Renewable
This renewable resource provides light and heat to Earth every day.
This black rock is burned to produce electricity.
Coal
This form of energy powers lights, TVs, and computers.
Electrical Energy
This is the name for a path that allows electricity to flow from one place and back again.
a circuit
What is the largest organ in the human body?
Skin
This renewable resource uses moving air to generate electricity.
The Wind
This non-renewable resource is pumped from the ground and used to make gasoline.
Oil
Why are metals like copper and aluminum commonly used in electrical wires?
They are conductors
What are the two ends of a battery called?
Positive and negative
What is the only mammal capable of true flight?
A bat
This renewable resource can be used to generate electricity when it flows through dams.
Water powered
Coal, oil, and natural gas all belong to this group of energy resources.
Fossil Fuels
A flashlight has a working battery and bulb, but the bulb won't light because there is a gap in the wire. What needs to happen to fix it?
What are the three basic things needed to make a simple circuit work?
A power source (battery), wires, and a device (light bulb).
What is the hardest natural substance on Earth?
Diamond
Explain why soil is considered renewable, but it can take a very long time to replace.
Nature can create more.
Why are non-renewable resources considered non-renewable?
They can't be replaced in our lifetime
How does a solar panel use energy from the Sun to create electricity?
Solar panels capture sunlight and convert it into electrical energy.
What would happen if you replaced a copper wire in a circuit with a rubber band?
The rubber band would act as an insulator, so the circuit would not work.
What travels faster: sound or light?
light
A town uses sunlight, wind, and flowing water to make electricity. What do all three resources have in common?
They are renewable resources that nature can replace.
Imagine humans use all the oil stored underground. Why can't we simply make more oil next year?
Oil takes millions of years to form from the remains of ancient organisms.
a form of energy caused by the movement or buildup of tiny particles called electrons.
Electricity
Why does a light bulb turn off when you open a switch?
The switch breaks the complete path.
Why don't birds get electrocuted when they sit on power lines?
Electricity needs a complete path to flow. Both of the bird's feet are touching the same wire, so there isn't enough of a voltage difference to push dangerous electricity through its body.
