In this lesson, students investigate the effect of carbonic acid on razor clam shell mass to connect climate change and ocean acidification on the Oregon Coast.
Step 1 - Inquire: Students reflect on their own activity at the beach and learn about how beach recreation, ecosystem services, clamming, and tourism may be disrupted by climate change and ocean acidification.
Step 2 - Investigate: Students measure razor clam shells' mass before and after placing them in water acidified with carbonic acid.
Step 3 - Inspire: Students create a student action project to share their learning with someone outside the classroom.
