Introduction to Skeletons
This activity was selected for the On the Cutting Edge Reviewed Teaching Collection
This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are
- Scientific Accuracy
- Alignment of Learning Goals, Activities, and Assessments
- Pedagogic Effectiveness
- Robustness (usability and dependability of all components)
- Completeness of the ActivitySheet web page

This lab presents a specimen-based study of the different skeletal systems of animals and plants. The emphasis is on understanding the functional roles mineralized skeletons play in the major skeletonzied phyla comprising the fossil record, how skeletons grow and develop and what biological information they contain. As background for the main topic, students also learn about processes of biomineralization, the coelom as a hydrostatic skeleton and the Cambrian Explosion of skeletal invertebrates at the base of the Cambrian Period..
GLG 430 is a required course for students majoring in geological sciences and an elective course for biology majors. Graduate students can receive credit by doing additional work (research project).
