Vocabulary
An electric charge in motion that flows quickly and invisibly from one place to another.
Electric current
These transform energy to other forms of energy. They use the energy that flows through the circuit. An example is a light bulb.
Resistors
When you perform an experiment, you should form a _________. This is your guess as to what will happen in the experiment based on what you know.
Hypothesis
A ____________ uses resistors to transform electricity into heat.
Toaster
Car engine
Gas stove
Wind turbine
Toaster
This part of a flashlight is a resistor, converting electricity into light energy.
Light bulb
A material through which an electric charge moves with difficulty. These make electrically charged objects safe to handle. Example: the handle on a chord, rubber, glass, plastic
insulator
A thin-coiled resistor that transforms electrical energy into heat and light energy is called..
filament
The things that can vary or be changed in an experiment are called the _____________.
Variables
A good energy source for a simple circuit is a
Battery
Copper wire
Light bulb
Switch
Battery
This part is an insulator, allowing the flashlight to be handled without electric shock.
The handle
In this type of circuit, electric charge can flow in only one circular path. Any break in the loop stops the current for flowing.
Series circuit
A force that acts when two surfaces rub together. It is caused by the energy of motion.
Friction
One way to document your data is by creating a _____________
chart, graph, data table
Which of the following would be the best insulator for a metal wire?
Silver
Graphite
Glass
Copper
Glass
This part is a conductor, carrying charges from the battery to the light bulb.
Wire
This type of circuit has two or more paths through which electric charges may flow. Each path leaves the power sources and returns to it. The current that flows through one path does not have to flow through the other paths. If one loop in the circuit is broken, the current will still flow through the other loops.
Parallel circuit
A material through which electric charges can move easily. Example: metal, gold
Conductor
The variable you do not change in an experiment is called the ____________________.
Control
What will happen in a parallel circuit if one of its loops is broken?
Electric current will still flow through the unbroken loop (remember parallel circuits have more than one loop/path for the current to flow
This part is a switch, opening and closing the circuit.
On/off button
Batteries and electrical outlets are..
energy sources
Rochelle has an electrical company that provides electricity to Rochelle residents. Your parents pay a monthly bill to this company. What is the name or abbreviation of this company?
RMU
Experiments begin with a _______________. This takes place before the hypothesis.
Curiosity or question
List three appliances that transform electrical energy into another form of energy.
Toaster, porch lights, washing machine, etc.
This part is the energy source, providing the energy for the flashlight to generate light.
