2 Race to Algae-based Biodiesel Heats Up Agricultural Literacy Directions: After reading the article, determine the BEST answer for each question. Write the letter of the BEST answer in the blank provided. 1. According to the article, the main biofuel crops currently available are A. algae and forest products B. soybeans and corn C. switch grass and corn D. wheat and corn. 2. Why has there been a negative attitude toward biofuels? A. The use of biofuels has been blamed for an increase in air pollution. B. Biofuels are not refined in the United States and do not contribute to the U.S. economy. C. The use of biofuels is blamed for higher food prices and deforestation. D. Biofuels come from nations known to support terrorism. 3. Before algae can become biodiesel, it must first be changed to A. ethanol B. hydrogen C. carbon dioxide D. oil 4. Algae byproducts that aren t used in making biodiesel can be used for A. renewable energy B. animal feed C. fertilizer D. alcohol 5. How is Solazyme s processing method different from that of other companies developing algae-based fuels? A. Solazyme uses a fermentation process. B. Solazyme uses photosynthesis rather than fermentation. C. Solazyme recycles the water taken out in the drying process. D. Other companies are operating their business on more acreage. 6. Based on information in the article, which of the following areas would be best suited for growing algae as a fuel crop? A. near Illinois corn fields B. near Ann Arbor, Michigan C. southern California D. the Pacific Northwest

3 7. Self-shading is A. a problem caused when algae grown in bags or tubes begins to block its own light. B. beneficial in hot dry areas which need protection from the sun. C. the tendency of fuel crops to increase food prices. D. a healthy benefit of algae-based cooking oil. 8. The article says, Because algae needs a source of carbon dioxide to grow, PetroAlgae is seeking to set up joint ventures with electric utilities looking to reduce their carbon emissions. The reader can infer that a joint venture is A. a farming operation that grows two specialized crops. B. a chemical process that removes byproducts. C. a business enterprise in which two or more companies work together. D. a travel plan in which two people or companies journey to a new destination. 9. Which of the following statements best summarizes the main idea of the article? A. Fuel from algae will soon revolutionize the fuel industry world-wide and will cause a dramatic decrease in food prices. B. Algae-based fuels will solve climate problems related to carbon dioxide emissions. C. Development of algae-based fuels is in the experimental stages, but the outlook is promising. D. The United States includes several areas with a climate that is good for growing algae for fuel use. 10. MATH CONNECTION. If an algae grower has 400 tons of algae, how many pounds of water can be removed from the algae? A. 784,000 B. 392 C. 1,960 D. 200

4 Open Response The article discusses several challenges related to algae-based fuel production as well as positive aspects of developing algae-based fuel. Using information from the article, describe two challenges and two positive aspects of developing algae-based fuel.

5 Key Multiple Choice 1. B 2. C 3. D 4. B 5. A 6. C 7. A. 8. C 9. C 10.A Open Response Rubric 4pts.-- Using information from the article, the student describes two challenges and two positive aspects of developing algae-based fuels. (2 and 2) 3pts.-- Using information from the article, the student describes two challenges and one positive aspect of developing algae-based fuels, or visa versa. (2 and 1) 2pts.-- Using information from the article, the student describes two challenges OR two positive aspects of developing algae-based fuels, OR one of each. (2 or 1 and 1) 1pt. Using information from the article, the student describes one challenge OR one positive aspect of developing algae-based fuels. Possible Answers Challenges: 1. The cost of harvesting algae is high. 2. Algae needs a lot of water to grow, so producers must find ways, to recycle water. 3. Because Algae needs a lot of water to grow and sunny places to be dried, finding a suitable location can be a challenge. 4. Self-shading occurs when algae gets slightly dense. Positive Aspects: 1. Algae is a non-food crop, so production should not adversely affect food prices. 2. Algae has a relatively high energy density compared to soybeans, so it can yield more fuel than soybeans per acre. 3. Algae can remove large amounts of carbon dioxide from the air, which can help reduce the carbon emissions of electric utilities.
