Fields Exist Between Objects NGSS Middle School Magnetism Lab Activity MS-PS2-5

This 2 day EYE-OPENING, FUN, and INTERESTING lab activity lesson challenges students to prove there is REAL IRON in cereal by designing and conducting their own experiments to prove magnetic fields exist between objects (magnetism)! It addresses the NGSS Performance Expectation through the Science and Engineering Practice of Planning and Carrying out Investigations: MS-PS2-5. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Lesson Overview. Students:

• Brainstorm, design, and conduct two experiments using provided materials to extract iron from cereal and collect data.
• Share results and reflect
• Conduct a third experiment using teacher provided dissolved cereal to extract the iron
• Answer conclusion questions by evaluating, reflecting, and connecting to magnetic fields as well as why iron is needed in your body!

Simple Materials Needed per group: strong magnet (such as neodymium), hand lens, ½ cup of dry breakfast cereal (Total® brand) in a small plastic baggie, small beaker/container of water

This resource includes:

• Student worksheets
• Conclusion Questions
• Teacher Tips
• Answer Key

It also meets the DCI: Forces that act at a distance (electric, magnetic, and gravitational) can be explained by fields that extend through space and can be mapped by their effect on a test object (a charged object, a magnet, or a ball, respectively).
