Photosynthesis
Students recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data,...
Curated OER
Photosynthesis
Students are introduced to the process of photosynthesis. In groups, they test the effects of the lack of sunlight on plant leaves and compare the results with their hypothesis. They note the characteristics that plants and animals share...

Demonstrating That Light is Dissipated as Chlorophyll a Fluoresces
Students examine the concepts of light and chlorophyll. They participate in an experiment in which the chlorophyll shows as a red ring on the test tube. They answer discussion questions to end the lesson.
Curated OER
Do Plants Need Sunlight?
Students investigate whether plants need sunlight to survive. In this plant lesson, students experiment with plants to learn about chlorophyll that plants get from light sources.
Curated OER
Signs of Autumn
Second graders study photosynthesis and explore how chlorophyll is important to leaves and why leaves change colors in the fall.
Curated OER
It Ain't Easy Being Green!
Students explore the needs of plants. In this science lesson, students plant seeds and place one in a sunny spot and the other in a dark area. Students observe what happens.
Curated OER
Plant Growth - Light and Shade
Third graders conduct an experiment comparing plants. For this plant lesson, 3rd graders plant seeds and grow two varieties of plant comparing the light needed for it to grow. Students make predictions and record their observations....
