The perfect addition to classroom science centers, our hands-on activity labs give students an engaging way to explore physical science! Each lab comes with cards that walk students through exciting, skill-building experiments…plus all the materials needed to complete each one, and an informative guide. Children just display a card in the wooden stand, then follow the simple instructions to complete the experiment—and bring concepts to life! We’ve even included fascinating information on the back of each card that explains the science behind each experiment and how it relates to the real world. Complete set includes all 4 labs shown, for a total of 171 experiment pieces. The Magnet Activity Lab requires 4 “AA” batteries (not included); the Electricity Activity Lab requires 4 “D” batteries (not included). Each lab also available separately below. Topics include magnets, simple machines, electricity, and force and motion.
