This is the shape of our Milky Way Galaxy.

What is a spiral (or barred spiral)?

The universal solvent.

What is water?

This movement in air and water currents is caused by the uneven heating of the Earth by our sun.  (Hint:  Remember that hot air/water rises and cool sinks.  It also happens below Earth's surface, but that's not the sun's fault.)

What is a convection current?

These are known as the building blocks of life
What are cells?

This network carrying surface water is fresh water, is fed by smaller tributaries, and typically empties out into a lake or the ocean.

What is a river?

This is what we call speed AND direction.

What is velocity?

This organelle is known as the cell's "powerhouse", breaking down sugars and providing energy to the cell.
What is the mitochondria?
300

This nickname for Earth's location explains the "just right" position we're in for life on our planet.

What is the Goldilocks Zone?

300

We can calculate this property of a substance by dividing its mass by its volume.

What is density?

This global warming phenomenon is named after a glass building used to provide light and heat to grow plants. It is responsible for changes in our climate.

What is the Greenhouse Effect?

300

This weather system shows an increase in atmospheric pressure that begins with light rain followed by nice, clear weather.

What is a High pressure area?

While cells are known as the "building blocks of life", this material is known as the "blueprint of life". It is shaped like a double helix, found inside the nucleus, and it allows important characteristics to replicate and be passed on to the next generation.
What is DNA?

When looking at the electromagnetic spectrum, it is the spectra with the shortest and highest energy and frequency wave that can cause cellular damage in humans with exposure.

What is gamma radiation? (or gamma rays)
