Science of Biofuels
Summary
A complete biofuels unit built around a short video, covering how biofuels are made, where they work today, and the trade-offs around cost, land use, and the environment. Students move through bell ringers, vocabulary, a video quiz, two reading levels, real-world data analysis, multi-step math problems, a hands-on fermentation lab, and an exit ticket. Includes full teacher support: a teacher guide, answer key, and student lab handout. Works well for a high school energy unit, APES, or Earth and Environmental Science, with accessible entry points for middle school.
