Connecting the Parts of the Study Site
The purpose of this resource is to help students articulate and integrate their existing knowledge about the air, water, soil, and living things by viewing them as interacting parts of a system. 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 ch

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
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.
A First Look At Phenology
The purpose of this resource is to increase students' awareness of the qualitative changes in plants during green-up and green-down from which they will be collecting quantitative leaf change data, and to develop an understanding of the patterns and differences among plants at the same location. Students will observe, compare, and classify plants during green-up or green-down and then make inferences based on the patterns they observe.
Spatial Climate Analysis Service
This web site provides access to high-quality spatial climate data sets. The site provides: up-to-date and historical monthly climate data sets and graphics for the continental United States, related papers and presentations, as well as hard copies of maps for purchase.
Idaho Climate Summaries
This site provides climate summaries from one-hundred and fifty two regional stations throughout Idaho. The extensive climate summaries include datasets, tables, descriptions, and maps particular to each region.
Hurricane Katrina Impact Studies
This website is a cooperative research project between the U.S. Geological Survey (USGS), NASA, the U.S. Army Corps of Engineers, and the University of New Orleans. The goal of the project is to investigate coastal change that occurred as a result of Hurricane Katrina. The site includes aerial video, still photography, and laser altimetry surveys of post-storm beach conditions that were collected August 31 and September 1, 2005 for comparison with earlier data. The comparison data can be used to

Developed for third grade. This activity is fairly straightforward and simple. Each student will grow one to three plants from various beans that are placed in a bag. As the plants grow, students will observe how the appearances change daily, and then again over a longer period of time, such as two weeks. Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the
Human Resource Management
Human resource or manpower planning is of great important in the general development and growth of organizations. Thus personnel and Human resources experts, managers and practitioners have now made it known to management that adequate attention be given to it with a view to ensuring better use of other resources especially capital. Organisations have also realized that with increasing competition and complexity in business, more time should be devoted to effective human resources planning to ac
Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.
How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change. View the color of the peak of the spectral curve.
Inside Caitlin's Head
In the 1830s, George Catlin (1796–1872) packed his paintbrushes and trekked through remote Indian country in the Great Plains. Committed to documenting traditional Native culture, he visited more than 140 tribes and painted more than 325 portraits and 200 scenes of American Indian life. Catlin's prolific works, both his art and his writings, illustrate Indian cultures on the precipice of radical change—change that would come with U.S. expansion into tribal territories. In this lesson, stude
Multiple Coin Toss Model
The EJS Multiple Coin Toss model displays the result of the flipping of N coins. The result of each set of coin flips is shown by the image of the pennies on the screen and the complete results of the tossing experiment is shown on a graph of the cumulative probability of heads. The number of coins flipped, N, and change the "fairness" of the coin by setting the probability of a "heads" result, p, can be set via text boxes.
Ask Dr. Global Change
This site offers a searchable collection of answers to questions about global warming, ozone depletion, greenhouse gases, and other issues related to climate change. Students can also submit questions of their own and explore related links.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy. The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Body With Thruster Model
The Body with Thruster Model shows the motion of a disk with an attached rocket engine. You can drag the engine to change its distance from the center of the disk and you can adjust the thrust of the rocket engine using sliders. The mass of the rocket and its connecting rod are assumed to be negligible. The trajectory of this single-body model is intuitively challenging and difficult to visualize.
Radioactive Decay Distribution Model
The EJS Radioactive Decay Distribution Model simulates the decay of a radioactive sample using discrete random events. It displays the distribution of the number of events (radioactive decays) in a fixed time interval. If each event is assumed to occur independently and spontaneously with a constant probability, the resulting distribution if the Poisson distribution. You can change the initial number of nuclei, the decay constant and the time interval for the event distribution.
Radioactive Decay Model
The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot.
