Science Class Connect Rules • Respect the classroom and our privileges • Do not pollute the chat box • Stay on topic • Science class connects are not free chat sessions • Respect the teacher and your peers • Be appropriate and use good language • Be kind to others • Class connects are a time to learn • Have fun! • Science is cool and full of lots of fun lessons and labs! If you are unable to follow these three rules your privileges will be taken away!
Which is classified as a renewable resource? $100 Coal Wind Oil Uranium
The class says: $100 The answer is: B. Wind
Which fuel is used for nuclear power? $200 Coal Oil Natural gas Uranium
The class says: $200 The answer is: D. Uranium
Which is related to air pollution in Mexico City? $400 Burning fossil fuels Using hydropower Using biofuels Collecting natural gas
The class says: $400 The answer is: A. Burning fossil fuels
Which is a cost that comes with using coal as an energy source? $300 Coal produces less energy than most other energy resources. Coal will stay plentiful in the United States Mining coal improves the environment. When burned, coal produces pollutants that are released into the air.
The class says: $300 The answer is: D. When burned, coal produces pollutants that are released into the air.
What is the name of the renewable fuel used in Brazil that helps to conserve petroleum resources? $100 Liquid paper Ethanol Soybeans Aluminum
The class says: $100 The answer is: B. Ethanol
Which tool converts sunlight into electricity? $200 Copper tubing Turbine Battery Photovoltaic cell
The class says: $200 The answer is: D. Photovoltaic cell
$100 How does wind power generate electricity? Air currents spin a propeller that drives a turbine-electric generator. Hot air converts water to steam and drives a turbine-electric generator. Air currents collide with a special cell that releases electrons which forms electricity. Hot air moves electrons in a special wire, which creates electricity.
The class says: $100 The answer is: Air currents spin a propeller that drives a turbine-electric generator.
$400 What is the purpose of the three R’s of resource management? To spread out landfill areas To conserve resources To consume increasing amounts of natural resources To remove resources from homes
The class says: $400 The answer is: B. To conserve resources
Which statement comparing examples of renewable and non-renewable resources is true? $200 Geothermal energy is a non-renewable resource because it can’t be used up, but natural gas is a renewable resource because it will eventually run out. Geothermal energy is a renewable resource because it can’t be used up, but natural gas is a non-renewable resource because it will eventually run out. Both geothermal energy and natural gas are renewable resources because they will never run out. Both geothermal energy and natural gas are non-renewable resources because they will eventually run out.
The class says: $200 The answer is: B. Geothermal energy is a renewable resource because it can’t be used up, but natural gas is a non-renewable resource because it will eventually run out.
Why is oil referred to as a fossil fuel? $400 Oil was formed from decaying layers of plants in swamps millions of years ago. They fossilized into oil. Oil formed from dead marine organisms that fell to the ocean floor, were covered by ocean sediments, and broken down by bacteria into oil over millions of years. Oil was formed from the breakdown of igneous rocks over millions of years. Oil was formed from black shales that were uplifted millions of years ago and fossilized into oil.
The class says: $400 The answer is: B. Oil formed from dead marine organisms that fell to the ocean floor, were covered by ocean sediments, and broken down by bacteria into oil over millions of years.
Which correctly compares how coal and oil are formed? $200 Coal results from the compressed remains of plant materials while oil is the compressed remains of marine organisms. Coal was made due to the pressure under buried layers of rock over millions of years, while oil was made by heating the compressed remains from magma underneath. Coal results from the compressed remains of marine organisms, while oil is the compressed remains of plant. Both are made due to pressure and heat under buried layers of rock over millions of years. Coal results from the compressed remains of plant matter, while oil is the compressed remains of marine organisms. Both are made due to pressure and heat under buried layers of rocks over millions of years. Coal resulted from the compressed remains of plant matter, while oil is the compressed remains of marine organisms. Oil was made due to pressure and heat under buried layers of rock over millions of years, while coal was made by heating the compressed remains from magma underneath.
The class says: $200 The answer is: C. Coal results from the compressed remains of plant matter, while oil is the compressed remains of marine organisms. Both are made due to pressure and heat under buried layers of rocks over millions of years.
$100 Which describes how a turbine works to produce energy for electricity? The spinning turbine creates wind that drives the generator to make electricity. The spinning turbine collects heat from decaying radioisotopes and the heat energy drives the generator to make electricity. Energy from various sources (hydroelectric or burning fossil fuels) is used to spin the blades of the turbine. The turbine then powers a generator, which produces electricity. The turbine collects wind energy to make electricity directly.
The class says: $200 The answer is: C. Energy from various sources (hydroelectric or burning fossil fuels) is used to spin the blades of the turbine. The turbine then powers a generator, which produces electricity.
$400 Which is NOT a way that people can conserve natural resources? Use more packaging in products Walk instead of drive Recycle glass products Turn off unused lights
The class says: $400 The answer is: A. Use more packaging in products
