Mountains can cause one side of the mountain to get lots of rain, and the other side to be very dry - a rain shadow!

- Wind carries water vapor from the ocean towards the mountain.
- As the air reaches the mountain, it is forced up. Higher in the sky, the temperature is much colder. This cold causes water vapor in the air to condense, form into clouds, and fall as rain.
- By the time the air passes over the mountain, most of the water in the air has already fallen as rain - the other side of the mountain is a rain shadow (area with very little rain, because of the mountain).

Multiple Choice

Which city will get the most rain? Why?

• City 2 - it is in front of the mountains.

• City 3 - it is on the other side of the mountains.

Multiple Choice

Why does city 1 get much less rainfall than city 2?

• City 1 has a lower elevation, and so it has warmer temperatures. The other two cities are colder, so more water vapor condenses in those cities.

• City 1 is farther from the ocean than the other two cities.

• City 1 is on the other side of the mountains, which block most of the water vapor.

The sun is far away from Earth. The sun appears small because it is far away from Earth.
The sun is actually a smaller star. It looks bigger and brighter to us on Earth because the sun is the closest star to Earth - the only star in our solar system.
There are stars out in space in every direction. During the day we can't see them, because the sun's light blocks or overwhelms the light of all other stars - because it is closer than they are.

Multiple Choice

• The baseball will appear larger than it originally did.

• The basketball will appear smaller than it originally did.

• The basketball will appear larger than it originally did.

• Both the basketball and the baseball will look smaller than they originally did.

Multiple Choice

The Earth is always moving.

As the Earth rotates (spins), we have day as we face the sun, and it's night as we face away from the sun.




We see different constellations (stars) in the sky as the Earth orbits around the sun, because we face different areas of space as the Earth revolves.

​In the picture it is night, because the side of the Earth where the red person lives is facing away from the sun. As the Earth rotates, it will become day in about 6 hours!

In the picture (March 7th at night) we can see that right now the Earth is facing towards Leo at night. In six months we will see the stars of Pegasus instead. On the same day every year, we will see the same stars of Leo - on March 7 2025, 2026, 2027...

Multiple Choice

Why does day and night repeat every 24 hours?

• 24 hours is how long it takes the Earth to complete one rotation on its axis.

• 24 hours is how long it takes the Sun to make a trip around the Earth.

• 24 hours is how long it takes the Earth to make one full orbit around the Sun.

• 24 hours is how long it takes the Moon to orbit once around the Earth.

Multiple Choice

Mr. Weaver looks up at the sky on March 7th, and sees many constellations - including Leo! When can he expect to see the constellation Leo again?

• Every day on the same year.

• Every 6 months.

• On the same day every year.

• Never.

Multiple Choice

Mrs. Tillery sees the stars of Pegasus in the sky during September! When can she expect to see this constellation again?

• Every day on the same year.

• Every 6 months.

• On the same day every year.
