Formal Lesson Plan Electromagnets Theresa Voss EMA 400 Science and Math Curriculum & Methods Alternative Teacher Certification Program Marian College Instructor: Laura Maron Date: October 9, 2006 T. Voss Lesson Plan 2 Formal Lesson Plan: Electromagnets Grade Level: Fourth Grade Subject: Science Concept: Constructing an electromagnet Standards: A.4.3 Connect mathematical learning with other subjects, personal experiences, current events, and personal interests see relationships between various kinds of problems and actual events use mathematics as a way to understand other areas of the curriculum (e.g., measurement in science, map skills in social studies) E.4.1 Use computers to acquire, organize, analyze, and communicate information. Operate common computer hardware and software Use basic word-processing, graphics, and drawing programs Create, store, and retrieve electronic files D.4.8 Ask questions and make observations to discover the differences between substances that can be touched (matter) and substances that cannot be touched (forms of energy, light, heat, electricity, sound, and magnetism) Materials: D cell batteries (15), 4 inch nail (2 for each set of students), single-strand insulated wire (2 lengths for each set of students), paper clips, examples of electromagnets Objectives: Cognitive Objective: The student will be able to comprehend how an electromagnet works by the end of the lesson. Procedural or Performance Objective: The student will be able to construct an electromagnet by the end of the lesson. Dispositional or Attitudinal Objective: The student will be able to recognize electromagnets in his/her everyday life. T. Voss Lesson Plan Steps in the Presentation of the Lesson Introductory or Motivational Set: 1. Teacher will show students pictures of object from everyday life. 2. Teacher will ask what the objects have in common. 3. Teacher will define key terms: electricity, magnets, conductor, magnetic field. Outline of Steps in the Body of the Lesson 1. Teacher will demonstrate how an electromagnet works with one using an on/off switch. 2. Teacher will ask students what the advantage of using an electromagnet is. 3. Students will be partner according to the teacher’s preference. 4. Students will make predictions. 5. Students will wrap their two nails, one with red wire, 25 times, the other with white wire, 50 times, leaving about 15 inches on both ends. 6. Students will move through five stations, at the teachers signal, to test their magnets. 7. Students will graph their findings. 8. Partners will discuss findings and fill out their worksheets. 9. Students will type in their online Science journals. Concluding Set or Closure Activity 1. Students will discuss, as a group, their findings. 2. Students will fill out an exit sheet. 3 T. Voss Lesson Plan 4 Assessment of Student Learning Teacher will evaluate students’ understanding of electromagnets according to the results of their worksheets and their journal entries. Accommodations for Special Needs or Cultural Differences Gifted- Students will research an item that has an electromagnet and explain the basics of how the electromagnet works in that item. Physically Disabled- Students will be with partners who can provide assistance to those students. LD- Students will be provided with a modified worksheet and modified instructions.

Voss Lesson Plan Assessment: Electromagnet Experiment Name: ___________________ Number of questions correct (fill in the blank)- 4 points Made two predictions- 2 points Filled in graphs- 10 points, (5 for each graph) Entry in journal: date, name of experiment, explanation, conclusions- 4 points Your score: _________, (20 points possible) 5 T. Voss Lesson Plan Exit Slip Name: ____________________ 1. I understand how an electromagnet works? yes/no 2. I can make an electromagnet? yes/no 6 T. Voss Lesson Plan 7 T. Voss Lesson Plan 8 ELECTROMAGNET EXPERIMENT Name: ____________________ Partner’s Name: _________________ Directions: You will be creating an electromagnet. Remember, you are working with a partner and must share duties fairly. *Leave about 15 inches of wire at each end when coiling.* 1. Wrap the red wire around one nail, starting at the head, 25 times, tightly. 2. Wrap the white wire around the other nail, starting at the head, 50 times, tightly. There will be 5 stations. You will start at your assigned one and that move to the next one when the teacher signals you to do so. Test one nail at a time, red wire first. Attach the ends of the wire to the clips. See how many clips it can pick up. Remember to record your results on the graphs provided. Fill in the blank with the correct term. magnet electricity magnetic field conductor 1. The battery was the source of ____________________. 2. The copper wire was the ______________________. 3. A _______________ __________________ was created by the copper wire being wound around the nail. 4. The nail became a _______________. Make predictions. 1. Will the amount of batteries determine how many paper clips the electromagnet can pick up? Yes/No 2. Will the number of coils affect the amount of paper clips picked up? Yes/No Graph your results on separate charts on the graphs provided -- Chart 1 is for the red wire, Chart 2 is for the white wire. ***In your online journal include: the date, name of the experiment, how you made an electromagnet, and conclusions drawn from your graphs.
