Conclusion:
Ocean Acidification Pt. 1 - The longer you bubbled, the lower the pH got.
Ocean Acidification Pt. 2 - The control shell absorbed water which made the final mass larger than the original. The experimental dissolved more.
Ocean Acidification Pt.1:
The final results for the first bubble test were pretty plain and simple, stayed around 7, which is neutral. For control we were given 3 choices of what we wanted to try and we chose ice/cold water. That didn’t really turn out any different than the first test so overall it was neutral on the pH scale.
Ocean Acidification Pt.2:
The Low and High Exposure shells changed a lot more percentage wise but they had a lot more time where we only had 30 minutes. I think our shell would have the same outcome given a longer period of time. At the beginning the control shell had more of a mix of colors and not as much white as the experimental one. But it surprised me when it turned very iridescent and glossy after 30 minutes. Where the experimental lost most of the whiteness and started dissolving.
Error Analysis:
During Ocean Acidification Pt.2, I don’t think our final control shell was meant to be heavier than our initial but it was anyways. It absorbed some water which cause it to be slightly heavier.
