200
Two positively charged objects will attract (push away) from each other, while a positive and negative charge will repel each other. True or False
What is, False. Two positively charged objects will repel (push away) from each other, while a positive and negative charge will attract each other.
200
Go to the white board a draw me a picture of a series circuit indicate how the electrons flow.
Discuss drawing with class
300
Parts of a series circuit are connected to a single loop.
What is True
300
A branch of science that studies the use of electric current and the development of electronic devices.
What is, What is the science of electronics?
300
Conductors allow electric current to move through them easily, insulators do not.
What is, How are conductors different from insulators?
300
Parts of a parallel circuit are connected with a single loop. True or False
What is, False. Parts of a parallel circuit are connected with many paths.
300
Fossil fuels, and Nuclear energy.
What is, Nonrenewable energy sources?
400
Electrical energy will flow through a open circuit but not through an closed circuit.
What is False, Electrical energy will flow through a closed circuit but not through an open circuit.
400
It converts mechanical energy into electrical energy using magnets and a coiled wire.
What is, What does a generator do?
400
Electrons are moving in electric current but are not moving in static electricity.
What is, What is the difference between static electricity and electric current?
400
Solar, Wind, Hydroelectric, Biomass, and Geothermal.
What is, Renewable energy sources?
400
Go to the white board a draw me a picture of a parallel circuit indicate how the electrons flow.
Discus drawing with the class.
500
Electric wires make good conductors, because the atoms are tightly attached to one another allowing electrons to flow easily through them.
What is False,Electric wires make good conductors, because the atoms are loosely attached to one another allowing electrons to flow easily through them.
500
It converts the energy from steam of fluid into mechanical energy.
What is, What does a turbine do?
500
Realized, an electric current can act like a magnet.
What is, What did Hans Christian Oersted discover?
500
In your own, explain how wind power is used to create electricity.
The blades of a windmill act as turbines, which power a generator. A powerful magnet and moving parts inside the generator produce an electric current in a coil of wire. Energy-Fluid,Steam,Wind-Mechanical-Electricity

Use your own words, explain how the development of the microchip changed our lifestyle.
Before the microchip was invented, the use of vacuum tubes made computers large, heavy, expensive and less efficient. Microchips greatly reduced the size and cost of computers, allowing the development of personal computers. Microchips also greatly increased the ability of computers.
