Janice VanCleave's 204 Sticky, Gloppy, Wacky and Wonderful Experiments

Published in 2002 by John Wiley & Sons, this volume is part of a long-standing series by Janice VanCleave, a former school teacher who became a prolific author of science education materials. The book was developed to demystify complex scientific concepts for elementary and middle school students by utilizing common household items, reflecting the pedagogical shift toward hands-on, inquiry-based learning that gained traction in American classrooms during the late 1990s and early 2000s.

VanCleave designed these activities to be accessible and engaging, often focusing on the 'sticky' or 'gloppy' properties of materials to capture a child's natural curiosity. The work fits into the broader Wiley 'Science for Every Kid' tradition, which prioritized clear instructions and safety. Critics and educators have historically received the series well for its reliability and its success in making laboratory-style experimentation feasible within a home or classroom setting.
