complete the lesson you may then move on to the next step.

Step 4. 

Once that is submitted go to the below link and watch the video over wavelengths. Answer the following questions on your Google document that you created and label it "Step 4".

Q1: What is the maximum Hertz that you can hear with your ear?

Q2: At what Frequency should you not be able to hear a sound if you are over 18 years old?

Q3: 1 Hertz equals how many cycles per second?

Q4: What is "Presbycusis"?

Q5: What could you use as a ringtone that only you could hear?

Q6: What Hertz is the most challenging frequency that is given to you in the video?

Q7: Write in at least one sentence one thing new that you learned in this video?

Step 5.

For this step you will go to the following link and read the article over wave frequency. You then will answer the review questions found at the bottom of the reading. Label the answers as "Step 5" in your Google Document and answer questions 1-11.

Step 6.

Go to the following website and answer the two questions below and label them "Step 6".

1. What are the two types of waves in this presentation.

2. Waves transport what?

3. What must a mechanical wave have to travel?

4. Wavelength is a measure of what two things?

5. What are the two types of mechanical waves? You can watch the video if you have forgotten.

6. What are electromagnetic waves?

7. Give three example of electromagnetic waves?

Step 7.

Go to your Google Document and CHOOSE THREE of the below activities to complete on your document. On the Doc label this "Step 7" then place your answers below. 

- Find one video that describes seismic waves and write a summary of what you learned in the video. Minimum of three sentences.

- Find an article over ocean waves, summarize the article and list facts that you may find interesting from in. Minimum of three sentences.

- Go to Google find an image of a Transverse wave, describe how you know it is a transverse wave. Do that by telling me two things that make it a transverse wave. Two complete sentences.

- Go to Google and find an image of a Longitudinal wave, describe how you know it is a longitudinal wave. Do that by telling me two things that make it a longitudinal wave. Two complete sentences.

-Go to Google and search,"Who discovered Seismic waves". Write a paragraph about how they discovered seismic waves, minimum five sentences.

-Go to Google and search,"Who discovered Sound waves". Write a paragraph about how they discovered sound waves, minimum five sentences.

Step 8.

For this step you will need to go onto Google drawing, once you do that you will search images you will insert an image of a transverse and a longitudinal wave. You will then label the following on the wave: Frequency (assume the wave was observed over one second), amplitude, rest position, crest (transverse), trough (transverse), rarefaction (longitudinal), compression (longitudinal), Wavelength, and what type of wave it is. Make sure that you label frequency in Hertz, and use your notes to help you complete the drawings. Once they are done go to Google classroom and submit them under "Waves drawings".

Step 9.

Go to your Google Document and answer the following questions and label it "Step 9". Make sure you type the question and your answer out completely, use your notes for the correct answers. If you use Google it may give you an incorrect wording for the answers, and I do not want you to get confused.

1. What are three waves waves change directions?

2. How does a wave change directions when it bounces off of a surface?

3. What are two types of interference?

 

Step 10.

For this step you will go to the following link and read the article over wave frequency. You then will answer the review questions found at the bottom of the reading. There are four total questions, label the answers as "Step 10" in your Google Document and answer questions 1 & 2.

Step 11.

After watching the attached video go to your Google Document and label "Step 11" and below it write in no less than THREE sentences what a Traveling wave is, and in THREE sentences write what a Standing wave is. Somewhere within your SIX total sentences the words Nodes and Antinodes need to be discussed.

Step 12.

On your Google Document label "Step 12" and below it answer these three questions using the attached article over new technology over Seismic waves.

1. What is ViBa?

2. How is ViBa helping reduce the destruction experienced by seismic waves?

3. ViBa could also be used to insulate buildings from ground waves such as? (list two examples given)

4. What is the practical issue with ViBa?

5. Does the latest research suggest that ViBa is a viable (good) option to protect lives from the destruction of seismic waves?

Step 13. Final Step,

For this final step go to your Google document. On your Google doc you have to write a short story about a time you have seen or experienced waves in your life. Whether that is ocean waves, seismic waves, waves from a cannon ball in the water, be creative and detailed. I am giving you an opportunity to be creative with your ideas and memories. During this short story mention at least THREE things about the wave that you observed. What I mean is maybe you noticed that the "crest" was higher than all the waves before it whipped you out on the beach. Another example would be that when I tossed my dog in the pond to teach it to swim I noticed the waves closest to my dog had "wavelengths" that were closer together than the ones farther from her. Be creative and be descriptive, TWO PARAGRAPHS with no less than 5 sentences. Although, I would love for you to go over. Complete your story and do not let it be short and without detail. This is the final step in your quest so please finish well.  

 

Evaluation

You will be evaluated on the percentage of questions you get right, along with activity completion.
