Gas+Panic

**Science 10 Problem Based Learning Curriculum Resource: Gas Panic**
In this case, students are working for Cherry Oil and Petroleum Corp. As they are filling up at a gas station, the addition of 10% ethanol into gasoline is questioned. Students research further to develop an awareness campaign in order to explain the need to replace society’s dependency on fossil fuel with renewable energy resources such as ethanol. Students completely describe the combustion reaction of the hydrocarbon ethanol and must be able to explain the balanced chemical equation complete with all the molecular names as well as the potential benefits of using this renewable fuel source. Students go on to explore the combustion reactions of numerous hydrocarbons, covalent bonding and naming molecular compounds. Endo and Exo-thermic reactions are discussed as well as incomplete combustion.
 * Case Focus: **

// How can we develop an awareness campaign that explains the need to replace fossil fuel dependency with renewable energy sources (ethanol) in such a way that will describe the combustion reaction of ethanol, provide a balanced chemical reaction, and articulate the benefits of ethanol use? //
 * Sample Problem Statement: **

Physical Science: Chemical Reactions (CR) CR1 Observe common chemical reactions in your world CR2 Represent chemical reactions symbolically using models, word equations, and balanced chemical equations CR3 Identify characteristics of chemical reactions involving organic compounds
 * Objectives Met: **
