What do you think the bubbles are? ________________________________________ 2. How does light intensity affect oxygen production? _________________________ 3. Temperature and CO2 level a. A. How does temperature affect oxygen production? __________________ b. How does CO2 level affect oxygen production? ________________________ c. How does oxygen production relate to the rate of photosynthesis? _____________________________ ACTIVITY A: IDEAL CONDITIONS 1. In the Gizmo, what light intensity and CO2 level do you think will maximize the rate of photosynthesis? _____________________________________________________ ____________________________________________________________________________ 2. List the conditions for the ideal conditions you chose. Revise and repeat until you have found the ideal numbers. Temperature Light intensity CO2 level Oxygen production 4. Think and discuss: a. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold? ________________________________________________ ______________________________________________________________________ b. Why would it be hard to find the ideal CO2 level if the light intensity were very low? ____________________________________________________________ ______________________________________________________________________
