The Teacher's Packs are designed so that students have their own reader and materials. <br /> <br />Classroom materials consist of robust, non-consumable (when feasible) components designed for years of classroom use. <br /> <br />Extensions to the primary projects are practical as there are sufficient supplies for all. <br /> <br />The box is teacher designed for easy storage with compartments for convenient access to materials. <br /> <br />Internet animations, videos, interactives and quizzes complement the classroom experiments.Contents periodically updated by scientists and educators. <br /> <br />Supplemental internet materials allow students to progress at their own pace and to their own level of interest and detail.
