MIT has developed Climate Science, Risk & Solutions, an interactive online textbook on climate change. It features clear navigation, extensive content, and engaging elements such as read-aloud sections, interactive graphs, and quizzes. Divided into sections like Climate Science, Change, Risk, and Solutions, it includes a glossary with hover-over definitions, additional resources, and a FAQ section. Users can also download the content as a PDF.
Note - If the dense text is challenging, consider using audio alongside the written sections for easier comprehension. Focus on the interactive parts and quizzes if you're unable to cover the entire site, maximizing engagement with the most interactive features.

Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic acid. Students then produce the reactions of the chemicals in a small reactor made from a plastic water bottle and balloon.

Through an overview of some of the environmental challenges facing the growing and evolving country of China today, students learn about the effects of indoor and outdoor air pollution that China is struggling to curb with the help of engineers and scientists. This includes the sources of particulate matter 2.5 and carbon dioxide, and air pollution impacts on the health of people and the environment.
Students observe demonstrations, and build and evaluate simple models to understand the …
Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect, the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers, themselves and the Earth. In an associated literacy activity, students learn how a bill becomes law and research global warming legislation.

This unit covers the processes of photosynthesis, extinction, biomimicry and bioremediation. In the first lesson on photosynthesis, students learn how engineers use the natural process of photosynthesis as an exemplary model of a complex yet efficient process for converting solar energy to chemical energy or distributing water throughout a system. In the next lesson on species extinction, students learn that it is happening at an alarming rate. Students discover that the destruction of habitat is the main reason many species are threatened and how engineers are trying to stop this habitat destruction. The third lesson introduces students to the idea of biomimicry or looking to nature for engineering ideas. And, in the fourth and final lesson, students learn about a specialty branch of engineering called bioremediation the use of living organisms to aid in the clean up of pollutant spills.

EARTH AND SPACE SCIENCE This short animated video is the first part of a two part series on carbon dioxide and carbon capture and storage. Part one explores where carbon dioxide comes from, the role it plays in the atmosphere, and the efforts that humans are making to control, reduce and mange carbon dioxide emissions. For Part 2, check out "Do you know what carbon capture and storage is?".
ABOUT THE SCIENCE There are many ways that plants benefit both humans and animals. Humans and animals breathe in the oxygen that is created by plants and in return they exhale, or breathe out, carbon dioxide. Plants then take in the carbon dioxide and release more oxygen. Carbon dioxide, also known as CO2, is a naturally occurring substance that is made up of carbon (C) and oxygen (O2). Both humans and animals exhale carbon dioxide into the atmosphere, but it can also come from decomposing bio-matter. Carbon dioxide is considered a greenhouse gas, which is to say it helps to control the Earth’s temperature by keeping thermal energy from the Sun in the atmosphere. Many of the things we do every day produce greenhouse gasses and it is important for us to control, manage and reduce the amount we put into the atmosphere. Too much or too little cause an imbalance in the Earth's temperature. Some things you can do to help reduce the greenhouse effect are practical and easy to put into use: • Reduce, reuse, recycle can help reduce the CO2 . • Take up walking and biking instead of using the car. • Use less hot water in the shower or the laundry. • Save on electricity. Use that “Off” switch. • Plant a tree every year you are in school or celebrate a special annual event by planting a new tree! Earth Day is April 22nd!
