Learn the science behind ocean acidification and its effects on ocean wildlife. Young scientists conduct a laboratory investigation that monitors the acidity level of water. While burning a candle, learners capture the carbon dioxide in the water and watch as the pH levels change. They then make a direct connection to the same process happening in our oceans.
