Document: Owl Pellets Lab Abstract: Owl pellets are masses of bone, teeth, hair, feathers and exoskeletons of various animals preyed upon by raptors, or birds of prey.  Pellets are produced and regurgitated not only by owls, but by hawks, eagles and other raptors that swallow their prey whole of in small pieces. Owls feed early in the evening and regurgitate a...

Document: Observing Ecological Succession Abstract: This lesson allows students to witness how ecological communities respond to environmental changes. Succession is often taught with forest growth as the primary example, but in this outdoor experiment, students will be observing communities of insects over time

Document: Carbon Dioxide Sinks and Sources Abstract: Students will use a chemical indicator (BTB) to detect the presence of carbon dioxide.

Document: Species Interaction Field Investigation Abstract: The purpose of this field activity is to observe examples of species interactions in a field setting.

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=490&id=490 Abstract: The release of toxins into the environment and the federal government’s tracking of that using the Toxic Release Inventory (TRI) compiled by the U.S. Environmental Protection Agency (EPA) are the focus of this case study, which uses GIS to explore the potential impacts of the release of such substances. The case was developed for an introductory environmental...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=599&id=599 Abstract:This case explores two-species interactions, especially mutualism, and presents students with a problem, namely, the inconsistent treatment of the concept of mutualism and symbiosis in many textbooks. It begins with a question that students will probably not feel qualified to answer: Is the equation of mutualism and symbiosis in a textbook correct? It then guides students through...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=272&id=272 Abstract: This case is an exploration of the process of natural selection using white clover (Trifolium repens) as an example. In general, two forms of white clover can be found around the world in various habitats. One type is able to produce cyanide in its leaves, while the other is not. This variation within the clover species,...

Document: Valence Graphic Organizer Abstract: Number of valence electrons for the atoms of this group

Document: Chemistry Unit 2 – Finding Patterns Abstract: This unit, Finding Patterns, takes an inquiry approach to understanding the patterns of properties that exist among the elements. These patterns in properties are then linked to the wave-mechanics concept of atomic structure and the quantum atom. Beginning with isotopes and average atomic mass, as a way of understanding the importance of the...
