Who would have ever thought that a plastic bag, some water, and a few pencils would have adults screaming with fear? Learn how to poke holes in a plastic bag filled with water without spilling a drop. Phil also continues with the Levitation process. Watch out to see if he is going to be successful this time or not. He will also show you how to make your own magnetic chain. It may seem like magic, but it’s science and it’s fun!
The video also explores the interaction of a copper pipe with a magnet. The magnet induced a current in the copper pipe, which in turn produced a magnetic field. The direction of this current then opposed the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly. Neat, huh?
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.
