Photosynthesis lab methods

Methods:
 To do this lab you will ned the following items:
 3 beakers
elodea plant
bromothymol blue
microwave
ice
u.v. light
spectrometer
thermometer
First you will need to fill one beaker with bromothymol blue and heat it in the microwave for four minutes. Fill the second beaker with bromothymol blue and put ice in the beaker. The third beaker should be filled with bromthymol blue, at room temperature. After all of the beakers are filled with bromthymol blue, put the elodea plant in each beaker. Sit the beakers under the U.V. light and observe what happens after ten minutes.
