The "A" Train Express

Educator Guide

 

Educator GuideDescription

There are two activities for this NASA CONNECT™ program, Sizing Up
the Clouds and Aerosols Protocol. In Sizing Up the Clouds, students
will set up simulated "clouds" to represent three cloud types and to
estimate the "precipitation" contents of each cloud. In Aerosols Protocol, students will measure the atmosphere's optical thickness-how much of the Sun's light is scattered or absorbed by particles suspended in the air. This activity is part of the GLOBE program and can be downloaded from the GLOBE web site. To learn more
about GLOBE visit http://www.globe.gov.

Instructional Objectives

The student will

  • estimate the "precipitation" contents of three cloud types by using different scientific methods.
  • measure the aerosol optical thickness of the atmosphere
