A electrical solar light and mechanical B sound mechanical light and electrical C mechanical solar sound and heat D solar electrical sound and mechanical SAISD 06 Science FMA December 09 Page

2 For a science project, a student was conducting research on the energy transformations of different types of power plants. After completing his research comparing hydroelectric power plants to wind power plants, the student concluded that F hydroelectric power plants convert solar energy to water energy G wind power plants convert wind energy to sound energy H hydroelectric and wind power plants are mainly used to grow crops J hydroelectric and wind power plants are mainly used to produce electricity What is one of the major problems with using wind power as an energy source? A It creates more toxic waste than other power plants. B The equipment to collect wind energy does not exist. C Wind cannot produce a constant supply of electricity. D There is never enough wind to make wind power plants work. Which of the following is a conversion from chemical energy to thermal energy? F Browning toast in an electric toaster G Burning charcoal in a barbecue pit H Drying hair with a hair dryer J Ironing clothes with an iron When you turn on a light bulb in your house, you convert A potential energy into electrical energy and light energy B electrical energy into kinetic energy and light energy C electrical energy into light energy and thermal energy D chemical energy into light energy and thermal energy 6 Our world contains many sources of energy. We can capture energy from the sun and the wind. We can also produce energy by burning fossil fuels containing stored energy. All of the following are true statements concerning energy resources except F solar energy and wind power are renewable resources G coal and natural gases are nonrenewable resources H nonrenewable resources, such as fossil fuels, only take a few years to create J renewable energy sources are better for the environment than using nonrenewable resources SAISD 06 Science FMA December 09 Page

3 7 A science teacher is conducting a demonstration in her classroom. This demonstration requires the use of a hot plate to heat a beaker of water. What transformation of energy occurs in order for the temperature of the water to increase? A Solar energy to heat energy B Electrical energy to light energy C Heat energy to light energy D Electric energy to heat energy 8 A piece of pizza is placed in a toaster oven to warm up. The energy conversion that takes place in a toaster oven is F light energy to electrical energy G chemical energy to thermal energy H thermal energy to electrical energy 0 During science class, a student was comparing a solar powered calculator to a battery powered calculator. The student concluded that Type of Energy Source F both calculators convert light and heat energy into electrical energy G the calculators convert different forms of energy into electrical energy H solar powered calculators convert electrical energy to solar energy J battery powered calculators convert nuclear energy into electrical energy Electricity Production by Energy Source Hydroele ctric Natural Gas Petroleum Nuclear age Coal According to the data displayed on the graph above and the pattern observed from this information, what would happen if coal were no longer available to produce electricity? J electrical energy to thermal energy A The primary source of electricity would no longer be available. 9 To heat water using a renewable energy source, you would use A oil B solar energy C natural gas D coal B The lack of coal would not affect the production of electricity. C The use of petroleum for producing electricity would decrease. D Nuclear power would no longer be used to generate electricity. SAISD 06 Science FMA December 09 Page

4 Use the pie graph and your knowledge of energy types to answer questions and. The pie graph below compares the amounts of energy from different sources used in the United States each year. Hydropower % Nuclear % Other % (wind, solar, geothermal) Oil % Coal % Natural gas % Which of the following energy sources when combined together provide more than 0% of the energy needs in the United States? F Nuclear and natural gas G Hydropower and oil H Oil and coal J Natural gas and coal Most of the resources used to produce energy are from fossil fuels. Why is it important that society stop relying so heavily on fossil fuels? A Oil, coal, and natural gas are non-renewable resources. B Fossil fuels are more expensive to process and use. C Fossil fuels can only be used to generate electricity. D Oil, coal, and natural gas provide only a small amount of energy. SAISD 06 Science FMA December 09 Page

Which graph correctly displays the energy consumption data found in the chart above? F H G J SAISD 06 Science FMA December 09 Page

6 Energy Resource Fossil Fuels Nuclear Solar Water Advantages Fossil fuels provide a large amount of thermal energy per unit of mass. Fossil fuels are easy to transport. Fossil fuels can be used to generate electrical energy and to make products, such as plastics. Nuclear resources are very concentrated forms of energy. Nuclear power plants do not produce smog. Solar energy provides an almost limitless source of energy. Solar energy does not produce pollution. Water is renewable. Water does not produce smog. Disadvantage Fossil fuels are nonrenewable. Fossil fuels produce smog when burned. Burning coal releases substances that can cause acid precipitation. Fossil fuels cause damage if spilled in transport. Nuclear resources produce radioactive waste. Radioactive elements are nonrenewable. Solar energy is expensive to use for large-scale energy production. Solar energy is practical only in sunny areas. Dams disrupt a river's ecosystem. Water as an energy resource is available only in areas that have rivers. According to the information in the chart, which of the following would be the best energy resource to use because it is a limitless resource and does not harm the environment? A Fossil fuels B Nuclear C Solar D Water SAISD 06 Science FMA December 09 Page 6
