Rusty had a bad cold; he had to stay in bed. When he could not find the bell to call his parents, his father showed Rusty how to attach wires to a dry cell to make his own bell ring. Rusty had fun. He even lit a light bulb using the same principles. The mechanics of electricity seem advanced for this early reading level and large type but this approach to science in story form might be just the thing in a community of children whose background has upped their interests somewhat. A challenge for highly scientific children, it might also be considered solely on its informational content for average third grade youngsters. Paul Galdone's pictures are explicit in the showing how to arrange a similar bell.
