This lesson is designed for use as a performance assessment after a unit on magnetic interactions has been taught.
It is also included in the Magnet Bundle of 3 lessons on TPT at:
In the Whole class activity, students place a compass around a bar magnet to “see” the invisible force field around a bar magnet.
In the Individual assessment, students conduct an investigation to find out how distance affects the strength of a magnetic force field. Students conduct 3 trials using 1, 2, and 3 bar magnets and observe the movements of a compass needle to determine the strength of the magnetic field of force around the magnet(s).
Students ask questions to determine the cause and effect relationships when there are magnetic interactions between two objects not in contact with each other by conducting a series of activities aligned to the Next Generation Science Standards. The three dimensions addressed are (1) the scientific practice of asking questions; (2) the disciplinary core idea of types of interactions; and (3) the crosscutting concept of cause and effect.
NGSS Grade 3-PS2-3. Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.
Student recording pages, rubrics for scoring, teacher background, Science Notes for Reading, photographs, and teaching tips are included in this download. Pictures are included to stimulate class discussions and provide clear directions for students. They also could be used for bulletin boards and centers.
