Math Skill: Place valueRounding

Science Subject: Our Energy Resources

Grade level:  45th grades

Environmental Area: Energy

Area level: National-scale

Purpose: Understand energy use in the top 10 largest per capita energy consuming states including Indiana and develop awareness of energy consumption




Indiana ranked eleventh for per capita energy consumption in the United States in 2017. On average, a person in Indiana consumes more than twice as much energy as a person in New York. In Indiana, about 50% of electricity comes from burning coal (U.S. EIA), therefore, the high energy consumption resulted in a large amount of carbon dioxide emissions, air pollution, and climate change.
