In this video, Phil used one of the world’s rare and strongest magnets to perform some cool experiments. What are magnets? A magnet is a material or object that produces a magnetic field that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc., and attracts or repels other magnets. Magnets have poles – when you put opposite ones together, they attract. But when you put the same ones together, they repel. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Could we find magnets powerful enough to repel each other and float Phil off the ground? You will find out in this video. Plus, watch magnets defy gravity all on their own.
Students will start to think in a far more creative, open minded way and soon they will start to create new ideas of their own.
This video satisfies the 3-PS2-3 and 3-PS2-4 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.
3-PS2-4. Define a simple design problem that can be solved by applying scientific ideas about magnets.
