9. You will now design and carry out an “Experimental Lab” using a variable that you select. Think about another factor you could test to determine its affect on photosynthesis. Set up a lab notebook page that lists your hypothesis, materials, procedures, data charts and conclusions. Ask your teacher for any extra

LAB #6 – Photosynthesis and Cellular Respiration Introduction In order to survive, organisms require a source of energy and molecular building blocks to construct all of their biological molecules. The ultimate source of energy for almost all of life on Earth is the light that comes from the sun (see the box on …

Floating Leaf Disk Photosynthesis Lab Introduction: Photosynthesis is a process that converts carbon dioxide into sugars such as glucose using energy from the sun. When light is absorbed by pigments in a leaf, the energy absorbed is used to incorporate the carbon dioxide into organic molecules in a process called carbon fixation.

In the first part of the lab, students learn how to measure the rate of photosynthesis indirectly by using the floating leaf disk procedure to measure oxygen production. Alternatively, they could explore how to measure the rate of photosynthesis using various probes interfaced to computers.

f. After the baseline test, students will write a hypothesis about what might increase or decrease the rate of photosynthesis. They will then manipulate the variables to test this hypothesis (i.e. adding baking soda solution to the water, or moving the light source closer). They will

Photosynthesis-Elodea Lab Photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar. Bromothymol blue is an indicator solution to those used to test for food nutrients. It starts as a blue solution in water, and turns yellow in the presence of carbon dioxide.
