Magnets are fun to play with. They are rocks or metals that create an invisible field around them. This field attracts other magnets and certain metals. A magnetic field is concentrated around the ends of magnets. These ends are called poles. All magnets have two poles: a north pole and a south pole. This video is all about magnets and magnetic forces.
Magnetic forces are non-contact forces; they pull or push on objects without touching them. You will also learn about the strength of the magnetic field. Magnetism works over a distance. However, the closer the objects are to each other, the stronger the magnetic force.
The visual aspect of the video will increase the student’s interest in the subject matter. It will also help them to retain information effectively.
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.
