Curated OER
TE Activity: Bubbling Plants
Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

WET Science Lesson #5: Pass the Salt Please! (How Road Salt Affects Wetlands)
As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...
Curated OER
Cell Energy-Bubbling Plants
Students discuss the process of photosynthesis in plants and that oxygen is produced as a by product. They observe underwater Elodea plants "breathing" in a hands-on activity. After setting up the experiment, they observe the plant for...

DOES A FLUCTUATION IN TEMPERATURE IFFECT THE GROWTH AND SURVIVAL RATE OF AQUATIC PLANTS?
Students determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.

Serc: Investigating Discovering What Plants Need for Photosynthesis
This activity will be used prior to any direct instruction for photosynthesis. In this inquiry lab, students design and conduct simple experiments using elodea and Bromthymol blue to determine whether plants consume or release carbon...

Bio Topics: The Effect of Light Intensity on the Rate of Photosynthesis
Testing different amounts of light intensity, students conduct a photosynthesis experiment with the pond plant, elodea.

Pbs Teachers: Scientific American: Alien Invasion: Unwanted Travel Partners
Perform an experiment to observe inadvertent transfer of organisms when new fish are transplanted into tropical aquariums. Apply this knowledge to explain how alien species can rapidly destroy the established ecological balance in an...
