Ocean Acidification and its Impact on Marine Life

Learn about ocean acidification, its causes and effects on marine life. Conduct a simple experiment to understand how it affects pH levels in water and the reaction with shell fragments. Explore the importance of pH balance in our oceans.

  4. Ocean Acidification Work in groups of two. • Take a ziploc with water and a straw • Check the pH of your water (you can use pH paper too if you’d like) • Blow into the straw until you see a color change. • What pH is the water now? • What makes the pH change? • Place a shell/test fragment into the bag, any reaction? • Compare yours to the vinegar beaker. UNIVERSAL INDICATOR pH color • red/orange • orange • yellow • yellow/green • green • blue/green • blue/gray • violet
