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...

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...

Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...

Students explain chemosynthesis and photosynthesis using candy. In this chemosynthesis lesson, students work cooperatively to create a visual explanation of the chemical equations of photosynthesis and chemosynthesis.

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.

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...

Students explain the importance of chlorophyll in plants. In this biology activity, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.

Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

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.

Students 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.

Students discuss the importance of plankton in the ocean ecosystem. In this biology instructional activity, students identify the different types plankton by observing them under the microscope. They explain how plankton population...

Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Students describe the characteristics of algae. In this biology instructional activity, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.
