The lab that they’re doing is talking about the ocean acidifying.you may ask yourself why the ocean is acidifying and it's because there is an ongoing decrease in the ph levels of the earth's ocean and it's caused by the uptake of carbon dioxide from the atmosphere. In the lab the students take a look at the shells and sit them in water that's been acidified over a week.
