Experimentation is one of the best forms of learning. When we allow children to explore and discover things, learning becomes more enjoyable and concrete. I placed a tray with several objects for the kids to test. My six year old served as the recorder while my 3 year old tested if the objects were magnetic or nonmagnetic.
As they experimented, we talked about whether the objects attracted or repelled. They learned that not all metals attracted, only steel and iron.
The next question was whether magnetism would work in water. So we put nails and paper clips in a glass of water and tested it. We also tested to see if magnetism would work through the glass. AJ was so thrilled at the results that he kept doing it over and over again.
E worked with the the Magnet Science kit which is a good extension for older children.
We concluded the lesson by reading Magnetic and Nonmagnetic by the World of Science.
