Apply what you know
100
The type of energy that transformation that happens when you turn on a radio.
What is electrical to sound energy?
100
The only waves that we are able to see is called _____ light.
visible light. Other animals are able to see others waves such as ultraviolet and infrared.
100
How do we measure the volume of sound? Hint: we use inches in class.
To measure the volume of a sound we use decibels.
100
What kind of circuit allows electricity to pass through. Closed or open?
Closed circuit.
100
Is this true: can energy transform, or change, from one form into another.
Yes, energy can change from one form to another. For example, light energy can be captured by solar panels and transformed into electric energy to power a home, car, and many other things.
200
What is a conductor.
Conductors allows electricity to easily travel through them. Some good conductors include metals. Conducts comes from the word conductus which means a carrier.
200
When light strikes a surface and it then bounces to another area, this is called _______.
Reflection
200
Can sound travel through space. Explain with many details.
Sounds requires a medium to travel. Gas, water, and solids are necessary. There is no air in space therefore travel cannot travel.
200
Why do the lights turn off in class when we hit the switch?
The closed circuit is then turned into an open circuit.
200
The energy of motion.
kinetic energy
300
When the string of a guitar vibrates, it produces _______.
sound energy
300
When light strikes a surface and it causes the light to bend, this is called ________.
Refraction
300
A student uses a set of headphones to listen to music. Which item uses the same source of energy as the headphones? A flute, keyboard, or teapot.
The keyboard requires electrical energy just like the headphones. Even wireless headphones require to be charged , this is still electrical energy.
300
Explain how electric energy can be produced without the usage of fossil fuels.
We can use solar panels, riverbanks, and turbines to help us produce electric energy without using fossil fuels.
300
Why does a fisherman have a hard time catching fish just by simply looking at the fish. Explain with many details.
Refraction is causing the fish to appear to be in one place, but it is in another place.
400
The water in a swimming pool tends to be warmer in the daytime and cooler at night. What natural source of energy causes the difference?
Solar energy from the sun. (thermal energy)
400
What are three ways that we can describe how light is absorbed by a medium? Transparent, ________, and ________. You must also explain each term.
transparent - light passes through translucent - some light is able to pass through opaque - little to no light is able to pass
400
This causes sound to have a higher pitch.
Sounds waves are closer together.
400
What does the work repel mean?
When two items have the same charge they are pushed away from each other.
400
This is where a roller coaster car has the most potential energy.
at the top of the biggest hill
500
What are three forms of energy that we can observe when fireworks explode?
Thermal (heat) energy light energy sound energy
500
Why are we able to see rainbows after a storm?
The water molecules in the air behave like prisms and break up white light so that we can see all the colors that make up visible light.
500
The measure of loudness.
decibels
500
Microwave heating food.
What is an example of radiation
500
This is what happens with potential energy and kinetic energy when a ball rolls down a hill.
