5 Different Types and How
They Form

2. Objectives
Students will be able to identify 5 different types of precipitation
Students will learn how each type of precipitation forms
Students will research different precipitations in specific destinations using various resources such as the internet, almanacs, books, etc.

3. Rain Rain is a Droplet of Water
When many droplets combine they get to be too heavy for the air to hold
This is when rain falls to the ground
Where is it raining on this map?
Precipitation Forecast

4. Hail Occurs during very intense thunderstorms
Forms from strong updrafts in the storm
Rarely falls when the air temperature is below freezing
How big do you think hailstones can get?

5. Freezing Rain Rain that freezes on the surface of the earth
Forms when the air on the surface is below freezing but there is an above freezing layer of the air closely above that
This is the most dangerous type of precipitation
Why do you think its so dangerous?

6. Sleet Frozen rain drops
Forms when there is a warm layer of air above a thick subfreezing layer
These raindrops freeze before they hit the earth’s surface

7. Snow
This occurs when precipitation stays as snow all the way through the sub layers of the atmosphere
What types of activities do you like to do in the snow?

8. Summary
There are 5 types of precipitation; rain, hail, freezing rain, sleet and snow. Each type has a different way that they form and are all different in their physical characteristics.

9. Activity
In pairs pick one of the types of precipitation and do research using different sources such as; the internet, almanacs and books in a specific destination, ex. Boston, New York, hometowns, etc. Information should include average falling of your precipitation, worst storms and interesting information.
The pairs will then present their findings to the class
