DNA interactive chronicle
This site contains four interactive modules that offer teachers a direct look at how information about genetics can be misapplied and misinterpreted within societies. The modules are arranged by topics that focus on Eugenics, Carrie Buck and forced sterilization, Nazi Germany and the elimination of mental illnesses, and a personal account of a woman living with manic depression. Each module is subdivided into additional parts. These parts include images, videos, and simulations of contributions

Jen's home of multicultural math games
This website includes descriptions of three mathematical games from different cultures: Mancala, a counting game from ancient Egypt; Rithmomachia, a 'battle of numbers' board game dating back to 1150 and used by Roger Bacon to teach arithmetic; and To-pe-di, a Native American game of chance. Each game is illustrated. Other terms: geometry, Boethius, Pythagorean number theories, dice sticks. (Includes 5 references)

Gasping for truth : tracking the spread of SARS around the world
This is a lesson plan in which students investigate global responses to fighting the spread of severe acute respiratory syndrome. Students will read a newspaper article to discover what is being done to curb the spread of the deadly disease. Then, students will use a variety of different media to track the spread and other statistics related to the disease. Students will write news reports advising citizens of what to do in affected areas.

Geothermal
What part does geothermal energy play in satisfying energy demands? This informational piece, part of a series about the future of energy, introduces students to heat within the Earth as an energy source. Here students read about the uses, benefits, and limitations of geothermal energy. Articles and information on places around the world that use geothermal energy and geothermal use by schools in Iowa are available from a sidebar. A link to a map of geothermal hotspots around the world is provid

Will it Float?
Student preconceptions are one of the greatest challenges we face as science teachers. This Predict, Explain, Observe, and Explain (PEOE) activity challenges students' preconceived notions about why matter floats or sinks when placed in a liquid. The idea behind this model is to do a demonstration that first confirms students' conceptions followed by a second, similar demonstration that provides discrepant information creating cognitive dissonance. Learning happens as students are forced to modi

Science Sampler : Fossil detectives
Middle school students are transformed into Fossil detectives as they examine the fossil record and use evidence about paleo-environments to develop an understanding of structure and function in living systems and changes over time in Earths history. In this enrichment activity, students work in teams to research an assigned geologic time period. They determine available habitats, food sources and types (animal, plant; woody, herbaceous, etc.), cover sources, methods of getting food, defense, an

Ozone in the atmosphere : ozone production
Why is ozone needed in the atmosphere? In this informational piece, part of an interactive laboratory series for grades 8-12, students read about the structure and function of ozone in our atmosphere. In one activity, students investigate how altitude affects ozone concentration. A discussion of the zones of the atmosphere provides information on the amount of ozone found in each layer. An animation explores the processes by which ozone is produced and destroyed by ultraviolet light. A second ac

El Nino vs. La Nina
This site offers images and animations showing global sea surface temperature (SST) and sea surface height (SSH) during El Nino of 1997-1998 and La Nina of 1998-1999. Images show the difference between the normal SST for that time of year and the actual temperature, clearly showing the higher and lower Pacific temperatures associated with the El Nino and La Nina events of 1997-1999 respectively. Thus the annual cycle and climatology have been removed from the data. Animations use Pathfinder and

Nickel Karate
How can a quarter be removed from the bottom of a stack of quarters without lifting or moving the other coins? This material is part of a series of hands-on science activities designed to arouse student interest. Here students investigate the properties of inertia and Newton's first law of motion. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards.

This virtual manipulative enables the student to form and manipulate shapes on an online geoboard. A virtual geoboard is not limited by the number of bands or the manual dexterity of the student. Additionally, a measure function generates area and perimeter for shapes and, for single bands connected to two pegs, distance and slope. The formed shapes may be colored as a way to sort or enhance them. The activities link offers six exercises that explore area and perimeter or regular and irregular s

Observe some products of a Geographic Information System (GIS)
By combining a short paragraph and six enlargeable maps, this resource explains to students what a Geographic Information System (GIS) is. Introductory text explains that GIS technology enables users to plot multiple data sets onto maps of varying scales. Then six sample maps produced through GIS are provided. Among these maps is one that identifies where energy and mineral resources are located globally and another that highlights and labels the rivers that drain into the Mississippi River. Cop

Building Tetrahedral Kites
Working in teams of four, you and your team will build a tetrahedral kite following a specific set of directions and using specific provided materials. You will use basic processes of manufacturing systems â€“ cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control â€“ to manufacture a complete tetrahedral kite within a given time frame. Evaluation of your project will involve the efficiency of your team as well as your finished product.

4.3 Business and enlightenment: Manchester 1789–99
Childcare, education, working conditions, healthcare, crime â€¦ these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
