Using Graphs to Show Connections
The purpose of this resource is to show how graphs of GLOBE data over time show the interconnectedness of Earth's system components at the local level. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.
Comparing the Study Site to One in Another Region
The purpose of this resource is to deepen students understanding of the Earth as a system, and their appreciation for the value of diagrams as tools. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.
Limiting Factors in Ecosystems
The purpose of this resource is to understand that physical factors - temperature and precipitation - limit the growth of vegetative ecosystems. Students observe and record seasonal changes in their local study site. They establish that these phenomena follow annual cycles and conclude the activity by creating displays that illustrate the repeating pattern associated with the appearance and disappearance of seasonal markers.
This webpage is an overview of significant figures and their use in scientific notation. A chemistry tutor in the College of Math and Sciences at a public university developed this overview as one of several study aids for undergraduate chemistry students.

Finding Common Ground
Finding common ground helps students make informed decisions to conserve temperate forests in the United States and central China, habitat of the endangered giant panda. Through classroom activities, on-line simulations, and field investigations students learn about the important role temperate forests play in local and global ecosystems. Action steps culminate in a Class Conservation Action Plan. In the course of this curriculum students locate the biome in which they live, explore a local habi
Decoding the Past: The Work of Archaeologists
This site introduces students to archeology -- the study of material remains to learn about past human experiences. This lesson (Grades 3-8) discusses various challenges of an archaeologist: locating a site that will yield clues about the people who once lived there, conducting excavations, and more. Students identify artifacts from a contemporary setting, describe the function of each artifact, identify methods for dating soil layers, and interpret soil profiles.
Oscillator Chain Model
The EJS Oscillator Chain model shows a one-dimensional linear array of coupled harmonic oscillators with fixed ends. This model can be used to study the propagation of waves in a continuous medium and the vibrational modes of a crystalline lattice. The EJS model shown here contains 31 coupled oscillators equally spaced within the interval [0, 2 pi] with fixed ends.
