Planning and Creating a Presentation In this activity, you’ll prepare a 10- to 15-slide presentation using presentation software. You’ll examine the chemical reaction that takes place when burning fossil fuels and how this process affects the environment. You’ll also evaluate and compare fossil fuels with biomass and other renewable energy sources. Then you’ll make a recommendation about which energy sources to develop in your local area. Be sure to support your recommendation with information provided by credible sources.

Follow the links provided throughout the activity. They will help you plan and research your presentation. This guide about the research process provides a helpful overview of the steps you should take.
