Keeping Cool
Why is the earth's surface cooler at certain times of the day?
The earth’s temperature depends on where the sun is pointing on the earth at the certain time of day. In the early morning the sun’s rays are low and less concentrated and so the surface is less warm.

Its rays hits directly at a 90 degree angle(right above earth)
What is climate change?

What happens after water is evaporated from the heat of the sun?
It rises to the clouds to make precipitation (rain, snow, hail, sleet) to fall back to the earth's surface, beginning the process of once again back into the clouds to do it again.
What fabric that we tested is waterproof?
Vinyl
How does the air move?

At noon
