Students study the use of enzymes and microbes to produce ethanol biofuel. They investigate the ability of enzymes to break down starch under different conditions, and they determine the best conditions for using enzymes in ethanol production. Student teams brainstorm, design, build, and test an apparatus to capture and measure gas production during fermentation. They enter their engineered apparatus into a classroom competition, which can be scored using the design challenge scoring rubric. A grading rubric is also provided, facilitating assessment of each design team’s results. Team presentations allow students the opportunity to reflect on their experience and demonstrate their learning in creative ways.

Time Requirement
Teacher prep, 45 minutes. Engineering challenge, approximately 5 class periods.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.
