Photosynthesis Virtual Lab http://www.kscience.co.uk/animations/photolab.swf (search for "kscience photolab") This virtual lab allows you to study the rate of photosynthesis. You will be able to manipulate 4 potential variables in this simulation: amount of carbon dioxide, light intensity, color of light, and temperature. In this simulation you can directly measure the rate of photosynthesis by counting the number of bubbles of oxygen that are released. Choose one variable and design and experiment that would test how this factor affects the rate of photosynthesis. Remember, that when designing an experiment, you need to keep all variables constant except the one you are testing. Collect data and write a summary of your findings that includes the following: 1. What is your experimental question? (What are you testing?) 2. My hypothesis is: ______________________________________________________________________ ______________________________________________________________________ 3. Data Table 4. My conclusion is: ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ 5. Did your conclusion support or reject your hypothesis?
