Scientists are looking for alternatives to fossil fuels. Fossil fuels are nonrenewable, and they pollute the environment. Biofuel is an alternative type of fuel. Biofuels are made from recently living organisms, so they are a renewable energy source.
Write a report about the use of biofuels as an alternative energy source. Before you begin, you will need to research biofuels and fossil fuels. Here are some questions to guide your research:
What problems arise from using fossil fuels?
What are biofuels, and how are they made?
What are the advantages and disadvantages of using biofuels?
Are you ready? Begin by visiting the Web sites in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.
With teacher supervision, you may use search engines to research other Web sites. You also can research biofuels and fossil fuels at the library. When you are ready, follow Steps 3 and 4 to write your report.
Step 2. Research
Research answers to the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
