  • Get the Alaskan Snow pea leaves, biochamber, tin foil,  light sources, and glass balls(control group).
  •  Test the effect light has on photosynthesis with the light source and record the data. 
  • Test the effect the lack of light has on photosynthesis by covering the chamber with contents inside it with aluminum foil or towels. Record the data.
  • Repeat trials and record the results of the repeated trials.
  •  Clean up work area and put away materials.

This is shown by the lower amounts of CO2 show this. This also shows that the increase of CO2 represents when the plants are in a dark area, since photosynthesis is inactive.]]> 2016-10-19 01:16:55 UTC https://padlet.com/jmohn/c5lr332dvp65/wish/131668861 Conclusion jmohn https://padlet.com/jmohn/c5lr332dvp65/wish/131668862 Based on the results above, our hypothesis (When a light source is present, the rate of photosynthesis increases, but when there is no light, the rate of photosynthesis decreases.) is correct. The evidence to prove this is in the graph. The higher the line is along the y-axis of the graph, the higher the amount of CO2 is, and the lower the y-axis, the lower the amount of CO2. Possible sources of error include not covering the whole biochamber when testing photosynthesis in a dark place, and not stopping the observation of the photosynthesis rates at the exact same times.]]> 2016-10-19 01:16:55 UTC https://padlet.com/jmohn/c5lr332dvp65/wish/131668862 Graph jmohn https://padlet.com/jmohn/c5lr332dvp65/wish/131668863 2016-10-19 01:16:55 UTC https://padlet.com/jmohn/c5lr332dvp65/wish/131668863 Hypothesis/Prediction jmohn https://padlet.com/jmohn/c5lr332dvp65/wish/131668864 Hypothesis: 
    When light is present, the rate of photosynthesis increases, but when there is no light, the rate of photosynthesis decreases.

    Prediction: 
    If the rate of photosynthesis increases in the presence of light, and decreases rate in the dark, performing cellular respiration,  then when the plant leaves are under a light source, there should be less CO2 in the chamber, and when the leaves are placed and surrounded in tin foil, there should be more CO2 in the chamber.
