    • Clouds and What They Mean
Objective:The objective is to teach my students the general knowledge of clouds. That includes the different types and what each one does.


I will have the students do a worksheet that will test them on the different types of clouds.

I will also create a test or quiz that will test them on the content of the power point. Also, if they can determine the differences between each of the different clouds.
