Meningitis Research Foundation
Based in the United Kingdom, the Meningitis Research Foundation is a charity organization focused on the prevention and treatment of meningitis (and associated infections) through research and public education. The Foundation website describes common symptoms (with photographs); and contains a variety of specific information about meningitis and septicaemia. For health professionals, the site offers "guidance notes and protocols to promote best practice in the diagnosis and treatment of patients
Colorado Water Knowledge
The Colorado Water Knowledge Web site is maintained by the Colorado State University Colorado Water Resources Research Institute. The site allows kids to explore all aspects of water science including general facts, a description of the water cycle, stream processes, Colorado geology and water history, major aquifers of the area, aquatic life in local waters, Colorado water laws and regulations, and much more. Although it isn't graphic intensive, the site does a good job of explaining the wide a
Center for Research in Scientific Computation
The Center for Research in Scientific Computation (CRSC), based at North Carolina State University, aims to "foster research in scientific computing and provide a focal point for research in computational science, engineering and applied mathematics." The Center has developed a teaching experimental laboratory "where students are exposed to experimental design and data collection through demos and actual hands-on experience." The Center's multidisciplinary research addresses topics in scientific
Swedish Museum of Natural History-Department of Vertebrate Zoology: Guide to South American Cichlida
Sven Kullander of the Swedish Museum of Natural History developed the _Guide to the South American Cichlidae_ as "a non-commercial, technical source of information about the systematics, taxonomy and geographical distribution of South American cichlids." The Guide features a Cichlid Names Database containing 469 nominal species and 60 Nominal Genera with search fields for keywords, Genus/Species, Record/Table, Status, and more. The site also offers a phylogenetic tree representing major cichlid
Andreas Vesalius: De Humani Corporis Fabrica
Northwestern University recently launched an online edition of On the Fabric of the Human Body, 16th century Europe's "most detailed and best illustrated atlas of the human body" produced by Andreas Vesalius, whose work changed the course of medical history. Daniel Garrison and Malcolm Hast, who have spent over a decade (and counting) translating the Fabrica, are making their work available online as the translation continues. Readers can now access an annotated translation of Book One -- includ
MEDLINEplus: Medical Dictionary
MEDLINEplus, the consumer health Web site from the National Library of Medicine, had recently added an online version of Merriam-Webster's Medical Dictionary. Added in response to feedback from MEDLINEplus users, the medical dictionary provides definitions, correct spelling, and pronunciation help for 60,000 words and phrases used by healthcare professionals. The dictionary also offers "biographies of individuals who have given their names to the language of medicine." With the addition of this
Pea Soup Ponds
In this activity, students will learn how water can be polluted by algal blooms. They will grow algae with different concentrations of fertilizer or nutrients and analyze their results as environmental engineers working to protect a local water resource.
An introduction to our solar system: the planets, our Sun and our Moon. Students begin by learning the history and engineering of space travel. They make simple rockets to acquire a basic understanding Newton’s third law of motion. They explore energy transfer concepts and use renewable solar energy for cooking. They see how engineers design tools, equipment and spacecraft to go where it is too far and too dangerous for humans. They explore the Earth’s water cycle, and gravity as applied to
Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.
Design a Solar City
Students design and build a model city powered by the sun! They learn about the benefits of solar power, and how architectural and building engineers integrate photovoltaic panels into the design of buildings.
Ring around the Rosie
Students learn the concept of angular momentum and its correlation to mass, velocity and radius. They experiment with rotation and an object's mass distribution. In an associated literacy activity, students use basic methods of comparative mythology to consider why spinning and weaving are common motifs in creation myths and folktales.
Save Our City!
Students learn about various natural hazards and specific methods engineers use to prevent these hazards from becoming natural disasters. They study a hypothetical map of an area covered with natural hazards and decide where to place natural disaster prevention devices by applying their critical thinking skills and an understanding of the causes of natural disasters.
In this activity, students use a variety of materials to design and create headphones that absorb sound.
Can You Catch the Water?
Students construct a three-dimensional model of a water catchment basin using everyday objects to create hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human-made activities. Students discuss how engineers design structures that impact water collection, and systems that clean and distribute water.
Students determine their own eyesight and calculate what a good average eyesight value for the class would be. They learn about technologies to enhance eyesight and how engineers play an important role in the development of these technologies.
In this activity, students act as environmental engineers involved with the clean up of a toxic spill. Using bioremediation as the process, students select which bacteria they will use to eat up the pollutant spilled. Students learn how engineers use bioremediation to make organism degrade harmful chemicals. Engineers must make sure bacteria have everything they need to live and degrade contaminants for bioremediation to happen. Students learn about the needs of living things by setting up an ex
It’s all In the Package
In this activity, students explore the concept of “reducing” solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. They will evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. Students will explore “hydrapulping” an
What Is Energy? Short Demos
Three short, hands-on, in-class demos expand students’ understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, students create paper snake mobiles to explore how heat energy can cause motion. Finally, students determine the effect that heat energy from the sun (or a lamp) has on temperature by placing pans of water in different locations.
Global Climate Change : The Ross Ice Shelf
This video lecture explores the effects of climate change on the Ross Ice Shelf in Antarctica. Slides depict how a large iceberg fell off the Ross Ice Shelf in March 2000. The lecturer describes his expedition to the ice shelf shortly after this event. He describes dives conducted to observe the underwater ecosystems containing krill and jellyfish, and the ocean currents around the icebergs. Facts about the icebergs in Antarctica are presented, and the sensitivity of polar regions to climate is
Understanding Rational Numbers and Proportions
The three activities in this investigation center on situations involving rational numbers and proportions that students encounter at a bakery. These activities involve several important concepts of rational numbers and proportions, including partitioning a unit into equal parts, the quotient interpretation of fractions, the area model of fractions, determining fractional parts of a unit not cut into equal-sized pieces, and equivalence.
