Learning Goals
Students will be able to analyze pH data from simulated seawater samples to explain how ocean acidification changes marine chemistry.
Students will be able to interpret the carbonate buffer system in seawater to explain why ocean pH changes over time.
Students will be able to design and carry out a seawater simulation test to investigate how added carbon dioxide affects pH and shell materials.
Students will be able to evaluate evidence from case studies and regional marine data to explain impacts on shell-forming organisms, food webs, fisheries, and communities.
Students will be able to justify conclusions about ocean acidification using multiple pieces of evidence while distinguishing correlation from causation and noting anomalies.
Products
Ocean Acidification Investigation Notebook
A research notebook documenting each student's question, method decisions, pH testing data, annotated graphs, source notes, and personal analysis. It demonstrates individual mastery of the chemistry and evidence used to explain ocean acidification.
Ocean Chemistry and Community Case Study Brief and Poster
A team investigation report and public-facing poster that synthesize all members’ evidence into one defensible explanation of ocean acidification impacts and possible responses. It must show the team's methodology rationale, visuals, limitations, anomalies, and shared conclusions.
