Allies and Aliens
In the learning module Allies and Aliens students assume the role of agents from planet Earth who must assess varying degrees of prejudice and misinformation as they visit Web sites from other planets. Because most kids don't think to look for bias or false information online and subtle forms of racism may be difficult to recognize, Allies and Aliens uses the pretense of an evaluation mission to keep players from guessing its true purpose right away. The mission is divided into two parts. On Day

Stereotypes of the French
This unit comprises four major lessons which are distinct yet cumulative. In the first lesson, the students will lay the groundwork for their examination of French stereotypes by generating those stereotypes themselves. They may draw, write, or find examples of what they think are "typical" French things. In the second lesson, they will be required to change perspective -- instead of being the examiners, they will be the examined culture. Students will look at various examples of stereotypes of

Precipitation Protocols
The purpose of this activity is to determine the amount of moisture input to the local environment by measuring rain and snowfall and to measure the pH of precipitation. To do so students use a rain gauge and a snowboard to measure the daily amount of precipitation. Special pH measuring techniques for precipitation are used to determine the pH of rain and melted snow. Intended outcomes are that students will understand that precipitation is measured in depth and this depth is assumed to apply to
