Lesson plan introducing and exploring via hands-on lab the idea that raising acidity in the world's oceans is reducing the availability of carbonate, which impacts calcifying organisms such as oysters and sea urchins.

C-Learn is a simplified version of the C-ROADS simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

Dwelling on all the impacts of climate change can be overwhelming and lead to feelings of apathy or hopelessness; that is why it is imperative that we use a solutions-based approach toteaching about the topic. Climate change is caused by both natural and anthropogenic factors which lead to higher levels of carbon in the atmosphere. There are many solutions that can be employed to fix the root cause, mitigate damage, and to help us adapt to the changes that havealready occurred. It will take a global effort to take on this global issue. The best place to start is at a local level. There are many ways we can impact the planet in a positive way. One way is to decrease the use of fossil fuels which can lead to decreased global temperatures. We can also support policies or technology that will help us become more energy efficient. Many people all around the globe have started to enact these solutions. In this lesson plan, students will explore various solutions by simulating different policies in a model and watching a video about how people have started to tackle climate change within their careers.
