Middle School Portal: Math and Science Pathways (MSP2)
This activity asks students to determine if the Statue of Liberty's nose is out of proportion to her body size. The activity, from the Figure This! list of 80 math challenges, illustrates how to use similarity and scaling to design HO gauge model train layouts and analyze the size of characters in Gulliver's Travels. It describes the mathematics involved in determining proportion and shows students how to use scaling to enlarge a picture. There are also questions about shrinking a T-shirt and th
The windmill (VM1)
This project requires designing blades for a windmill to be used in lifting weights. The activity involves assembly of the basic windmill as well as construction of, and adjustments to, the blades for optimum performance. Provides knowledge of static and dynamic friction, aerodynamics, and power calculations. Requires an understanding of horsepower and the difference between power and energy.

Hodges Health Career - Care Domains - Model
Hodges’ Health Career (Care Domains) Model provides a conceptual framework upon which users can map problems, issues and solutions across four knowledge domains: Interpersonal; Sociological; Scientific; & Political (Autonomy). The public may also be taught to use the model, enabling engagement, understanding and concordance in planning and outcome evaluation.
Brian Hodges' original notes, a resources page and links (800+) are included. Additional material on health informatics and the potenti
Cotton: Building a Better Plant
Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes: Revealed! takes viewers on a lively, upbeat journey that explores how these plants got to be the way they are and investigates how we can make better use of them in the future. Plant scientists are hard at work--in the lab, in the field and at the computer--to increa

Break the Science Barrier - Richard Dawkins - Part 1 of 3
Break the Science Barrier follows the Oxford Biologist Richard Dawkins as he meets with people who have experienced the wonders of science first-hand. We meet the astronomer who first discovered pulsars, the geneticist who invented DNA fingerprinting, a scientist who discovered a protein that causes cancer, and others. Dawkins interviews famous admirers of science such as Douglas Adams and David Attenborough, and asks them why science means so much to them. We also see how dangerous ignorance of
Crystal Growth Movies
This site, maintained by the Department of Geology and Geophysics at the University of Wyoming, contains four QuickTime videos of actual crystal growth. To access the videos, scroll down to the bottom of the page and click on any of the downloads that are available. These videos enhance understanding of the processes involved in crystallization.
Artificial Intelligence: Natural Language Processing
This course is designed to introduce students to the fundamental concepts and ideas in natural language processing (NLP), and to get them up to speed with current research in the area. It develops an in-depth understanding of both the algorithms available for the processing of linguistic information and the underlying computational properties of natural languages. Wordlevel, syntactic, and semantic processing from both a linguistic and an algorithmic perspective are considered. The focus is on m
General Science
The course focuses on the underlying concepts of science. Content coverage includes the scientific method, measurement in science, the human body, the nature of matter, humans and technology, and safety in science. The content will be presented in themes which in turn will draw upon students' understanding of themselves and their everyday experiences. The self-paced structure of the course will allow students to work through the material at a pace suitable to their individual needs. The course i
Asleep at the Switch: Local Public Health and Chronic Disease
Local health departments generally do a good job of monitoring and controlling conditions that killed people in the United States 100 years ago. Yet noncommunicable diseases, which accounted for less than 20% of US deaths in 1900,1 now account for about 80% of deaths.2 Our local public health infrastructure has not kept pace with this transition. Health departments must continue to handle traditional public
health priorities as well as emerging infectious diseases. They must also increasingly ad
Knots and their uses
A set of questions designed to test knowledge and understanding about common knots, their uses, advantages and disadvantages. The test includes questions on hitches, bends, loops and other commonly used and useful knots. The What Knot? sections also tests you on your ability to choose the most appropriate knot in a variety of situations.
Elementary Mathematics: Times Tables I
Learn and practice times tables. This is the first of two modules and practices the 2, 3, 4, 5 and 10 times tables. It includes multiplication testing, corresponding division exercises and missing-operand exercises as part of a range of different task types designed to develop an all-round understanding of the times tables.
Individual Health Status and Racial Minority Concentration
in US States and Counties
Objectives. We examined whether the positive association between mortality rates and racial minority concentration documented in ecological studies would be found for health status after control for race/ethnicity, socioeconomic status, and region of residence.
Methods. We estimated least squares and probit models using aggregate and individual health status data from the 1995, 1997, and 1999 versions of the Current Population Survey merged with data from the US Bureau of the Census regarding s

It is included for those new to the field who may not appreciate the importance of this technique in biology, who lack the vocabulary to understand the BLAST guide and tutorial or who require a basic rather than a sophisticated understanding of the methods involved. Sections include introduction, premise, terms, general approach, the BLAST algorithm, quantification, gaps, significance, and databases. Users ca
Microbiology Unit
This College level Unit in Microbiology explores microbes on five levels, their architecture, ecology, physiology, lifecycles and pathology. Students will be given an interactive tour of the world of microbes and learn more about their impact on Humans, animals, plants and on the environment in general. They will become aware of pathogenic (harmful) and non-pathogenic (helpful) microbes and develop an understanding of how microbiologists devise methods to study microbes in order to understand th
Optional Barometric Pressure Protocol
The purpose of this activity is to measure air pressure. Students record atmospheric pressure using a barometer or altimeter. Intended outcomes are that students gain an understanding that barometric or altimeter pressure varies and its increase or decrease indicates an upcoming change in the weather. Students also learn that the air has weight. Supporting background materials for both student and teacher are included.
