NONRENEWABLE RESOURCES
A nonrenewable resource is a natural resource that cannot
be re-made or re-grown
● Coal ● Natural Gas ● Nuclear● Oil

Solar panels on the roof of a house are most beneficial to a home owner because they
Can Heat water for the house.
Why? Solar energy can be converted to electrical energy and water heaters run on electricity.

Which of the following would be classified as a renewable energy source?
Hydropower, because water is everywhere and is easily available.

Which of the following energy sources is considered non-renewable?
Propane, because once it runs out it is gone.

Conductivity
• Conductors:– can carry electrical current easily.– Examples: metals (pennies and
paperclips)
• Semiconductors– Are in between conductors and
insulators.
• Insulators:–Do not carry electrical charge.– Examples: Glass and plastic

•Has only one path for electricity to flow
•If any part of the circuit is broken, then the all lights will go off.•Ex’s: Christmas tree lights
•In a series circuit, the light bulbs are DEPENDENT of each other.•It is like adding pinches to a hose.

•Has multiple paths for electricity to flow•If any part of the circuit is broken, the remaining lights will stay on. •Ex’s: your home!!
•In parallel circuits, the light bulbs are INDEPENDENT of each other.•They have no effect on each other.
