Curated OER
Evidence of Photosynthesis
Hands on science is the way to go! Learners conduct a lab experiment to help them explain how plants make food through photosynthesis. They test for the presence of starch in leaves using iodine solution and identify the basic things...
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
Terrestrial Sequestration - Photosynthesis and Cellular Respiration
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.
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
Chlorophyll
Students explain the importance of chlorophyll in plants. In this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.
Curated OER
Plant Transpiration
Students conduct various experiments to investigate plant transpiration. In this biology activity, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.
Curated OER
Color Change in Leaves
Students identify the different leaf pigments and colors. In this biology lesson, students perform chromatography to separate them. They explain how light affects green leaf colors and causes falling leaves in autumn.
Curated OER
Glucose
Learners 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
Plankton / Phytoplankton
Students discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.
Curated OER
Algae Experiments
Students describe the characteristics of algae. In this biology lesson, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.
