- Lab & Experiment
- Graphic & Image
- Join to access all included materials
The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the results when compared with the ideal results — as well as the results from other fuel sources, both renewable and non-renewable.
