Capturing Carbon
This is a NOVA Science Now, 12-minute video which emphasizes the correlation between humans and our industrial production of carbon dioxide and the inability of plants to uptake that CO2 at a comparable rate. The program description reads: How did an eighth-grader’s science fair project inspire a new way to tackle rising levels of carbon dioxide in the atmosphere? Claire Lackner’s father Klaus, a geophysicist at Columbia University, had a brainstorm after he saw how Claire used an aquarium pump to capture carbon dioxide in the air. A decade later, Dr. Lackner is testing a product inspired by his daughter’s vision.
This short video begins with a brief introduction of carbon dioxide and oxygen exchange between living things, but it does not completely explain this interaction. As a result, this video should be used after direct instruction or as a guided inquiry instructional strategy for extension, so that students will gain an understanding of the relevance of our overproduction of carbon dioxide in the world we live. This video profoundly expresses how humans are contributing to global warming.
