Ocean Acidification

Interactive Earth Day Activity in ASL

Did you know your everyday activities can have an impact on the ocean? In this activity, Dr. Alicia Wooten and Dr. Barbara Spiecker show us how humans have had an impact on the pH levels of the ocean – also known as ocean acidification.

Watch Dr. Wooten and Dr. Spiecker perform an experiment showing how acids and bases can impact water. You can find the instructions below!

What You’ll Need
  • Cabbage Juice (Recipe)
  • Baking Soda
  • Vinegar
  • Cups
  • Straws
 How to Do it

Acids and bases have different impacts on the ocean. We can visualize this by mixing different materials with cabbage juice. If a substance is acidic, the cabbage juice will turn pink. If it’s a base, blue. 

  1. Fill three cups with an equal amount of cabbage juice
  2. In one cup, pour in a little bit of vinegar and stir.
  3. In another cup, pour in the baking soda and stir.
  4. If you have a straw, put it into the third cup and blow into it for 3-4 minutes.


Impact on the Ocean

You and your students have seen the drastic impact acidification can have on cabbage juice, but what does it mean?

In their next activity, Dr. Wooten and Dr. Spiecker show you how ocean acidification can impact marine life.
