Purpose:
The purpose of this lab was determining the effect of surface area on the beets ability to interact with the environment. Three similar sizes of beets were assigned. Each beat was cut up into different sizes as one large piece, two smaller pieces and eight tiny pieces. All three different slices of beets were placed in their own containers and tested.
Observation:
While the lab was going on, it was noticed the tiny pieces of beet were doing the best while the big piece of beet was not doing as well. The smaller the pieces of beet, the faster the water turns red. At the end of the experiment the tiny pieces of beet did the best while the huge piece of beet did not do as well. The tiny pieces of beet made a very bright red color while the big piece did not add much red, there was a bit of red, just not too much. The big piece of beet made a very watery red. So in conclusion with the experiment the bigger piece of beet had less surface area and could not did not interact with the environment as much as the smaller pieces of beet did.
Analysis:
As more pieces are added, the data grows smaller. The smaller the graph goes, the more pigment it has. In the graph you can see with sixteen pieces of beet it goes just over 90. While the once piece of beet has a really high bar, showing it does not have a lot of pigment as compared to the smaller pieces.
Interpretation:
The bigger pieces let out less red pigment and the smaller pieces let out more red pigment. The smaller pieces let out more red pigment because there is more surface area on the smaller ones. While the bigger piece of beet one has more volume. The red pigment is mostly skimmed off the out side of the beet. So when the beat is cut up it has a larger surface area, giving out more pigment. The volume does not matter as much as the surface area matters. The volume is just how much is inside. That does not matter in the case of this experiment because the pigment is
