A material that resists the flow of electrons is called a(n)
conductor
resistor
circuit
insulator
Select the sentence that best describes why plastics and rubbers are good insulators.
In order for a material to be a good insulator, the electrons must be able to move freely into and out of the atom.
Many materials like plastics and rubber do not have any loosely bound electrons in their outer shell making it difficult, if not impossible, for electrons to move between atoms.
Plastics and rubber atoms have the same number of neutrons and electrons. This allows them to share electrons with other materials, allowing electric current to flow freely.
The free& dash flowing arrangement of the plastic and rubber atoms make them able to freely accept electrons and allow the flow of electricity.
Which statement best explains the relationship between current, voltage, and resistance?
If we increase the amount of voltage applied, and do not change the resistance, this will result in a decrease in current.
If we decrease the current applied, and do not change the resistance, we increase the voltage.
If we increase the amount of voltage applied, and do not change the resistance, we will also increase the current.
If we decrease the amount of current, this will not affect the amount of voltage, only the amount of resistance.
If you were going to describe the relationship between current, voltage, and power, you could say
"If there is a decrease in power, there must have been an increase in either current or voltage."
"If you decrease your voltage, and all other factors remain the same, you will have an increase in power."
"In order to gain more power you would need to increase either current or voltage."
"The only way to increase your power is to change your voltage and keep your current the same.

Which example describes a non–renewable resource?
In some areas in California, people can use heat found deep in the Earth to heat their homes.
Refineries process oil, found in the Earth, and turn it into gasoline to be used by cars
The town has decided to install solar panels on all city buildings.
The hilltop lodge has a windmill that generates enough electricity to power the entire house.
Select the example that best describes a renewable resource.
After a shuttle launch, you can smell the jet fuel for hours.
Solar panels generate electricity that keeps the satellites running.
We use our barbeque every night; it cooks with propane.
Tractor trailers are large trucks that run on diesel fuel.
In some areas, farmers have installed windmills to generate electricity to run the farm. Some are generating a surplus of electricity and selling it back to the power company. The local power company burns fossil fuels, which pollute the environment, to generate electricity. Windmills do not pollute the environment. Evaluate the statements and choose the statement that best describes how the windmill technology benefits the environment.
Windmill technology is a valuable resource that should be used whenever possible. The great advantage is that it uses a non–renewable resource, the wind, to generate electricity. This is an advantage because non–renewable resources will always be available.
Windmill technology allows individuals to generate power without polluting the environment. Some individuals could make money selling the power to the power company. This extra money will make the farmers' lives better.
Windmill technology can generate power using a renewable source of energy that does not pollute the environment. By generating a surplus of energy, individuals can sell it to the power company which can replace the energy generated by burning fossil fuels.
Windmill technology might use a renewable resource to generate power but putting the windmills up along the farms damages the environment. The advantage of using a renewable resource to generate power is less important than keeping farms free of windmills that might take up space.
Satellite technology has allowed us to monitor areas that were once so remote that we had no way of monitoring them. Review the statements and choose the one that best describes how we can use this technology to benefit the environment.
North American forests and their ecosystems are some of the most important and difficult to monitor. Satellite surveillance allows us to detect fires in these remote areas and direct firefighting activities early so fires can be quickly contained.
Satellite surveillance has been a great help in the war against smugglers. Law enforcement officials are able to use satellites to track and predict the activities of smugglers. We are all safer because of satellite surveillance.
Satellite surveillance helps us identify the different types of vegetation that cover remote areas. We can then record and catalogue the different types of grasses, bushes, and trees.
Satellites can help us monitor weather conditions all over the world. This can help travelers plan for the weather when they are traveling to other states or countries.
