Prior to beginning the lesson: (1) Cut out and laminate Vocabulary Cards for display in the classroom; (2) Photocopy The Power of Magnets (1 per student). (Allow 35-40 minutes for instruction time.)

Group Size: Small groups

Learning Objectives:

Students will be able to:

  • Describe how magnetic force can penetrate through an object.
  • Demonstrate the scientific process.

Vocabulary Cards (see attachment), The Power of Magnets (see attachment), magazine, small piece of wood, small piece of fabric, small piece of cardboard, small piece of aluminum foil, folder, shoe, magnets, paper clips, glass


  1. Display vocabulary card "magnetic force". Ask students: Who can remind us what this means?
  2. Tell students: We know that magnetic force is the pull of magnets towards one another. Do you think that magnetic attraction is strong enough to go through another object?
  3. Demonstrate for students. Hold up a magnet and a paper clip. Call two volunteers to the front of the classroom. Have one student hold up his hand and have the other student hold up the magnet and the paper clip on each side of the hand. Ask them: Does the magnetic force hold the paper clip through a hand?
  4. Tell students: We saw that magnetic force was not strong enough to go though a hand. Do you think that is the same for a magazine? A piece of wood? Aluminum foil? Give students time to share their predictions.
  5. Tell students: Today you will be working in groups to test magnetic force through many objects. Divide students into groups of three or four. Distribute one magnet, one paper clip, and The Power of Magnets to each group. Each student should have his or her own paper.
  6. Tell students: First you need to make a prediction for each object. Who can remind us, what is a prediction? Call on a student to answer. Tell students: Next you will test each object and record your results.
  7. Distribute one object from the list to each group. Rotate objects from group to group as students finish testing them.
  8. When students are finished testing all objects, direct them to answer the question at the bottom of the page together with their group.
Modifications: For students with special needs, provide one-on-one assistance as necessary.


Monitor students’ participation for understanding. Circulate classroom to ensure students are writing correct answers.
