PRODUCT DESCRIPTION

This is a quick and simple lab to show the effect of increasing carbon dioxide levels and ocean acidification on sea life (specifically corals and other organisms with calcium carbonate shells or skeletons). In the first part of the activity, students perform an experiment to see how acidic conditions affect corals by soaking them in vinegar overnight. Then students read a passage about ocean acidification and how it affects reefs and other marine life. Students will use their data and the reading to write a C-E-R argument to explain how corals and marine life are affected by ocean acidification.


Materials:
-samples of coral
-Vinegar
-Cups
-Scale or triple beam balance.

This comes from my “Quick and Cl-Ev-R” series. Each activity is designed for students to practice writing scientific arguments with Claim, Evidence, and Reasoning based on real world data and experiences. Each activity includes a quick hands on activity or demonstration, data collection, and corresponding reading focusing on the scientific concepts presented in the activity.
