Curated OER
Terrestrial Sequestration - Photosynthesis and Cellular Respiration
Students investigate how plants absorb carbon dioxide during photosynthesis. For this biology lesson, students differentiate photosynthesis and cellular respiration. They discuss the important role of plants in the environment.
Curated OER
Life or Death Food Chain Decision
Students discuss how energy is transferred to different trophic levels. In this biology lesson, students solve a theoretical problem and debate on a solution. They explain how energy is lost during cellular respiration.
Curated OER
Alcoholic Fermentation in Yeast
Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...
Curated OER
Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Breaking It Down
Seventh graders explain the mechanism of digestion. For this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.
Curated OER
Photosynthesis
Students conduct a variety of experiments on photosynthesis. In this biology lesson, students identify the factors required for the process to occur. They perform computerized experiments to test the amount of oxygen produced when plants...
Curated OER
Glucose
Young scholars conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
