Creating Fuel From Things That Grow Around Us

Teacher Infomation:Lloyd Hilger

Hanover Horton Middle School

Unit OverviewThis unit will focus on the need for bio-fuels.  We will also look at the various types of bio-fuels and the pros and cons of each.  Students will also make ethanol in the classroom.

Target Grade Level: Seventh Grade Science

Lesson One: Biofuels

.Students will be learning what bio fuels are and the different ways that they can be produced. They will also be gaining an understanding of the benefits and drawbacks of each type.  They will also be looking at the need to use renewable resources such as bio-fuels.

Lesson Two: Climate Change

Students will be learning what bio fuels are and the different ways that they can be produced. They will also be gaining an understanding of the benefits and drawbacks of each type.  They will also be looking at the need to use renewable resources such as bio-fuels.

Lesson Three*: Enzymatic Hydrolysis

Aspen chips that have not been pretreated will not be broken down very much.  The flask that contains the wood chips and the chemicals will be placed in an incubator and heated to 50 C.  We will be comparing aspen that has not been pretreated with pretreated aspen.  The pretreated aspen should be more open because memicellulose was removed by pretreatment.  The open structure of  the wood more to allow the enzymes to be more effective, thus allowing more glucose to be formed.  There will also be a control flask that has the chemicals but no biomass.   All of the flasks will be tested for sugar (glocose) content every 24 hours.  This will be measured with a glucose meter.  Data will be recorded and graphed.

Lesson Five*: Distillation

Students will be part of an experiment in which the teacher will be running a distillation activity using the fermented product from a previous activity.  Students will be recording the boiling and vapor temperatures and times.  The teacher will collect at least two samples of the distillation products during this activity.  The samples will be weighed so that their densities can be determined.  From this data students will determine the % of ethanol in each sample.  These samples will then be used to make a 5% to 15% ethanol solution for our “Direct Ethanol Fuel Cell Fan”.  We will also be burning the samples in watch glass to compare the ethanol concentrations by observing the amount of water droplets that are left behind.
