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
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
Life or Death Food Chain Decision
Students discuss how energy is transferred to different trophic levels. In this biology instructional activity, students solve a theoretical problem and debate on a solution. They explain how energy is lost during cellular respiration.

Breaking It Down
Seventh graders explain the mechanism of digestion. In 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
Glucose
Students conduct various experiments on glucose. In this biology instructional activity, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
Curated OER
Yeast
Students study the characteristics of yeasts. In this biology lesson, students conduct experiments to measure yeast respiration. They discuss the favorable conditions needed for growing them.
