What instrument measures air pressure?
A push or pull
What is a supernova?
An extremely bright, super powerful explosion of a star.
Explain the difference between renewable and nonrenewable energy.
Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes, while renewable energy comes from natural sources or processes that are constantly replenished.
Who came up with the idea of natural selection?
Charles Darwin
Air always travels from areas of ____ pressure to ____ pressure.
high; low
Lever, Wheel and axle, Pulley, Inclined Plane, Wedge, Screws
What is the name of the stage that stars spend a majority of their life cycle in?
Main sequence
Name one advantage and disadvantage of using fossil fuels for energy.
Advantages: inexpensive, can be stored and shipped anywhere in the world, reliable
Disadvantages: pollution, imbalance of carbon budget, global warming, dangerous to extract
Explain survival of the fittest and natural selection.
In evolutionary theory the survival of only those organisms best able (fittest) to obtain and utilize resources. These organisms than reproduce, thus passing down their genes.
What two elements make up a majority of the Earth's atmosphere?
Nitrogen (78%) and Oxygen (21%)
Name three real-world examples of levers.
Seesaw, wheelbarrow, tweezers, etc.
What type of galaxy is our Milky Way galaxy?
Barred spiral galaxy
What are the best places to harness wind energy?
The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains - places where the wind is strong and reliable.

Why do dogs bark?
So that humans can understand their needs. Their owners can distinguish between an alarm bark and a play bark.
Describe an optical phenomena that we talked about (other than a rainbow) and what it looks like.
Multiple correct answers.
Describe the changes in kinetic and potential energy as a roller coaster is travelling up and down the hill.
Potential energy highest and the top. Converts into kinetic energy as roller coaster travels down the hill. Highest kinetic energy at the bottom. Kinetic energy converts back into potential energy as the roller coaster goes back up.
A phenomenon where electromagnetic radiation (such as light) from an object undergoes an increase in wavelength.
A phenomenon where the radiation we observe has decreased its energy. Red light is less energetic than blue, hence the term redshift.
Name a sustainable invention that we talked about and briefly describe it.
Multiple correct answers.
What is the name of the muscle in the foot that is so underdeveloped in humans that 9% of them are now born without it. This muscle was used by animals to grip and manipulate objects with their feet.
