1. Clouds
4.E.2B.1 Analyze and interpret data from observations, measurements, and weather maps to describe patterns in local weather conditions (including temperature, precipitation, wind speed/direction, relative humidity, and cloud types) and predict changes in weather over time.

2. How do Clouds Form?
The formation of clouds happens when water vapor in the air rises, cools and condenses (or moves from a warm place to a cool place and condenses), forming the water droplets that make up a cloud.

3. What is a Cloud?
A cloud is a collection of tiny, liquid water droplets not water vapor gas.
