Photosynthesis and Respiration

Students investigate the different pigments contained in green leaves by completing an experiment that strips away the chlorophyll and separates the pigments left behind.

Fourth graders discuss and identify the components of photosynthesis and the products of this process. They participate in a class discussion about the importance of oxygen, and in small groups act out the process of photosynthesis. ...

Fourth graders explore the interconnectedness of organisms in the environment and examine how different organisms obtain their basic needs. They discuss a frog's habitat and what is found in it. Students discuss the processes of...

In this photosynthesis and respiration worksheet, students will explore the function of the stomata on plant leaves Students will write the photosynthesis equation and label a diagram showing the movement of water, carbon dioxide, and...

Few people get to visit Alaska's Glacier Bay, and fewer yet go underwater to explore its kelp forest. Through this presentation, viewers get to do just that! In the process, they learn about the simple structure of kelp and the diverse...

A video workshop examining how the Sun provides energy for all living things beginning with the process of photosynthesis. Presents current scientific thinking about energy transfer through the food chain as well as ways to deal with...

Students smash plant parts and wait for visibility of chlorophyl to show why plants turn green. In this green plants lesson plan, students use acetone and filter paper for this experiment.

Students examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...

Students study chloroplasts, their structure and evolution.  In this photosynthesis instructional activity students experiment with polarized light and the production of chlorophyll.
