Developmental Biology

(Complete Item Description)

Abstract:: In this course, the student will learn about the field of developmental biology from its origins to the present day. The course will take a look at historical experiments as well as modern techniques and the mechanisms of development. The student will follow a variety of metazoan organisms from their start at fertilization through the stages of their development and on to entire organismal and post-embryonic development, learning along the way about the molecular and genetic regulations involved in these processes. (Biology 310)

A Holistic Approach to Teaching a Laboratory, Using Sea Urchin Development as an Example System

(Complete Item Description)

Abstract:: This exercise uses brainstorming, writing, and oral presentation techniques within the framework of a laboratory to illustrate the basic principles of early development. In groups, students learn how to identify a good model system (the sea urchin), isolate its gametes, mix some gametes from each sex, and study the ensuing processes of fertilization and development. After being introduced to the basic techniques, student groups design their own experimental approaches to further analyze these processes.

Teachers and Students Investigating Plants in Space

(Complete Item Description)

Abstract:: In this activity students will grow "AstroPlants," a special fast-growing plant used in Space Shuttle microgravity experiments. They will become familiar with the growth process and life cycle of the plants and investigate the effects of gravity and light on plant orientation and guidance. Grades 5-12.
