Curriculum Guide for the Climate Impacts Map
This Adobe Acrobat (.pdf) guide was produced by the Union of Concerned Scientists to accompany the Global Warming: Early Warning Signs Web site (last mentioned in the March 14, 2001 Scout Report for Science & Engineering). The activities are designed to involve 9-12 grade students in learning about real world issues using recent data. The activities focus on the following four topics: analyzing climate data from a selected city, collecting and comparing data on perceptions of climate with histor
TriNet is a multi-functional seismic network for earthquake research, monitoring, and computerized alerts. The collaborative project among governmental and educational institutions hopes to "create a better, more effective real-time earthquake information system for Southern California." The main focus of the site is the up-to-date availability of earthquake occurrences shown on various interactive maps of California. Other features available include seismic data, emergency response information,
Design a Parachute
After a discussion about what a parachute is and how it works, students will create a parachute using different materials that they think will work best. The students will test their designs, which will be followed by a class discussion (and possible journal writing) to highlight which paper material worked best.
"The Digital Bridges Web site consists of a collection of thirty representative 19th century American bridge engineering monographs, manuals, and documents from the Lehigh University Libraries' Special Collections." The archive provides an interesting retrospective into the beginnings of major bridge projects; the material is complete with high-resolution photographs and text scanned from original books. In addition to historical literature, Digital Bridges also features brief accounts of notabl
Reproductive & Cardiovascular Disease Research Group
The Reproductive & Cardiovascular Disease Research Group is "based in the Department of Biochemistry and Immunology at St. George's, University of London." The Group's "research interests include a number of areas concerned with reproductive and cardiovascular diseases such as trophoblast biology, nitric oxide and apoptosis, with particular emphasis on the role of these subjects in diseases of pregnancy such as pre-eclampsia." This website contains descriptions of protocols commonly utilized by
BioVisa.net: Online Protocol, Journal and Forum Center for Life Science Researchers
BioVisa.net is an online community developed and maintained by life science researchers with the intent to promote information sharing among fellow researchers. The site contains links to research protocols where users can search or browse 1,774 procedures used by other scientists. Registered users can also post comments about any particular protocol. Other site features include online biological journals and forums where researchers can discuss various research topics. After the free registrati
Quick take on unusual plants : not your average garden variety
This one-page document highlights online resources that can help teachers impart ideas of species diversity, biological classification, and adaptations, while developing students sense of wonder and awe of nature s diversity.
Atmospheric Processes : Conduction
After participating in this activity, students will be able to explain the process of conduction using a molecular model and explain that different materials conduct at different rates. They will also be able to identify air as a poor heat conductor (an insulator). The instructor guide contains detailed background material, learning goals, alignment to national standards, grade level/time, details on materials and preparation, procedure, assessment ideas, and modifications for alternative learne
Observe images of different climate zones
This Earth science resource shows students the location of 10 different climate zones on a world map. Red dots mark the location of deserts, highlands, and ice caps, as well as tundra, tropical wet and dry zones, and subtropical areas. Students are instructed to click on each red dot to see a photograph from that region. Each photograph includes a caption that describes its location. Copyright 2005 Eisenhower National Clearinghouse
Science Sampler : Correcting student misconceptions
Before learning any formal science, children try to make sense of natural phenomena on their own. However, several studies have shown that it can be difficult to convince a student to give up a long-held misconception in favor of an accurate scientific explanation. Misconceptions can be confronted through hands-on and minds-on activities. The strategies outlined in this article will foster a climate of inquiry within the classroom.
Like any museum, this website called the Mathematics Museum provides some interesting visuals and explanations of various aspects of its subject, in this case mathematics. For example, the Fractal 3D Gallery includes video footage of 3D fractals and an FAQ section that provides some basic information on fractals. The Kodawari house includes some interesting math games and instruction for children as well as more advanced mathematics. Visitors can browse images created using Mathematica software
Natural Resources, the Environment, and Ecosystems
This collection of teacher guides includes: Ecosystems and Climate, Wildlife - Just One Piece of the Picture, Integrated Pest Management, Soil and Ecosystems, Sustainable Agriculture, and The Web of Life - Understanding Ecosystems. Each guide includes a subject overview, objectives, and student activities. By the end, students should be able to understand the effect of climate on ecosystems; the interrelationships of animals with components of their natural ecosystem; how ecosystems benefit from
Quick take on energy sources
Running on empty? Not yet, but national energy decisions may be a bigger issue in our students lifetimes. A number of groups have created appealing web sites to teach young people about sources of energy as well as the environmental and economic pros and cons of relying on them.
Meteor crater map
A Landsat image of the world with crater locations flagged. One can zoom in on any location.
What is this atmosphere that surrounds the Earth? This instructional tutorial, part of an interactive laboratory series for grades 8-12, introduces students to the structure, effects, and components of the atmosphere. Here students investigate the composition of the atmosphere; effects of temperature, pressure, and ozone; the greenhouse effect; and how Earth compares with other planets. Interactive activities present students with opportunities to explore ideas and answer questions about the atm
Observe an exploded star at different wavelengths
This Earth science resource enables students to observe and compare the appearance of the Crab Nebula under different wavelengths. The introduction explains how the nebula is the remains of an exploded star (supernova). It also reveals how temperature variations in the nebula are detected by different wavelengths. Students are instructed to move the cursor across the spectrum to see images of the nebula captured using radio and microwaves; infrared, visible, and ultraviolet light; and gamma rays
