Using Magnets

Activity Description:

Students will use magnets and design a series of experiments to explain how they work.

Materials:

2 magnets per student group, assorted objects (paper clips, wood blocks or match sticks with heads removed, plastic legos, wire, aluminum foil, marbles, rulers, etc.), and anything else students may request that you can easily get. Student sheet (see below) may be used or students can write on their own paper.

Time Needed:

40 to 60 minutes

Procedure:

1. Explain to students that they will be working in groups and designing an experiment based on magnets.

2. Show students the materials they have to work with and have them write a hypothesis like: If I test different substances, then some will be attracted to the magnet and some will not. Or: If I put two magnets together, then they will be twice as strong as one. Or: If I place magnets together and they attract, then I can place a substance in between them and they will not attract. Or: If I test the distance a magnet can attract a paper clip, then it will be the same for the North and South poles.

3. Have students write their hypothesis on the board and make sure they are not all doing the same one. If two groups are the same, have one think of something different.

4. Once they have decided on a hypothesis, give students some time to write their procedures for finding the answer to their hypothesis. You may wish to check these also.

5. Students should work with the materials and write down their findings in data.

6. When students are done, each group should report to the class what they found.

Scoring Guide:

1. Students write a correctly written hypothesis 5pts

2. Students write a procedure 5 pts

3. Students collect and record data 10 pts

4. Students present data to class and explain 5 pts

Title: Using Magnets

Introduction:

In this activity you will plan an investigation to learn about magnets. You can use the materials your teacher has provided and may even think of some other ones that are available. Try to think of a question about magnets and develop a hypothesis to start answering it. A hypothesis is written like this: If (I do something) then, (what do you think will happen?) Remember to be creative and think of as many things as you can. Talk with your group and decide on just one. After you write your hypothesis, plan a set of steps (procedures) to find out the answer. Write them down also. Then do the experiment and write down what happens (data). And, have fun!

Keisha was making an electromagnet in class and wondered if it mattered how many times the wire was twisted around the nail. What would be the BEST way for her to find out?

a. Look at someone elseÕs electromagnet to see what was used.

b. Try using the electromagnet with 20, 30, then 40 twists.

c. Try using one battery, then adding another battery.

d. Ask the teacher to find the correct answer.

ILO:

Two students in a class though that only copper wire could be used to make an electromagnet. Explain what would be the best way to prove or disprove their ideas.

Correct Answer:

Answers will vary, but one example would be for students to make one electromagnet with copper and another with a different wire. They should use the same number of twists on the wire, the same-sized nail, and the same-sized battery. They can then test to see if another type of wire will also make an electromagnet.

How could you find out if magnets worked to relive a personÕs pain?

Correct Answer:

Give some people magnets to place on the painful area and give other people non-magnetic replicas. See who thinks their pain goes away.

Title: How are Magnets Used?

Activity Description:

Students will research how magnets are used and make a list of at least 20 different uses for magnets.

Time Needed:

30 - 60 minutes

Procedure:

1. Students may work individually or in cooperative groups to find uses for magnets or electromagnets (textbook, internet site, library book, encyclopedia, etc.).

2. Students will create a chart or list showing ways magnets are used (Answers vary slightly, depending on source.)

3. Students will record their reference sources.

4. Class discussion time might be used for some of the most interesting uses of magnets.

Some answers include: all electric motors, battery-powered toys, TV picture tubes, audio and video tape players, copy machines, MRI machines, radar systems, etc.

Scoring Guide:

0 No attempt made

1 Up to five uses for magnets listed.

2 Five to ten uses for magnets listed.

3 Ten to fifteen uses for magnets listed.

4 Twenty or more uses for magnets listed.
