|1. Construct a basic setup like the one shown in your textbook on page 244.
2. Create a data table to record your measurements. Be sure to include a column for each color of light you will investigate and a column
for the control experiment.
3. Place the Elodea plants in the beaker, then completely cover the plants with water. Add some of the baking soda solution. The solution provides CO2 for the aquarium
plants. Be sure to use the same amount of water and solution for each trial.
|4. Conduct a control experiment by directing the lamp (without colored cellophane) on the plant and notice when you see the bubbles.
5. Observe and record the number of oxygen bubbles that Elodea generates in five minutes.
6. Repeat steps 4 and 5 with a different color of cellophane and record your observations.
7. Post your data below.
