Earth's Outlook from Above
Fifty years after Sputnik, satellites peering down on Earth have become valuable scientific tools to study the global environment and offer much needed insight into the future of our planet.
Be an Ocean Helper
This OLogy activity shows kids that there are simple, but very helpful things they can do to protect the ocean -- even if they live nowhere near the water. The activity opens by introducing kids to Gabby, a future marine biologist who wants to study dolphins. Then it has a checklist of 14 ways kids can be ocean helpers that includes asking for tap water instead of bottled water and leaving plants and animals where they find them.
Wear a Chimp on Your Wrist
The OLogy activity offers an interesting twist on the study of DNA. Students use colored beads (or gumdrops) to create a bracelet that's based on a section of DNA code. The two strands of the bracelet are then twisted together into a double helix. They can choose to recreate DNA code from a list of favorite plants and animals that includes a monarch butterfly, a chimpanzee, a sunflower, and a brown trout. The activity includes illustrated step-by-step directions.
Winter blasts and delays in the U.S.
A Winter storm hits the Northeast U.S. coast blanketing much of the area in snow and causing travel delays up and down the coast. Deborah Lutterbeck reports.
Can Public Health Researchers and Agencies Reconcile the Push From Funding Bodies and the Pull From
Responding to growing impatience with the limited application of research findings to health practices and policies, both funding bodies and communities are demanding that research show greater sensitivity to communities’ perceptions, needs, and unique circumstances. One way to assure this is to employ participatory research—to engage communities at least in formulating research questions and interpreting and applying research findings and possibly also in selecting methods and analyzing dat
Bio Mechatronics
Biomechatronics is a contraction of biomechanics and mechatronics. In this course the function and coordination of the human motion apparatus is the central focus, and the design of assistive devices for the support of the function of the motion apparatus. Study Goals: The student must be able to:
1. Make a Problem Analysis of a given assignment in the field of the human motion apparatus and its interaction with an assistive device ; Identify the underlying cause [pathology] of the problem as p
Coastal Clash: Understanding Private Property Rights
"Coastal Clash" is a one-hour documentary focusing on the urbanization of California's coastline. The activities and lesson plans for the film "Coastal Clash" target students at the high school level and align with the California State Standards for Government. Students will study the concept of "private property" and the Fifth Amendment, analyze arguments, and evaluate evidence to develop their own opinions.
AstroGrid as an e-Learning Environment
We present the concept of the Virtual Observatory through the AstroGrid project, which is a Virtual Organization making intensive use of the Internet to produce a working data-grid for Astronomical applications.
AstroGrid has implemented a series of tools which facilitate collaborative work such as news, forum and discussion pages, all of them inspired by the open source and licensing philosophy.
Additionally we explore how such an Astronomical Grid project can be used in the future as an e-Le

Un modèle d’élève par l’analyse statistique implicative. Prise en compte du contexte algébri
Le modèle d’élève que nous construisons cherche à donner une représentation fine des compétences cognitives des élèves dans le domaine de l’algèbre. Il se fonde sur les micro-actions enregistrées dans le micromonde Aplusix. Ces actions étant de niveau très fin, nous devons reconstruire les connaissances à un niveau plus abstrait : non pas une action isolée mais un ensemble d’actions « similaires » apparaissant dans un même contexte. Nous utilisons pour cela l’analyse sta
Structuring and merging Distributed Content
A flexible approach for structuring and merging distributed learning object is presented. At the basis of this approach there is a formal representation of a learning object, called attribute structure.
Attribute structures are labeled directed graphs representing structured information on the learning objects. When two or more learning objects are merged, the corresponding attribute structures are unified, and the unified structure is attached to the resulting learning object.
Songs
Suggestions for including songs into the study of Italian.
Prescribed Novel 2 - Gli Occhiali dOro
Information and headings under which to study Giorgio Bassanis novel "Gli Occhiali dOro", including suggestions for discussion of themes and essay writing. A good knowledge of Italian is required to read the novel in the original.
Derivation of Knowledge Structures for Distributed Learning Objects
Knowledge space theory (Doignon & Falmagne, 1985; Albert & Lukas, 1999; Doignon & Falmagne, 1999) offers a rigorous and efficient formal framework for the construction, validation, and application of e-assessment and e-learning adaptive systems.
This theory is at the basis of some existing e-learning and e-assessment adaptive systems in the U.S. and in Europe. Such systems are based on a fixed and local domain of knowledge, where fixed means that the domain does not change in time and local ref
Harnessing Wind
This lesson introduces the ways that engineers study and harness the wind. Students will learn about the different kinds of winds and how to measure wind direction. In addition, students will learn how air pressure creates winds and how engineers build and test wind turbines to harness energy from wind.
Floodplain Modeling
Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.
Is That Legal? A Case of Acid Rain
The goal of this activity is to understand how techniques of persuasion (including background, supporting evidence, storytelling and the call to action) are used to develop an argument for or against a topic. Students develop an environmental case study for presentation and understand how a case study is used as an analysis tool.
