Question:
How does acid rain affects shells on the beach?
Hypothesis:
If you put vinegar, as a supplement of acid, on shells over a period of time then each time you add vinegar the weight and mass of the shell will decrease because the acid will breakdown the shell.
Methods:
First collect a three one to two inch shell. Make sure you have a scale and zero it out with the plate you will be using. Take one shell and place it on a plate that will allow vinegar to spread out and not pool up eventually submerging the shell. Measure the shell in the plate on the scale and record data. Measure 5mL of vinegar and pour it directly on the shell, wait three minutes. After three minutes, pour 15mL of water onto the shell to rinse the vinegar off. Place paper towels over the water and vinegar mix around the shell to absorb the liquids and dry the shell. Remove paper towels and throw away. With this shell now on a zeroed out scare with the plate on it measure the shell before you change anything about it. Take the plate with the shell in it off the scale. Then measure 5mL of vinegar and begin timing three minutes as you pour the vinegar onto the shell. After the three minutes is over pour 15mL of water onto the shell that has vinegar to rinse it off. Dump the water and vinegar mix around the shell out and dry the shell and the plate. Place both on the scale and record the weight. Repeat all steps 4 more times. Record all data.
Results:

Our results show that as we add vinegar, which acts as an acid, the shell begins to slowly deplete. After five intervals
