Magnet Test Results and Predictions

Miss Patsy introduces a lesson on magnetism, focusing on what materials stick to magnets. She explains the composition of modern magnets and guides students to find magnets at home. The lesson involves predicting and testing which materials are magnetic, using items previously tested for electrical conductivity. The results reveal some surprises, such as a black rock sticking to the magnet, while expected items like copper foil do not. The lesson concludes with a reflection on the findings and encourages students to consider their own predictions and surprises.
