Ocean Carbon Equilibrium
It’s been a rough half-century for coral reefs. Corals are threatened by polluted water, warmer-than-usual temperatures that cause bleaching events, disease, invasive species, overfishing, and direct destruction by humans. Since the 1950s, scientists estimate over half of the world’s coral reefs have disappeared.
Amid all of these problems, a new threat is emerging that may have implications far beyond coral reefs. As the amount of carbon dioxide in the atmosphere increases, the amount of carbon dissolved in the oceans increases as well. Dissolved carbon reacts with water to form carbonic acid. The excess of carbonic acid lowers ocean pH and makes it harder for marine organisms, including coral, to build their calcium carbonate skeletons and shells.
Students can learn more about this threat and explore possible solutions with the Ocean Carbon Equilibrium STEM Case, which is designed for high school and AP students. In this STEM Case, students will see how core chemistry concepts such as equilibrium and Le Chatelier’s Principle are applied in a real-world example. Hopefully this will inspire your students to think about how they can help preserve coral reefs in their own way!

Everybody's Talking About Gizmos
"Using Gizmos has had a positive impact on student learning. Gizmos allows them to dig deeper and manipulate variables to lead them to a higher-level depth of knowledge. There were plenty of students who had a ‘light bulb’ moment using a Gizmo!"- Teacher, Racine Unified School District, WI
"Textbooks have come and gone in our district at all grade levels, but what our teachers have been able to rely on for years is the quality of the product ExploreLearning is putting out with Gizmos."- Director of STEM Education, Hillsborough Public Schools, FL
"Teachers deserve a tool like Gizmos to empower students to conduct their own investigations, learn without reading lots of text but by doing lots of reasoning."- Teacher, Los Angeles Unified School District, CA
"I’m really a strong proponent of Gizmos in science because I have seen firsthand what it does in terms of engaging kids in labs. Gizmos really allow students to go deeper in terms of problem solving and critical thinking."- Assistant Superintendent, Miami-Dade Public Schools, FL
"I see more student engagement with lesson content when students are using Gizmos. Student grades have shown more understanding of the topics."- Teacher, Salinas Unified School District, CA
