Bioenergy Lab Series

High School Undergraduate
Investigation Unit
This video provides an overview of the Bioenergy Lab Series.

Growing demand for oil, geopolitical concerns, and social and environmental pressures are pushing the transition from imported petroleum to renewable liquid fuels, with biofuels planned for a major portion of the nation’s future energy. 

Meeting future biofuels’ demand will require a trained workforce able to provide the engineering and scientific research needed to operate existing biorefineries and the education of future generations of scientists. Universities, technical colleges, and high schools will need to educate workforce in these areas, but since this is a relatively new domain, limited teaching resources are currently available to instructors.

To help fulfill this need, we created twelve bioenergy lab activities. We designed these materials to augment existing classes or as a stand-alone bioenergy lab class. We also designed these labs to be low-cost to maximize the number of students that can participate in each activity.

We assessed the labs based on evidence of direct student learning outcomes (i.e., has the student learned the material/concepts?) and indirect student learning outcomes along specified dimensions. The direct student learning outcomes were assessed via the faculty using designed quizzes and reports to demonstrate knowledge of the concepts taught through the lab exercise. Indirect student learning outcomes were assessed through a custom-designed survey focusing on students’ perceptions of the following seven dimensions: Designing Laboratory Classes & Experimental Investigations, Expectations and Enthusiasm, Lab Pace & Lab Materials, Interest in Renewable and Sustainable Energy, Opportunities for Discussion, Knowledge and Learning, and Connections to Other Fields. A link to a summary report of the indirect learning outcomes is provided here.

All Bioenergy Lab Series Activities

Applying Spatial Information to Biomass Management

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will become familiar with the Biofuels Atlas, a web-based Geographic Information System (GIS) that contains spatial information related to biomass and biofuel pr

Size Reduction

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will become familiar with biomass size reduction, an important processing step in biofuel production.

Densification and Quality of Densified Biomass

Bioenergy Lab Series | Undergraduate, Nonformal

In this lab investigation, students will become familiar with densification, a process used to increase the density of biomass to facilitate its use as a biofuel.

Proximate Analysis of Biomass

Bioenergy Lab Series | Undergraduate, Nonformal

In this lab investigation, students will become familiar with the basics of proximate analysis of biomass.

Biomass Carbohydrate Composition

Bioenergy Lab Series | Undergraduate, Nonformal

In this lab investigation, students will measure the carbohydrate contents of biomass types as percentages of total mass.

Biomass Pretreatment for Fermentation

Bioenergy Lab Series | Undergraduate

In this lab investigation, students will perform an acid hydrolysis to convert cellulose from biomass into glucose for fermentation. This process is also known as saccharification.

Fermentation

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will convert simple sugars to ethanol.

Distillation of Ethanol

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will become familiar with the distillation process using a simple distillation column under the context of ethanol purification.

Anaerobic Digestion

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will become familiar with anaerobic digestion of a waste stream.

Combustion

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will employ the methods of calorimetry to approximate the amount of energy contained in a selection of biomass types and other food items.

Biomass Pyrolysis

Bioenergy Lab Series | High School, Undergraduate

In this lab investigation, students will become familiar with pyrolysis, a method to fractionate biomass is split into solid, liquid and gaseous components under the influence of heat only.
