NGSS Disciplinary Core Ideas: MS-ESS3.C, MS-ESS3.D
How can we generate electricity from cow poop? Below are discussion questions you can use in the classroom in conjunction with this video to engage your students in learning about this innovative renewable energy source.
Video Discussion Questions
1. How can cow poop get turned into electricity? What process does it go through?
2. What is methane? Why might we want to reduce the amount of methane that gets into the atmosphere?
3. How is cow poop used at the Straus dairy farm other than to generate electricity?
4. In the video, Albert Straus talks about creating and running a 'sustainable' dairy farm. What do you think a 'sustainable' farm looks like? In what ways is the Straus dairy farm sustainable?

KQED Clue into Climate: Methane-The Other Greenhouse Gas
Although there are natural sources of methane, most of the methane that is contributing to global warming is produced through human activities, such as landfill use and raising cattle. In this lesson from Clue into Climate, produced by KQED, students will learn about sources of methane and how methane affects climate.
