  1. The Fossil Fuel Dilemma Global Warming Acid Rain Thermal Pollution Created by: Carrie Rhein Hazelwood Central High School Click Here: Teacher PageTo Activity

  2. In your science journal, list what these pictures have in common! Smoke Stack from a Coal Plant Oil Drill Natural Gas Plant

  3. Please Use Your Science Journal! 1. What is a fossil fuel? 2. List three examples of fossil fuels. 3. Why is it a dillema to continue using fossil fuels?

  4. Here’s the Dilemma: • Fossil Fuels are a nonrenewable resource because they were formed from the remains of plant and animal matter from over 65 million years ago. Once they are gone, they are gone forever! • Some examples of fossil fuels are petroleum, vinyl, Styrofoam, plastics, food additives, paints, fertilizers, synthetic fibers, and thousands of other products. • Many environmental problems our country faces have also arisen from using fossil fuels. Environmental Problems

  5. Some Environmental Problems Caused By Using Fossil FuelsCLICK ON EACH PROBLEM TO LEARN MORE! • Global Warming • Acid Rain • Thermal Pollution ENVIRONMENTAL REVIEW

  6. Global Warming! Gases are emitted when fossil fuels are burned from coal plants and automobiles One of the most significant is carbon dioxide, a gas that traps heat in the earth’s atmosphere. Global average surface temperature has risen 0.5-1.1 degrees Fahrenheit since reliable records began in the late 1800s. This has been attributed to the increase in carbon dioxide. Projected temperature increase could have detrimental effects on the earth. Detrimental Effects on the Earth

  7. Detrimental Effects Caused By Global Warming • In coastal areas, sea level may rise due to the warming of the oceans and the melting of glaciers. • Inland agricultural zones could suffer an increase in the frequency of droughts, resulting in food shortages. • Altered weather patterns may result in more extreme weather events.

  8. What is Acid Rain? • Carbon dioxide gas dissolves into water droplets as they form into rain, producing weak carbonic acid. As a result, normal rain is slightly acidic. • Sulfur released by coal-burning factories and power plants and nitrogen oxide from automobile exhaust pollute the air and combine with the water vapor and increase the acidity of rain. • There are many negative effects of acid rain on the earth Negative Effects of Acid Rain

  9. Effects of Acid Rain • Acid precipitation leaches calcium, potassium, and other valuable nutrients from the soil, making it less fertile. • Acid Rain damages plant tissues. Many trees in the forests of the northern-eastern United States are dying. • Acid Rain falling on lake ecosystems or runoff from streams or neighboring slopes, causes the pH of the lake water to fall below normal, damaging plant and animal life.

  10. What is Thermal Pollution? • During the electricity-generation process, burning fossil fuels produces heat energy. • Much of this heat is released into the atmosphere or to water that is used as a coolant. • Heated air is not a problem. • Heated water, once returned to rivers and lakes, can upset the aquatic ecosystem.

  11. ENVIRONMENTAL REVIEW: • 1. What is Fossil Fuel? • 2. Name three examples of fossil fuels? • 3. Write a sentence behind each one of these environmental problems explaining how each is effecting the earth: • 1. Global Warming- • 2. Acid Rain- • 3. Thermal Pollution- • 4. What can humans do to help relieve the environment from these problems? Back to 1st Slide

  12. Teacher Page • For 9 & 10 grade science students • Objectives: • The learner will be able to research the ways fossil fuels impact ecosystems. (MAP Review) • The learner will be able to define fossil fuels, give examples, and products manufactured from fossil fuels. • The learner will use a science journal to write about three pictures of fossil fuels. • The learner will be able to use a science journal to write down notes on three types of environmental problems created by fossil fuels and their effects on the earth. • HELPFUL HINTS: • The Teacher could use this as an introduction to ecology, showing fossil fuels and the way they impact ecosystems. • The Teacher might want to tell students to answer the question on slide 3 and then go back and change answers after going through the presentation. • The Teacher could guide a discussion of the different pictures without telling: a coal plant, oil drills, and natural gas plant, all which are trying to excavate fossil fuels from the earth. • The Teacher could let the students write in their science journal the answers to slide 3, then let them go back at the end of the discussion and change answers. • The Teacher could ask about each environmental problem and discuss background knowledge. Then go through each slide presentation, having students write down the notes on each one.
