Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.
Curated OER
Glucose
Students conduct various experiments on glucose. In this biology lesson plan, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
Curated OER
Earth Systems Science
Students perform experiments designed to grow plants and bacteria in a controlled environment. In this ecosystems instructional activity students investigate varying conditions for growing plants and bacteria.
