The Battle of Oriskany: Blood Shed a Stream Running Down

(Complete Item Description)

Abstract:: tells how long-standing prejudices and the Revolutionary War unleashed massive bloodshed among inhabitants of New York's Mohawk Valley. Located in rich farmland and at a strategic point in a fur trade route, the valley had been settled by European immigrants who had prospered from productive farms and lucrative trade.

Can You Catch the Water?

(Complete Item Description)

Abstract:: Students construct a three-dimensional model of a water catchment basin using everyday objects to create hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human-made activities. Students discuss how engineers design structures that impact water collection, and systems that clean and distribute water.

Fresh or Salty?

(Complete Item Description)

Abstract:: Between 70 and 75% of the Earth's surface is covered with water and there exists still more water in the atmosphere and underground in aquifers. In this lesson, students learn about water bodies on the planet Earth and their various uses and qualities. They will learn about several ways that engineers are working to maintain and conserve water sources. They will also think about their role in water conservation.

Stream and Pond Field Trip

(Complete Item Description)

Abstract:: Streams and ponds offer good opportunities for comparative studies of biological communities. This exercise describes techniques for sampling aquatic organisms and quantifying habitat features that influence the kinds of organisms found in aquatic habitats. Inexpensive home-made alternatives to commercially-made sampling gear are described. Methods of analyzing community patterns and relating them to abiotic factors are discussed. The comparative approach can be used to contrast various aquatic environments; for example, polluted versus unpolluted streams, ephemeral versus permanent streams, headwater versus downstream reaches, pools versus riffles within a reach, shallow versus deep ponds, or surface versus bottom waters within a stratified lake.
