More than 200 daily science investigations actively involve kids in scientific inquiry into the life, physical, Earth, and space sciences. Meant for "soak" activities, these mini-activities (flash-card sized questions printed eight to a page and meant to be cut out) ask questions for review or research. An additional 16 "extended challenges" are full-page reproducible handouts that require more time because they challenge students to do research. Grades 4-6. Answer key. Illustrated. Good Year Books. 70 pages.
