Grade Level: Grade 9
NGSS: HS-LS1-5. Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy. [Clarification Statement: Emphasis is on illustrating inputs and outputs of matter and the transfer and transformation of energy in photo-synthesis by plants and other photosynthesizing organisms. Examples of models could include diagrams, chemical equations, and conceptual models.] [Assessment Boundary: Assessment does not include specific biochemical steps.]
We know that photosynthesis is the conversion of light energy to chemical energy, and that the white light you see is a combination of colors, called the light spectrum. The following activity is a test to determine what the impact of different light colors has on the rate of photosynthesis.

Ward's® AP Biology Investigation 5: Cell Processes: Photosynthesis
In this investigation, the ability of plants to capture, store, and use energy from light for growth and reproduction is brought to life as students practice basic paper chromatography techniques to visualize pigments present in various plant leaves.
Ward's® Live Elodea densa Aquatic Plants
An excellent aquarium oxygenator, Elodea densa is great for teaching plant respiration, photosynthesis, and plasmolysis.
Ward's® Photosynthesis And Cell Respiration Lab Activity
With this lab, students learn about the connection between plant and animal cells by examining the interdependence of cellular respiration and photosynthesis in living organisms.
