Water Bears & Pillbugs: Two Invertebrate Models That Offer Authentic Opportunities to Explore Research Methods in Biology

Abstract

Biological research entails myriad techniques and considerations for proper experimental design and data collection. The duality of field-based research techniques and laboratory protocols makes introducing this topic to high school and undergraduate college students a challenge. Two invertebrate models that serve as wonderful tools to support an inquiry process to balance techniques in the field and in the laboratory are terrestrial isopods and water bears. Both are easy to collect and rear, are relatively little-known species, and offer the chance for students to work directly with aspects of natural history, ecology, and biology. The 10-step process presented here offers an outline to follow in guiding students through a research cycle in the course of a semester (16 weeks).

Tardigrades as a Teaching Model of Learning

“…The American Biology Teacher contains several exercises on tardigrades. These exercises focus on the identification of different species in their natural environment, the collection process, and research methods (e.g., Rife, 2010;Shofner & Vodopich, 1993). The experiment we propose is the first publication that investigates learning in tardigrades.…”
