Give two examples of how we can see light energy.

Light energy can come from a light bulb, or from the sun.
100

What is the term for how high or low a sound is?

Pitch

100

What kind of machine converts electrical energy to another form of energy?

electrical device

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

to change from one form to another

convert

When light strikes a surface and it then bounces to another area, this is called _______.
Reflection

Can sound travel through space. Explain with details.

Sounds requires a medium to travel. Gas, water, and solids are necessary. There is no air in space therefore travel cannot travel.

200

What are wires that transfer electrical energy from many sources to many other places?

The electrical grid

200

What is another name for the energy of motion.

kinetic energy

300
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)
300
When light strikes a surface and it causes the light to bend, this is called ________.
Refraction
300

What travels through a soundwave?

Energy

300

How can we generate electricity without using fossil fuels?

We can use solar power, hydroelectric power, or wind power.

vibrates

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.
