Environmental Differences
Young scholars observe and conduct an experiment to see whether differences in salinity (the environment) have an affect on the hatching rate and survival of brine shrimp.
Curated OER
Snail Observation Exercise
Young scholars are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.
Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
