This is a series of computer animations which demonstrate all the possible combinations of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another and the values of these properties determine the state of the gas. In a scientific manner, we can fix any two of the fou
Soil Science and Technology Home Page
This site looks at soil fertility, nitrogen in soil, soil chemistry, soils as electrical systems, soils as filters, soil physics and particle sizes (silt, sand, and clay), microorganisms in soil, nutrients that plants need, soil morphology, judging soil by feel, structures and shapes of soil, and soil profile images from Arizona, Florida, Michigan, and other states. Learn how soil is formed and how long it takes to create an inch of soil.
Investigating the Climate System: Weather
This activity helps students learn how to find, interpret, and describe weather data. Students learn also about drought, flooding, wind and dust storms, hurricanes, and lightning, as well as the Tropical Rainfall Measuring Mission (TRMM) satellite -- the information it provides and why that information is important.
Image Composite Explorer
The Image Composite Explorer is designed to be an easy first step into the realm of Earth system science, image processing, data analysis, and satellite remote sensing via your Web browser. Click to read About ICE and the rationale for its design; for an in-depth tutorial, read the ICE Users Guide; or jump right in to the Channel Islands example if you prefer to learn using a hands-on approach. A Teacher’s Guide is available for educators who wish to use ICE in their classrooms.
Engineering Design Challenges
This site presents challenges faced by NASA engineers who are developing the next generation of aerospace vehicles. The challenges: thermal protection systems, spacecraft structures, electrodynamic propulsion systems, propellers, and personal satellite assistants. Students design, build, test, re-design, and re-build models that meet specified design criteria, using the same analytical skills as engineers.
Stromatolite Explorer: Investigation of a Microbial Mat Community
The Stromatolite Explorer video describes an imaginary voyage inside a microbial mat. This Teacherʼs guide contains a more detailed explanation of a number of the concepts discussed in the video, including the graphs presented in the video. The animated video takes students on a journey through a microbial mat. The assigned mission is to probe a microbial mat by following an imaginary 0.10 mm stromatolite explorer as it descends through the layers. On its route, the vehicle takes chemical readi
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
Ten Activities to Consider Before Developing Your First Online Course
Many educators have asked me what they can do to prepare before they formally begin to develop an online course. Becoming familiar with the online learning environment and knowing how to create web pages can give you a head start in developing your course.Consider preparing with one or more of the 10 activities presented.
Rainbow Spelling (Kinesthetic Approach to encoding)
The following lesson requires the students to spell words containing learned phonemes using a visual and kinesthetic learning approach.
Genome Variation at the Basepair Level - Prof. Aleks Milosavljevic
Insights into cancer biology from the study of base pair-level changes in coding sequences. Genotyping vs. resequencing. Identifying cancer-related genes using association studies. Use of next-generation sequencing technologies to map chromosomal aberrations in cancer genomes. PCR-based resequencing vs. array-based enrichment. Using recurrence, pathway enrichment, and other signatures of positive selection to identify "driver" somatic mutations involved in cancer progression. Part of the Compute
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.
Radioactive Decay and Absolute Age Determinations
This site provides access to a number of visual resources and supporting material illustrating the concept of radioactive decay and its central role in radiometric dating. Visualizations include diagrams, graphs, static illustrations and photos. Resources found on this site are suitable for use in lectures and classes and may also be used as the basis for labs or other activities.
Martin Van Buren's "Return to the Soil"
is a curriculum-oriented site using the home, named Lindenwald, the eighth President moved to after his term in office to introduce a discussion of Van Buren and his times. The site contains photos and drawings of Lindenwald as well as discussions how Van Buren interacted with other political leaders of the day, like Andrew Jackson and John C. Calhoun. The site offers many questions and suggestions for student assignments.
An American Success Story: The Pope House of Raleigh, NC
tells the story of Manassa Pope, the first black man to receive a medical license in North Carolina (1886). After practicing medicine and helping establish a drug store and insurance company in Charlotte, Pope moved his family to Raleigh. There he continued his medical practice, built an elegant house (equipped with the latest technologies) located in the best place allowed for a black family in a segregated city. He later ran for mayor.
Boston's Arnold Arboretum: A Place for Study and Recreation
provides readings, maps, and lesson ideas about the first arboretum in the U.S., which opened to the public in the 1880s. This site, though focused on a place devoted to the study of trees, can help students learn how 19th-century urban conditions influenced the development of parks and how to research the history of parks in their own communities.
Guilford Courthouse: A Pivotal Battle in the War for Independence
looks at this battle?how it was fought; how its outcome was characterized, including reports from both General Nathanael Greene and Lord Cornwallis; and why it was important. About 1,700 Continentals (three-year enlistees in the regular army) and 2,700 militia (mostly farmers who were nonprofessional temporary soldiers called up for short periods of service during an emergency) fought against the redcoats near this North Carolina town of fewer than 100 people.
Backward to the Future
Oral histories not only help us to recall important memories, but when told to children in the form of storytelling, they also provide a connection to the real world and give children a place within their own community. Oral histories help to explain events in one's life while providing an account of the time remembered. In this lesson, students watch a video of a personal history and learn the difference between primary sources and secondary sources of information. They learn how technology and
Climate reconstruction using Foraminifera in Deep Sea Sediments
This Wright Center for Science Education lesson plan (PDF) uses pasta as an analog to teach students how deep sea sediments are collected and analyzed to identify different foraminifera species in order to interpret global paleo temperature change. It includes National Science Education Standards as well as background information and images, a list of materials needed, a step-by-step photo-guided walk-through of the activity, evaluation questions, and reference list.
What good is Beowulf?
High school students can follow the English language's evolution in Beowulf and The Canterbury Tales, and they can focus on words and their meaning as they compare translations.
Two paths to knowledge
For students who always finish their class work early or want more information than you have time to give, try curriculum compacting.
