These open-ended task cards encourage older students to think and work like scientists. Task Cards measure 4 by 6 inches. The limited size of each card leaves less room to tell students exactly what to do, and therefore more freedom for students to follow their own experimental strategies. Thorough, thoughtful teaching notes accompany each card, and the task cards are also reprinted 2 to a page at the back of each book for easy photocopying.
