Shell Data Table 1
Purpose:
To test the effects of vinegar on mussel shells. Also, how carbon dioxide effects the shell of living organisms.
Procedure:
150mL of salt water for one beaker and 150mL of vinegar for the other. Then, in both beakers, we placed two mussel shells. The first mussel shell (Labeled H) was soaked in vinegar (Before we received it) for 720 mins, another (Labeled L) 360 (Also before we received it) mins, the third one (Labeled E) was going to soak in the beaker of vinegar for 30mins and the last one (Labeled C) was going to soak in the beaker of salt water for 30mins. After their soak, the shells were dried off and weighed (Weight can be found below). After weighed, we tested their tolerance to weight by placing textbooks on them until they broke.
Conclusion:
Doing this experiment helps students understand the effects of carbon dioxide. Mussels shells are vital because they provide protection, when carbon dioxide eats away at the shell, it makes the organism vulnerable. There are currently waters full of mostly carbon dioxide, so when creatures with shells or skeletons (Coral) are in that water, it decreases their chances of survival. Fortunately, living species like seagrass thrive in carbon dioxide contaminated waters.
