KIRKUS REVIEW

As per Experiments with Magnetism, a page or two of text followed by a double page of activities with guiding drawings. This immediately causes problems since on the first page we are reading about a current which we will create--the whole exposition being dependent upon the apparatus and activities not reached until the next pair of pages, which can be somewhat frustrating. The selection of activities to be performed is fairly pedestrian. We may make parallel and series circuits, make a small battery with two metals and a lemon, make an electromagnet with a nail and some wire--the usual things with hardly enough that is unique to bother about. We are instructed to hammer three pieces of wood together to make a stand from which to suspend a small piece of wire in order to observe the motion of a current-bearing wire in the field of a magnet. Again, we are told to carefully break a fuse (safety precautions given) to remove the fuseable wire, and to make a notch in this wire for an experiment. The reviewer dares all librarians to attempt this.
