This experiment demonstrates ocean acidification's impact on marine life. By placing shells in vinegar, observe how acidity affects calcium carbonate structures.
If shells are placed in vinegar, then they will dissolve over time due to the acidic conditions simulating ocean acidification.

Measure and record the weight of each shell.
Pour vinegar into the glass jar.
Submerge the shells in vinegar.
Seal the jar and place it in a location with a stable temperature.
Observe the shells daily for any changes.
Record observations including any visible dissolution.
Weigh the shells after 3 days and record the results.
Analyze the impact of vinegar on the shells.
The shells should show visible signs of dissolution after exposure to vinegar, simulating the effects of ocean acidification on marine organisms.

Handle vinegar carefully to avoid skin irritation, and wear gloves if necessary.
Create a visual timeline of your observations.
Use graphs to show weight changes in shells.
Discuss real-world implications of ocean acidification.
Prepare to answer questions about the chemistry behind the experiment.
Ocean acidification is primarily caused by increased carbon dioxide levels in the atmosphere.
Different shells may respond differently depending on their composition.
Yes, but vinegar is safe and effective for this demonstration.
