This Things of Science unit is heavy on the text (if a little light on the things). The booklet first gives a brief history of magnetism and then launches into 35 mini-experiments that are structured to take you on an understanding of magnetism.
The included reed switch might be the only thing a little difficult finding — the rest of the ingredients in the kit should be easily found in a middle-school science classroom.
