Energy
The energy of position
Potential Energy
Circuit with 1 path for the energy to flow
Series Circuit
As you add more light bulbs in a series circuit what happens to their brightness?
Bulbs get dimmer
Name one factor that affects the resistance of a wire.
Type of metal, length, or diameter
Scientific Name for the water cycle
Hydrologic Cycle
The energy of movement
Kinetic Energy
A circuit with multiple paths
Parallel Circuit
This describes how fast the electrical charges are moving in a circuit. How fast is the flow of electricity?
Current
In which circuit (series or parallel) do devices share the same current?
Series
The process/steps scientists use to study the world around them
Scientific Method
The sum of an objects potential & kinetic energy
Mechanical Energy
What type of material does not allow energy to flow through it?
Insulator
What does LED stand for
Light Emitting Diode
Provide one real-world example of a device or system that uses parallel circuits and explain why parallel wiring is used there.
Household Wiring (one example)
Name all of the Great Lakes
Erie, Michigan, Huron, Superior, Ontario
Law that states energy is not created or destroyed (it simply changes forms)
Law of conservation of energy
Voltage changes in this circuit. (12V battery 3 lights they each get 4V)
Series Circuit
An LED allows electricity to flow through it. What type of material allows electrical energy to flow?
Conductor
Give two forms of energy that an electrical device might produce
Light, sound, thermal, mechanical (any two).
A special type of evaporation where water escapes through the leaves of plants/trees
Transpiration
What two variables affect the amount of kinetic energy an object has?
Mass and Velocity (speed)
What is the unit of measurement for electrical current?
Amp or Ampere
How many volts are standard AA or AAA batteries? (throw away when done batteries)
1.5 volts
Explain how the energy transferred from a battery eventually becomes light in a bulb (include charge movement and energy transformation).
The source raises the potential energy of charges; as charges pass through the filament, electrical energy is transformed to thermal energy (heating the filament) and then to light.
Name all the layers of the atmosphere
Troposphere Stratosphere Mesosphere Thermosphere Exosphere
