What is a microorganism?
A living thing that is too small to see with the naked eye
What is kinetic energy?
The energy of motion
How does the air get its heat?
The sun transfers energy to surrounding surfaces which transfer their heat to the air
What is a greenhouse gas?
A gas that traps heat in our atmosphere
Where does the moon get its light?
From the sun
Are all bacteria harmful to us?
No! Many bacteria are helpful!
What is heat?
A measure of how fast the molecules move in a substance
Which place would experience a warmer temperature? A place near the poles or a place near the equator?
A place near the equator
What causes land and sea ice to melt?
Increasing global temperatures?
How much of the moon is illuminated at once?
Half
What is a molecule?
A molecule is a group of atoms arranged in a particular way
What happens if I put two samples together that are at different temperatures?
They reach equilibrium (their temperatures become the same)
What is water vapor and how does it form?
Water vapor is water in a gas state. It forms by the process of evaporation
Why are the oceans becoming more acidic (lower pH)?
More carbon dioxide is absorbed by the ocean which makes it more acidic
Why do we see different moon phases from Earth?
The moon orbits around the Earth
Why do our bodies perform cellular respiration?
So we have energy to do all the things we need to do!
What is the difference between an insulator and a conductor?
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
Why is ocean acidification a problem?
It prevents shell building animals from making their shells
Name 5 moon phases we might see
New moon, crescent, quarter, gibbous, full
What goes into the mitochondria during cellular respiration and what are the products?
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
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
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)
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
