Figure 2 is a bar graph comparing all the results of Andrew's trials. Each value for each trial is given. The overall trend that can be observed is that with each trial the further the strength degrades.

Figure 3:
Figure 3 is a line graph displaying the overall trend of the strength of the sticks. What is interesting to note is that at the beginning, the seawater immersed sticks are actually stronger than the fresh water ones, but as the days wore on, they declined faster.

Figure 4:
Figure 4 displays Michael's average results for each category after 4 weeks of experiment. The Ocean water seemed to have started off the same as the Fresh water, but after the second week, the Ocean water lost quite a bit of strength while the Fresh water popsicle sticks still remained consistent.

Figure 5:
Figure 5 shows the exact results of the different trials done throughout the month. The general statistics show that the Fresh water samples had some ups and downs from the first week to the second. The constant shift shows that the sticks have not really been fully affected by the water yet for they remain with fairly the same weight.

Figure 6:
Figure 6 displays the rate of decline in Michael's experiment. Similar to Andrew's experiment the gradual decline is shown and both the Ocean water and Fresh water lines are quire close to each other. In the first week, we saw that the Ocean water was actually slightly in better shape than the Fresh water having 2 out of the 3 sticks breaking with more weight than the Fresh water sticks.

Qualitative Observations:
Day 1:
Wood is clean looking, and very stiff. The wood has no blemish, and smells of wood and dollar store. Very rigid, dry to the touch and shows no sign of rotting.
Day 7:
Seawater: Feels hard to the touch, no visible difference from a week ago apart from the slight darkening in color. Smells slightly of salt and seaweed, to be expected. Dries particularly easily. Not bendable, shows no sign of rotting or bacteria infection.
Fresh: A bit mushy to the touch, slightly sticky. When pressed down, releases some water and loses volume. Could be the wood absorbing water and expanding due to "weathering" effect. Doesn’t really smell of anything besides water. Some areas have a bit more give than others, but overall still pretty sturdy.
Day 14:
Sea: Feels rigid but has a slightly soft exterior, slightly darker shade of brown with a slight hint of green. Smells strongly of the sea now with a hint of stink. It is easier to break than the fresh water sticks because of its rigidness.
Fresh: really moist to the touch, does have visible change in color, liquid has a swampy touch to it, smells like raw fish. Wood seems to be deteriorating, very puffy, extremely bendy, difficult to break in half. Resembles to stringed cheese when snapped in half for there would be strings of wood easily peeled off.
Day 21:
Sea: Starting to become quite soft, but far more rigid than the Fresh water sticks on the inside. Snapping the stick resembles snapping a glow stick, soft at first but then a hard snap. Smells off no longer fishy but a growing stench. Deep brown color, malleable exterior and some parts look to be wearing away.
Fresh: does not resemble stick as it is too moist and bendy, when broken, there are not individual strands of wood but instead resembles hairs stuck together. Behaves almost like a dry rubber stick, very bendy but when it breaks it’s not a clean break. Wood strands are very fibrous and soft to the touch.
Day 28:
Sea: Almost unrecognizable, a deep, almost light coffee brown look to the stick. Smells extremely strongly of the ocean. The snap is almost a clean break, but is also starting to become bendy with the middle hanging on by a bit.
Fresh: Color has not changed significantly, but looks dirty. Extremely moist, and very flexible. Very hard to get a clean break. The middle resembles hairs, and does not make a loud noise when snapped. It can be folded in half multiple times before breaking.
