Does a change in pH affect the growth and survival rate of aquatic plants?
Learners 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.
Curated OER
pH Change and Brine Shrimp eggs
Students determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine
shrimp.
Curated OER
Water Quality and Temperature
Pupils evaluate the effects of temperature changes on the metabolic rate of a clam. Conclusion questions are addressed which help students to process and articulate their experiences.

DOES A FLUCTUATION IN TEMPERATURE IFFECT THE GROWTH AND SURVIVAL RATE OF AQUATIC PLANTS?
High schoolers determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.
Curated OER
Temperature and Brine Shrimp Eggs
Students determine the optimal temperature at which brine shrimp eggs hatch and develop. They evaluate the changes, if any, which occur in a brine shrimp culture at various temperatures.
