Your third option is to watch this Bill Nye the Science Guy video about Magnetism and take detailed notes.
What Needs to be Turned In For Option 3?
At least 1 page of detailed notes and summary about the video. Be sure to include all important vocabulary and topics.
- The video begins by explaining what a magnet is: a material that produces a magnetic field. Magnets have two poles, north and south, and like poles repel while opposite poles attract.
- The video goes on to discuss how magnets can attract certain materials, such as iron, nickel, and cobalt. This is known as magnetic attraction.
- The concept of magnetic fields is introduced, with Nye explaining how they extend out from a magnet and influence other objects around them.
- The Earth's magnetic field is also discussed, with Nye explaining how it is generated by the motion of molten iron in the Earth's core. This field is what causes a compass needle to point north.
- The video also touches on electromagnetism, the relationship between electricity and magnetism. When an electric current flows through a wire, it creates a magnetic field around the wire. This principle is utilized in devices such as electromagnets and electric motors.
- Key vocabulary terms include: magnet, magnetic field, pole, attraction, repulsion, magnetism, electromagnetism, compass, electric current.
Overall, the video provides a comprehensive overview of the principles of magnetism and their applications in everyday life.
