In the Shells lab‚ we were to test the effect of pH on shell strength. The independent variable in this experiment is the type of liquid that we put the shell in and the independent variable is the shells’ strength. The first thing we did was get our materials and label the two shells.

experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that way‚ however
