This book of life science activities introduces a new experimental animal--the WOWBug, "Melittobia digitata"--that is commonly found in nature but has never before been used in the precollege classroom. It includes 20 activities and experiments for grades 5-12, that cover topics from basic orientation to ecological interactions, from physical science relationships and muscle power to the effects of diet on development. Investigations range from those that take only a small part of a regular class period to long-range studies that require several weeks to complete. The activities included focus on concepts developed by students through dynamic, inquiry-centered investigations rather than on the terminology embedded in a rhetoric of conclusions. Chapters include: (1) "WOWBugs and the Life Science Curriculum"; (2) "Observing Animal Behavior"; (3) "Structure and Function in Living Systems"; (4) "Change and Constancy; Growth and Development"; (5) "Sensory Responses: Experimental Design and Control of Variables"; (6) "Populations and Communities: The Interdependence of Organisms"; (7) "WOWBug and Mud Dauber Biology"; (8) "Teaching Aids"; and (9) "The Georgia WOWBugs Project."
