Observing Water Moving Through Plants
We know plants assist in the water cycle, but how do plants get water from the ground into the air? Through a series of demonstrations or labs, scholars observe the movement of water through plants. They microscopically view the cells...

Microscale Investigations of Catalase Activity in Plant Extracts
Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

Investigating the Effect of Minerals on Plant Growth
How do different minerals affect the growth of plants? Budding botanists find out in a multi-week experiment that has them using solutions with specific mineral deficiencies. While there is a lot of preparation for the investigation,...
Curated OER
Photosynthesis
Students recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data,...
Curated OER
Population Growth
Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...

Graze Like a Cow
Students explore how a cow digests the grass they eat. In this science/math lesson, students compare the quality of forage. Additionally, students determine the effects of rangeland health on the production.
