Earth's Atmospheric changes / COLOR / Photosynthesis
Understandings:
• Photosynthesis is the production of carbon compounds in cells using light energy.
• Oxygen is produced in photosynthesis from the photolysis of water.
• Energy is needed to produce carbohydrates and other carbon compounds from carbon dioxide.

Application: Changes to the Earth’s atmosphere, oceans and rock deposition due to photosynthesis.
Temperature, light intensity and carbon dioxide concentration are possible limiting factors on the rate of photosynthesis.
Skill: Design of experiments to investigate the effect of limiting factors on photosynthesis.
Water free of dissolved carbon dioxide for photosynthesis experiments can be produced by boiling and cooling water.
Aim 6: Hill's method demonstrating electron transfer in chloroplasts by observing DCPIP reduction, immobilization of a culture of an alga such as Scenedesmus in alginate beads and measurement of the rate of photosynthesis by monitoring their effect on hydrogencarbonate indicator are all possible experiments.
