ClimateSim is a fast and simple climate modeling and simulation tool. It is a web app that is freely available to anyone interested in climate science. ClimateSim allows users to model scenarios of greenhouse gas emissions in the current century and simulates the first-order response of the earth system. ClimateSim makes climate simulation accessible in a simplified form and provides an easy-to-use simulation platform for performing virtual climate experiments. ClimateSim is primarily targeted as a science education tool for undergraduate and advanced high-school students in physics, environmental science and related courses. Instructors can use ClimateSim to illustrate climate-change concepts, demonstrate dynamic relationships between climate variables, and assign simulation-based exercises as part of their courses. It is also an appropriate and accessible tool that policymakers, journalists and others can use to get a better understanding and working knowledge of the basics of climate science.

The purpose of this resource is to use a land cover type map to make environmentally sound decisions.

Encyclopedia of STEM education is a free resource with 50,000 problems/solutions covering 13 math subjects, 13 science subjects and 13 engineering subjects for self study learning, classroom teaching, tutoring and teacher training.

Epplets present extended Parsons puzzles. In a Parsons puzzle, the student is presented a problem statement, and a program to implement it, but with the lines in the program scrambled. The student must reassemble the lines in their correct order and eliminate distracters. The tutor provides feedback until the student arrives at the correct solution. Epplets help students construct the algorithm for a problem.

This section explores several hypothetical scenarios of nuclear-weapon detonations on U.S. cities. These scenarios are meant to illustrate the possibilities of such events. Scenarios include a "what-if" scenario of a 150-kiloton nuclear explosion by terrorists on New York City, and the effects of a nuclear accident or "broken arrow" on board a nuclear submarine in San Francisco Bay.

The purpose of this resource is to observe plant green-down and report greendown data to help validate estimates of the end of the plant growing season. Students monitor the change in color of selected leaves of trees, shrubs or grasses.

The purpose of this resource is to observe plant green-up and report data that will be used by scientists to validate satellite estimates of the beginning of the plant growing season. Students monitor budburst and growth of leaves of selected trees, shrubs, or grasses. Species chosen should be native, deciduous, and dominant in your area.

This resource provides guidance on site selection for the GLOBE Atmosphere data collection protocols. Instructions for building an instrument shelter, a snowboard, an ozone measurement station, and a wind direction instrument are included.

The purpose of the resource is to investigate changes in the major land cover types of Study Sites by examining Landsat satellite images acquired years apart.

The purpose of this resource is to develop a classification system for a set of objects and learn about hierarchical classification systems. Any set of objects, such as insects or rocks, may be used as well.

The purpose of the resource is to produce a land cover type map from hard copies of Landsat satellite images.

This website contains a series of hands-on problem-based active learning nanotechnology modules that were developed to be incorporated within undergraduate civil and environmental engineering courses. These activities have been developed using a pedagogical approach called Environments for Fostering Effective Critical Thinking (EFFECTs). This approach uses student-centered learning strategies to promote deep learning, enhance conceptual understanding, and stimulate growth in critical thinking skills. Details associated with this pedagogical approach are also included on this website.

The purpose of this resource is to help students understand the connection between remote sensing, computer imagery, and land cover assessment. Students translate their maps created in the beginning activity into digital code and exchange the digitized versions of their maps with students in another school.

The purpose of this resource is to familiarize students with the importance of perspective and various scales of remotely sensed data. Students create a 3-D model of an area and develop a classification system for the landforms in their model. The maps can then be used to answer certain questions about the environment.

The Online Macromolecular Museum (OMM) is a site for the display and study of macromolecules. Macromolecular structures, as discovered by crystallographic or NMR methods, are scientific objects in much the same sense as fossil bones or dried specimens: they can be archived, studied, and displayed in aesthetically pleasing, educational exhibits. Hence, a museum seems an appropriate designation for the collection of displays that we are assembling. The OMM's exhibits are interactive tutorials on individual molecules in which hypertextual explanations of important biochemical features are linked to illustrative renderings of the molecule at hand.

Why devote a site to detailed visualizations of different macromolecules? In learning about the intricacies of life processes at the molecular level, it is important to understand how natural selection has fashioned the structure and chemistry of macromolecular machines to suit them for particular functions. This understanding is greatly facilitated by the visualization of 3-dimensional structure, when known. So, if static views of molecules (even in stereo) are worth a thousand words, then interactive animations of molecules should be worth much more. Indeed, we have found the types of displays represented here invaluable in gaining an appreciation for the details of key biochemical processes.

As Carl Brandon and John Tooze stated in their classic text, Introduction to Protein Structure:
"Molecular biology began some 40 years ago with the realization that structure was crucial for a proper understanding of function. Paradoxically, the dazzling achievements of molecular genetics and biochemistry led to the eclipse of structural studies. We believe the wheel has now come full circle, and those very achievements have increased the need for structural analysis at the same time that they have provided the means for it."

It is our opinion that structural analysis should extend into the classroom: as students learn about cellular mechanisms it is important that they study the chemistry of the molecular machines involved. These considerations have motivated the construction of the OMM.

The OMM is part of a collaborative effort by faculty and students interested in macromolecular structure-function relationships. The primary authors of some tutorials are students of David Marcey and he serves as author, co-author and site editor, and assumes all responsibility for content. Any criticisms, suggestions, comments, or questions should be sent to him at: marcey@callutheran.edu. All tutorials are copyrighted.

The OMM was started in 1996 for a Molecular Biology class at Kenyon College, where DM was a professor in the Biology Department (1990-1999). The OMM is now developed and housed at California Lutheran University, where DM has been a professor since 1999.

The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were selected because each plant blooms at a different time in the year.

The purpose of this resource is to classify and count the reproductive phenological phases of receptacles on selected seaweed species. Students will classify and count the reproductive phases of seaweed plants within a 1-meter x 1-meter plot in the inter-tidal zone.
