Summary Stack ring magnets on a stick, so that they repell each other and "float". Science content Physics: Motion and Forces, Newton’s Laws, Gravity (K, 2, 6) Physics: Energy forms, Conservation of Energy (1, 3, 4, 5) Science competencies (+ questioning + manipulation + others that are in every activity) Questioning/predicting: predicting (1 up), hypothesizing (7) Processing/analyzing: comparing observations with predictions (1 up) Evaluating: inferring (3 up) Lessons activity is in Magnet stations Magnet stations and more magnets/electromagnets Force stations Materials several ring magnets a skewer that the ring magnets can fit over Procedure Cap each end of a stick with 3 or 4 repelling magnets along the stick. Students free play with their own stick. Notes Cheaper ceramic magnets break easily when students free play. Grades taught Gr 1 Gr 2 Gr 3 Gr 4 Gr 5
