HypothesisHypothesisNull Hypothesis: The algae will remediate carbon dioxide Null Hypothesis: The algae will remediate carbon dioxide but, not enough carbon dioxide will be remediatedbut, not enough carbon dioxide will be remediated

Alternate Hypothesis: The algae will remediate a significant Alternate Hypothesis: The algae will remediate a significant amount of carbon dioxideamount of carbon dioxide

PurposePurpose

The purpose of this experiment was to compare The purpose of this experiment was to compare different light and time intervals of photosynthesis different light and time intervals of photosynthesis to produce the most amount of Co2.to produce the most amount of Co2.

The Effects of Different Fluorescent Light Intervals on the Co2 Output of Chlorella

Chlorella Concentrations of 15ml Chlorella, 5ml AlgaGrow Medium, 480mL Fresh water. Two of these concentrations flow through 100ft of plastic tubing with 2 fluorescent 100

watt lights in the center as the light source.

The Algae concentration will be pumped around the light source in a course of 100 feet of clear plastic tubing.

Recording for differences in level of Co2 output for each time interval using the Glx Explorer in ppm (parts per million)
