HOW DOES CARBON DIOXIDE CONCENTRATIONS AFFECT THE ACIDITY OF

WATER? BY JARED KLEINER & HARRISON FRIES

Background

Global warming

Importance of the oceans

Carbon Cycle

Excessive carbon

Hypothesis

We presumed that the more acid or dried ice that was added to the "ocean water" the more the shells would dissolve and or lose mass.

Materials6 mason jars (tight closing)

35 grams of shells for each jar

Sea Salt

Tap Water

pH testing strips

Sieve

Measuring cup

Procedure

Prepare water

Control Jars

Acidified Jars

Evaluating

Conclusion

Our data rearmed the fact that carbon dioxide emissions do cause damage to calcium carbonate based marine animals. The damage to marine life is only going to increase unless we make a change and humanity works to halt global warming.
