Why Are Plants Green?
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.
Curated OER
Tracking Ocean Ecology
Students look at the data maps given to them about how chlorophyll affects the algae blooms and make predictions about the harm they will cause. In this data maps lesson plan, students manipulate data sets from the website.

The Absorption of Solar Energy
Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...
Curated OER
Ecosystems and Remote Sensing
Young scholars obtain remote sensing data to compare and contrast global biomass data with global temperature data.
Curated OER
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
Plant Pigments
Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.
Curated OER
Falling Into Leaves
Students investigate why leaves change color. In this chlorophyll lesson, students examine how chlorophyll effects the color changes in leaves. Students take pictures of changing leaves, and create a class quilt showing the changes of...
Curated OER
Food Color Chemistry
Students investigate plant pigments in fruits and vegetables. In this plant pigments lesson plan, students observe the effects of pH changes on chlorophyll in one demonstration and they observe the effects pH changes on flavonoids in...
Curated OER
Obtain a visible spectra of chlorophyll a
Students become familiar with the concept of spectroscopy or the study of the interaction of matter with electromagnetic radiation. They prepare solutions and measure absorbance at different wavelengths. Pupils comprehend that mater and...
Curated OER
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
Photosynthesis and Respiration
Providing an overview of photosynthesis, this presentation would be a quick and easy way to go over information learned in class. This attractive and clear presentation would be a great way to kick off an exploration of photosynthesis.
Curated OER
Beat a Leaf
A simple, yet effective classroom activity is described in this resource on leaves and how they grow. The activity should lead pupils to discover how plants make their own food and what they need to survive. In the activity, they create...
Curated OER
Where Does the Green Go?
Students investigate why green leaves change colors in the fall. They press leaves and write a poem, create a chlorophyll leaf print, take a nature walk, and create a leaf shape poster.
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
What Do Trees Do for Dinner?
Students investigate how trees produce their own food. They examine chlorophyll cells with a microscope, analyze a cross section of a log, determine how old the tree was, simulate the distance of the roots, and create a play.
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
Soybeans: The Miracle Seed
Learners discover why soybeans are called the "miracle seeds." They make their own soynuts and share other foods made from soybeans. They create a bulletin board of soybean products.
Curated OER
Generate a Calibration Curve for Chlorophyll a
Students measure and graph the absorbance of light by chlorophyll at a specific wavelength versus chlorophyll concentration. They are given an unknown and determine its concentration from their calibration curve. Students become familiar...
Curated OER
Why Plants Are Green
Students discover the properties of chlorophyll in plants. In this plant biology lesson, students conduct an experiment to find where the chlorophyll in the plant is located. Students are split into small groups and study plant parts....
