Impacts of Acidic Oceans on Shelled Organisms
Overview
Students will test the reaction of carbonate in different solutions of varying acidity to demonstrate how shelled organisms may be affected by an acidic ocean. Students will observe the reaction of a carbonate structure in different pH systems through experimentation. Students will use vinegar to represent acidic conditions of the ocean. Students will understand that ocean acidification weakens the calcium carbonate structures found in shells of marine organisms.

Performance Expectations MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. MS-ESS3-4: Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth’s systems. HS-ESS2-5: Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes. |
