A Leaf Chad Resurrection
Photosynthesis Lab
Independent Variable - Why did we choose it?
Our independent variable we had chose was the color of the water. We used blue food coloring for the water, to see whether or not it had allowed the leaf chads to gain or lose more light energy to photosynthesize.
Control Average for the class - What did our results lead to on Day One?
Our class average led to about 12 minutes for 5 of the ten leaf chads to float to the top. It took our own leaf chads to float to the top at around 26 minutes.
The Experimental average of Day Two - How did they all line up?
The class average for day 2 was around 12 as well. We were not able to get all of our 5 leaf chads to get to the top, but the time it took to get 4 of ours took around 36 minutes (mainly because of what was being absorbed by the blue food coloring in the water.
Our Hypothesis
We had believed that if we had gotten the leaf chads put into a color most closely related to the color that the chads had reflected, it would slow down the rate of photosynthesis of the chads.
How did our new independent variable affect the new rate of photosynthesis?
Since the color of the water absorbed a lot of the same light as the leaf chads (the color of the water was blue), it had prevented the leaf chads from getting the same amount of light that it indeed needed to preform photosynthesis.
Any errors that our data could have had?
Some of the errors that we could have had would be:
1. Not effectively taking the oxygen and creating a vacuum and allowing the chads to have some oxygen left, which would help them rise a little easier.
2. Not putting the heat lamp as close as everyone else, it would have been hard to get the exact measurement as last time, or everyone else.
