What is a microorganism?

A living thing that is too small to see with the naked eye

100

What is kinetic energy?

The energy of motion

100

How does the air get its heat?

The sun transfers energy to surrounding surfaces which transfer their heat to the air

100

What is a greenhouse gas?

A gas that traps heat in our atmosphere

100

Where does the moon get its light?

From the sun

200

Are all bacteria harmful to us?

No! Many bacteria are helpful!

200

What is heat?

A measure of how fast the molecules move in a substance

200

Which place would experience a warmer temperature? A place near the poles or a place near the equator?

A place near the equator

200

What causes land and sea ice to melt?

Increasing global temperatures?

200

How much of the moon is illuminated at once?

Half

300

What is a molecule?

A molecule is a group of atoms arranged in a particular way

300

What happens if I put two samples together that are at different temperatures?

They reach equilibrium (their temperatures become the same)

300

What is water vapor and how does it form?

Water vapor is water in a gas state. It forms by the process of evaporation

300

Why are the oceans becoming more acidic (lower pH)?

More carbon dioxide is absorbed by the ocean which makes it more acidic

300

Why do we see different moon phases from Earth?

The moon orbits around the Earth

400

Why do our bodies perform cellular respiration?

So we have energy to do all the things we need to do!

400

What is the difference between an insulator and a conductor? 

An insulator keeps the temperature the same, a conductor loses or gains heat quickly
400

Think about rainstorms - an air parcel that rises higher will create a bigger storm. Why?

The higher an air parcel goes into the atmosphere, the more energy it releases and the bigger the storm is

400

Why is ocean acidification a problem?

It prevents shell building animals from making their shells

400

Name 5 moon phases we might see

New moon, crescent, quarter, gibbous, full

500

What goes into the mitochondria during cellular respiration and what are the products?

Oxygen and glucose go in, carbon dioxide, water and energy come out
500

I put some ice into a glass of lemonade on a hot day. The lemonade cooled down. Why did this happen?

The heat from the lemonade transferred into the ice

500

Why do some places that are not near the equator experience a warmer than expected temperature?

Because ocean currents bring warm water from the equator to those places. The water transfers energy to the air

500

What is an example of a trend vs a fluctuation with global temperature?

The trend is that global temperature is increasing, but year to year the temperature fluctuates (some years it goes down, others it goes up)

500

What causes a lunar eclipse?

The sun is in between the sun and the moon, casting a shadow on the moon so it is no longer illuminated
