We have always been captivated by the magic of magnetism. Why do strong magnets have such an attractive force? Why are certain elements magnetic, and others are not? With this video, students will be able to identify objects that are attracted or repelled by magnetism.
Do you have a toy that sticks together- something that has pieces that stick together or letters that stick to boards or refrigerators? Have you ever wondered why they don’t fall to the ground? it’s because they have magnets in them.
Jessie tried to make magnets stick to different objects but they only stuck to metallic objects. Magnets are only attracted to metal specifically iron. You can perform this experiment at home by collecting some items from around your home. Try to pick some objects that you think will attract a magnet, some objects that will not, and some you aren’t sure about. Make a prediction: What objects will and will not attract to a magnet?
This video satisfies the 3-PS2-3 requirement for third-grade science proficiency.
Students who demonstrate understanding can:
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.
