Scientists at major oceanographic research laboratories -- particularly the University of Maryland's Horn Point Laboratory and the Virginia Institute of Marine Sciences -- are currently engaged in a wide variety of experiments to understand the Eastern oyster (Crassostrea virginica) and the implications of various actions aimed at restoring its population. Using video clips of larvae in motion from laboratory research at Horn Point Laboratory, students will identify distinctive patterns of behavior and calculate swimming speeds under varying ecological conditions of temperature and salinity. This is the unit's core lesson. If your students already have an understanding of the Bay's oyster population and its larval stages, you could begin here. (Lesson time: 45 to 60 minutes)
1. Make qualitative observations of the "swimming behavior" of oyster larvae using authentic laboratory research data.
2. Emphasize the complexity of behavior in microscopic zooplankton.
3. Improve observational skills with repeated trials and interpretive materials (i.e.,"Behavioral Checklist.")
4. Communicate observations in written and diagramatic form.
5. Identify patterns in data and summarize observations.
