What is kinetic energy?
What is the biggest source of heat energy for the Earth, which warms land, water, and air?
What is the sun?
Amplified means
What is louder?
It is how loud or soft sound is
What is volume?
Explain transparent, transluscent, and opaque
Transparent - Allows light to pass through

3 ways in which heat energy moves in different ways?
What are conduction, convection, and radiation?
The area after the eardrum.

Explain sound using the words energy, vibration, and waves.
Sound is energy caused by vibration that creates waves.
What is bioluminisence?

Give an example of a nature that uses movement energy
Which heat energy travels through space as rays or waves?
What is radiation?
Explain what happens to the pupil when there is too much or less light.
It becomes larger when there is less light and smaller when there is too much light.
Explain what is lower amplitude and higher amplitude.
Low amplitude - Low sounds / Low volume
High amplitude - High sounds / high volume
Explain how do we see.
Light appears to travel in straight lines until it reaches an object. Then, light is reflected by the object, and it enters our eyes.
Give two examples of movement energy that we use every day.
Answers may vary.
Explain how Conduction and Convection different.
Conduction - Heat travels through solid object
Convection - heat travels through liquids and gases.
Explain echolocation
Some animals use their super hearing to their advantage, utilizing the echo for their benefit. Sound bounces off different objects.
