Synopsis
This 12-minute video describes and shows how scientists analyze the gases trapped in ancient ice cores in order to learn about Earth's atmosphere in the past.
Students will learn that scientists have concrete evidence, demonstrated by the abundance of specific carbon isotopes in the ice, that global warming is being caused by burning fossil fuels and other human activities.
Ensure that students are familiar with the terms atom, isotope, and neutron.
Classroom Implementation
Use this video to introduce students to other uses of stable isotopes and radioactive isotopes, such as tracing molecules through food webs, medical testing, and tracing global cycles in the oceans and atmosphere.
Interdisciplinary Connections:
English Language Arts:
Students write persuasive essays on how people need to act swiftly in order to stop climate change. Students cite evidence from the video to prove that climate change is really happening.
