Forms of Energy
This form of energy comes from the Sun and lets us see.
What is light energy?
When you turn on a lamp, electrical energy changes into this.
What is light energy (and heat)?
This type of energy source can be used again and again without running out, like the sun or wind.
What is a renewable energy source?
Turning off a light when you leave a room is an example of this.
What is conserving (saving) energy?
Burning fossil fuels releases gases that contribute to this global problem.
What is climate change?
This form of energy is produced by vibrations and travels to your ears.
What is sound energy?
When a ball rolls down a hill, its potential energy changes into this
What is kinetic energy?
This type of energy source will eventually run out because it takes millions of years to form.
What is a non-renewable energy source?
This is one simple way to save energy at home involving your thermostat
What is turning down the heat / adjusting the temperature?
True or False: Once non-renewable energy sources run out, humans can make more of them quickly.
What is False
This is energy of motion.
What is kinetic energy?
A stretched slingshot is pulled back and held still. What kind of energy is stored in the stretched band before it's released?
What is elastic (potential) energy?
These machines use wind to generate electricity.
What are wind turbines (windmills)?
Walking or biking instead of driving a car saves this type of non-renewable resource
What is gasoline (fossil fuel)?
This is the name of the force that makes a dropped object fall and gain kinetic energy
What is gravity?
This is stored energy, like a stretched elastic band or a ball at the top of a hill.
What is potential energy?
This word describes energy moving from one object to another, like heat moving from a hot pan to your hand.
What is energy transfer?
These panels capture energy from the sun and turn it into electricity.
What are solar panels?
This household item, when left plugged in and on, uses standby energy even when you're not using it.
What is a TV, computer, or charger? (any device accepted)
This renewable energy source uses moving water, often from a dam, to generate electricity
What is hydroelectric power (water power)?
This form of energy makes things feel warm, like a stove or a campfire.
What is heat (thermal) energy?
This is what happens when energy changes from one form into a different form, like food energy becoming movement energy in your body.
What is energy transformation?
Coal, oil, and natural gas are all examples of this type of non-renewable energy source
What are fossil fuels?
This type of light bulb uses much less electricity than an old-fashioned incandescent bulb to produce the same amount of light
What is an LED bulb?
This is a simple definition of energy: the ability to do ___.
What is work?
