5/6 Center # 2: Electromagnetic Spectrum

Unit Essential Question: ______

______

Focus Question: How does the electromagnetic spectrum play a role in my life?

Task: Using the Chromebooks, you are going to participate in a self-guided online tour of the Electromagnetic Spectrum. As you go through the “tour,” you will add information to the Electromagnetic Spectrum you are creating.

Part I Background Information: Read the passage and answer the questions that follow.

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such asradiowaves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

1. What kind of electromagnetic radiation have you been exposed to today? ______

______

______

2. What kind of electromagnetic radiation have you been exposed to this year? ______

______

______

3. Do you think that any of the electromagnetic radiation you have been exposed to has been harmful? Why or why not?

______

______

______

______

_____ teacher check-in; ask for enough poster templates for everyone in the group.

Part II Start Making an Electromagnetic Spectrum Poster: Get the art supplies tub for table #2 and follow the directions below.

1. Title the Poster “The Electromagnetic Spectrum”.

2. Use your prior knowledge to fill in any of the blanks.

3. Refer to the grading rubric on the back of this page so that you know what your final Electromagnetic Spectrum Poster should have on it when it is completed.

_____ teacher check-in; take this paper and your poster template to the teacher

Part III Collect Data:You will watch a BrainPop video and talk an online guided tour. You will use the information that you collect from these resources to create a model of the electromagnetic spectrum.

1. Get a Chromebook assigned to your group representative ask the teacher to login.

2. Go to the blog and locate the online links for Center #2.

3. Watch Video #1: BrainPop: Electromagnetic Spectrum (the login is stout1, the password is falcon).

4. Use the chart under step 7 to write notes or collect useful information.

5. As a group, take the quiz. Record your score here: ______

6. At this point, everyone should log onto their own Chromebook.

7. Go to the blog and click on the link to take the self-guided tour (also under online links for Center #2).

8. Use the space below to write notes or collect useful information:

BrainPop Video / Electromagnetic Spectrum Tour

9. Use your notes/data to complete and color your Electromagnetic Spectrum Poster.

Electromagnetic Poster Grading Rubric:

Objective / Student Checklist / Teacher Checklist
The following electromagnetic waves are identified: radio, microwaves, infrared, visible, ultraviolet, x-ray, gamma rays
An illustration accompanies the identified electromagnetic waves: radio, microwaves, infrared, visible, ultraviolet, x-ray, gamma rays
Low wavelength, low energy, and low frequency are identified
Short wavelength, high energy, and high frequency are identified
The poster is colored, is neat, and is legible

_____ teacher check-in; take this paper and your completed poster to the teacher

Part IV Make Connections: Answer the following questions using complete sentences and a restate on your model.

1. Which type of radiation (on the Electromagnetic Spectrum) do you think is the MOST harmful to humans? Provide evidence from the self-guided tour, videos, and/or readings:

______

______

______

______

______

2. How do radio waves differ from gramma waves? Construct a Venn diagram model that illustrates and explains the differences between these two types of waves. INCLUDE the following terms in your model: frequency, wavelength, and energy:
