Electromagnets
Engagement:

You have spilled your jar of steel paper clips all over your room. Rather than pick them up one
by one you decide to use a magnet. However, you don’t have a magnet. All you have is scattered
supplies like an iron rod, some wire, a battery. Then and idea strikes you. Is there a way you
could use electricity to make a magnet? Make a hypothesis about whether you think you can
make a magnet using electricity. How do you think it would work?

Exploration:

1. In your group of three go to
http://schools.bcsd.com/fremont/4th_Sci_Electricity_electromagnet.htm and scroll down
to “What is an electromagnet?” Read that section.
2. Scroll down and read the section called “What’s the difference between a regular magnet
and an electromagnet?” do not click on any other links.
3. Next go to http://www.sciencebob.com/experiments/electromagnet.php as you read think
about how you would make an electromagnet. Make sure to pay special attention to the
“How Does it Work” section.
4. Go to http://www.energyquest.ca.gov/projects/electromagnet.html read the “What You’ll
Discover” section.
a. What is an electromagnet?
b. How does it work?
c. Explain what you need to build a simple electromagnet?

Explanation:

hypothesis?
2. If you were to build an electromagnet what you think would affect its strength? How
could you get it to pick up more paperclips?
3. As a class we will watch and discuss this video [To further comprehension I could show
this short video where Dr. Ruiz has built a model and demonstrates the principle of
electromagnetism. Go to http://www.phys.unca.edu/demos/videos/demos_videos.asp
click on the video titles “Electromagnet.”

Elaboration:

1. Go to http://www.fossweb.com/modules3-
6/MagnetismandElectricity/activities/electromagnet.html.
2. Read the directions carefully before beginning.
3. Set the current on the side to DC (Direct Current)
4. Try to pick up as many iron fillings as you can.
5. What did you discover about the electromagnet? Take notes in your science notebook
about what happens when you change the voltage, gauge, winds, wire type, etc.
a. What settings did you have to have in order to pick up all 75 iron filings?
b. Did your electromagnet ever explode? Why do you think that happened?

Evaluation:

1. Given a word bank [Battery, wire, coil (solenoid)], have students label the parts of an
electromagnet (Science, 2010).
2. Hopefully we will be able to safely build a simple electromagnet and groups can plan to
try and try pick up a reasonable number of paperclips. They can experiment hands-on
trying to make their electromagnet stronger using different materials and techniques. At
the very end they can evaluate what their group did, why certain things worked or did not
work, and how their group functioned together.

Statement explaining how Web Quest addresses the objectives listed in the Standard
Course of Study for the content area for which it is designed:
The content area that I addressed was to explain how magnetism is related to electricity.
Here the students are learning that they can use electricity to create a magnet thus demonstrating
one level of their relatedness. This could lead into a lesson on how you can reverse the idea using
magnets to create electricity.

Explanation of how the WebQuest encourages higher levels of thinking:
In this WebQuest students are asked to hypothesis about the connection of electricity to
magnetism based on some prior information, and to explain their reasoning. They are also asked
to apply the basic knowledge they gain during this activity to making the most efficient
electromagnet and are asked to assess what makes the electromagnet stronger or weaker.

Explanation of specifically how the WebQuest explores content and process:

This addresses the National Science Education Strands content standard B. As a result of
the activities in grades k-4, all students should develop an understanding of properties of objects
and materials, light, heat, electricity, and magnetism, positions and motion of objects. In this
WebQuest students examine how electricity moves through wire and coils to create a magnetic
charge. They also learn about the position and placement of the materials in order to create an
electromagnet. They closely examine the connection of electricity to magnetism by using
electricity to create magnetism.
The Inquiry Process Skills addressed are observing, numbers, and communicating.
Observing using the data they have obtained to establish what would make for the strongest
electromagnet also observing what they do to the electromagnet applet and how it changes the
effectiveness. Numbers because they need to figure out how many times to wrap the coil, or what
voltage, etc. for the applet to be at. Communicating within the group and also during the class
discussion, what they learned and how they got their electromagnet to work the most efficiently.

Also students will address Language Arts Competency Goal 2: The learner will apply strategies
and skills to comprehend text that is read, heard, and viewed.
2.02 Interact with the text before, during, and after reading, listening, and viewing by:

   setting a purpose using prior knowledge and text information.
   making predictions.
   formulating questions.
   locating relevant information.
   making connections with previous experiences, information, and ideas.

Summary of appropriate accommodations for English Language learners completing the
WebQuest:

This vocabulary sheet will be included with the WebQuest.
Vocabulary
Magnet: Object that attracts iron or steel
Attract: Moving towards each other (Opposite charges attract)
Repel: Moving away from each other (Like charges repel)
Electromagnet: A temporary magnet that becomes magnetized when electricity flows
through it
Temporary magnet: A material that can be magnetized when exposed to a magnetic.
Current: Flow of electricity through a conductor
Volts (Voltage): A unit for measuring of electromagnetic force
Winds: the number of times the coil is twisted around the core
Gauge: thickness of the wire
Circuit: a path for the flow of electricity
Solenoid: Wire carrying electricity that has been wrapped into a coil
Since there are lots of complicated words with this concept this would benefit all students to
have the list, so they can fully understand the explanations given which use these words.
However, it would be especially helpful to ELL students. Also depending on their level of
English proficiency I could also write the WebQuest and vocabulary in their first language. This
site offers simplified vocabulary for this concept in Spanish:
http://www.fossweb.com/resources/vocab/Magnetism_and_Electricity_D_Sp.pdf. The partners
could help explain what the directions are, and it would be great if there was a partner who spoke
the student’s native language as well as English and could fully explain the directions to the
student. The electromagnet applet is easy to navigate once the student had the basic concepts
down.
Summary of appropriate accommodations for special needs students completing the
WebQuest:

Before delving into this WebQuest, as a class we will review the vocabulary and also the
concepts. Having the definitions and directions written down would be beneficial to students
with hearing impairments. Part of the review for all students would be going to
http://www.fossweb.com/modules3-6/MagnetismandElectricity/index.html and clicking on
“How Magnets Interact.” This is a very brief review of magnets. Listening to the review would
be helpful to a student with a visual impairment. If I had a student with a severe visual
impairment I could read the information on the sights into a CD recording and they could still
participate by offering suggestions to their group on how to make the electromagnet stronger
based on the information. Also if you go to http://www.fossweb.com/modules3-
6/MagnetismandElectricity/index.html and click on “Magnetism and Electricity Glossary” it will
read most of the vocabulary words for this unit to the students. Also they can listen to the video,
and the verbal explanation describes what is happening. Offering reviews helps all students, but
would be especially helpful to students with special needs. Also the incorporation of reading
about the electromagnet, working with one, and watching a real one in action, and ideally getting
to safely build one either individually or as a class helps give multiple means of engagement.
Working with partners also would be good for students with special needs since they could help
one another and provide examples of appropriate behavior. The hands on aspect of
experimenting with the applet, and then hopefully with the real thing should be affirming to
students with emotional issues, as well as being beneficial to all students.

For the gifted students (or anyone who is especially interested in this topic) they could work
ahead [3.02 Describe and demonstrate how magnetism can be used to generate electricity] and
explore a related concept through this activity:
1. If electricity can produce magnets do you think magnets can produce electricity? Why or
4. Was your hypothesis correct? Why?
5. Go to this site http://www.phys.unca.edu/demos/videos/demos_videos.asp click the
“Generator” video. Watch the short video demonstrating this concept of getting
electricity from magnetism
Also I took direct and alternating currents out of this lesson because explaining them is
complicated and would have taken away the focus. But if students were interested in it I thought
this was a good sight for learning about DC and AC:
http://www.pbs.org/wgbh/amex/edison/sfeature/acdc.html. Students could click back and forth
and compare what changes when they switch systems. Also I found the information on this page
to be on a more comprehendible level than in most places. And if confused students can click on
the parts to get details about what they are.
Grading rubric you would apply in evaluating student learning as per the Evaluation
