Oysters are microscopic, free-swimming organisms during the first few weeks of life. Research is underway to determine how environmental factors, like water temperature and salinity level, affect the oyster's ability to change location in the water column during this critical stage of life. Students will determine the swimming speed and the effect, if any, of various environmental factors. [Lesson time: 90 minutes]
1. Make quantitative observations of larval behavior using metric units (mm, cm).
2. Calculate "swimming speed" of oyster larvae using the formula for velocity [V = d/t].
3. Identify patterns in data and the influence of variables.
