Beacon Lesson Plan Library
Magnetism in Action
Lisa Locklin
Santa Rosa District Schools
Description
The students recognize that magnetic force can act through a distance.
Standards
Florida Sunshine State Standards
SC.C.2.3.1
The student knows that many forces (e.g., gravitational, electrical, and magnetic) act at a distance (e.g., without contact).
Florida Process Standards
Information Managers
01 Florida students locate, comprehend, interpret, evaluate, maintain, and apply information, concepts, and ideas found in literature, the arts, symbols, recordings, video and other graphic displays, and computer files in order to perform tasks and/or for enjoyment.
Cooperative Workers
08 Florida students work cooperatively to successfully complete a project or activity.

Preparations
1. Familiarize yourself with the material in the textbook that covers magnetic devices.
2. Review the Lab Activity Worksheet and make enough copies for the groups.
3. Gather materials needed for the lab.
4. Review the video for showing either prior to or after the activity (optional).
Procedures
Note: This lesson deals with magnetic forces only.
1. Stimulate Prior Knowledge: Discuss with the students the characteristics of magnets and magnetic fields. You may want to ask the following questions:
*What does magnetic mean to you?
*Have you ever seen a material that is naturally magnetic?
*Do magnets have properties of attraction and repulsion?
*How are the poles of a magnet related to the magnetic fields?
2. Introduce the Lab Activity: Divide the class into groups of two. Hand out the Lab Activity worksheet. Review the procedure with the students. (See Attached Files.)
3. Lab: Ask the students to work in pairs to complete the lab activity. Students should collect and record data under the Data Table section of the worksheet.
4. Reviewing Concepts: After the students have completed the activity, ask them to complete the section of the lab activitiy worksheet labeled Analyzing and Drawing Conclusions.
5. Review: When the students have completed the lab, have them discuss their observations and answers to the analyzing and drawing conclusions questions.
Assessments
Assess the concepts taught in this lesson by using the students' work on the Lab Activity Worksheet. (See Attached Files.) Students may need corrective and defining feedback and additional practice or instruction before summatively assessing on this concept.
Extensions
Have a guest speaker discuss the process and procedure for magnetic resonance imaging (MRI).
