- Biodiesel – an energy source made from plant oils
- Energy – the ability to move people and things
- Renewable resource – a source of energy that can be replaced
Interest Approach or Motivator
Iowa is the United States’ #1 producer of corn and soybeans. List some uses for the corn and soybeans in Iowa? Can you name any non-food or feed uses? Both of these crops can be turned into fuels for cars and trucks. Ethanol is made from corn and biodiesel from soybeans. It is likely that the fuel that powered the car or bus you rode to school today used ethanol or biodiesel.
- Cut out the Tassel to Tank information slips and randomize them.
- Provide students with background information about corn through the Renewable Energy and Agriculture PowerPoint or by using the suggested companion materials. Talk students through the processes involved in using field corn to produce ethanol for automobiles.
- Divide students into 13 groups. If 13 groups cannot be made, make as many as possible and give some groups two slips. Distribute one random Tassel to Tank information slip to each group.
- Give students 5-8 minutes to familiarize themselves with the information on the card and answer the card’s discussion question(s).
- One at a time, have a leader from each group come to the front of the class and present the information about their production step. Then, ask the student to place their step in the correct order, relative to the other steps already standing at the front of the class.
- Review the information with students and discuss the tougher questions from the Tassel to Tank information slips.

Did you know? (Ag facts)
- Iowa is the top corn producing state in the U.S.
- Around 40% of U.S. corn is processed into ethanol.
- Iowa is the top producing state of ethanol. The ethanol industry benefit local farmers and create jobs in rural communities.
- Visit a local wind farm, ethanol plant or biodiesel plant with students to learn firsthand about the creation of renewable fuels.
- Have students work in groups of 3-4 to create a video on either ethanol, biodiesel or wind energy that includes how it is created, connection to agriculture and the benefits of that specific energy.
- Ethanol can be made from other crops besides corn. Have students write a research paper on other sources of ethanol and the pros and cons of using that source.

Agriculture Literacy Outcomes
- Theme 2: Plants and Animals for Food, Fiber & Energy Outcomes
- Identify renewable and nonrenewable energy sources
- Theme 4: Science, Technology, Engineering & Mathematics
- Describe how biological processes influence and are leveraged in agricultural production and processing (e.g. fermentation)
- Identify science careers related to both producers and consumers of agricultural products
- Provide examples of how processing adds value to agricultural goods and fosters economic growth both locally and globally
