This Why Should I Care?: Show How Increased Carbon Dioxide Makes the Ocean More Acidic activity & project also includes:
How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in marine environments. Then, they create an acid-base indicator and determine what changes in the solution when carbon dioxide is added and ultimately conclude that carbon dioxide directly affects the level of acidity in the oceans.
- Test other substances for acidity/alkalinity with the indicator
- Have learners research negative effects of ocean acidification on a specific marine organism
- Requires materials that may not be found in a typical classroom
- Engaging, hands-on activity holds students' interest
- Indicator is great to use in a variety of science applications
