Students investigate how plants absorb carbon dioxide during photosynthesis. In this biology lesson, students differentiate photosynthesis and cellular respiration. They discuss the important role of plants in the environment.

High schoolers 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.

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...
