Inside Caitlin's Head
In the 1830s, George Catlin (1796–1872) packed his paintbrushes and trekked through remote Indian country in the Great Plains. Committed to documenting traditional Native culture, he visited more than 140 tribes and painted more than 325 portraits and 200 scenes of American Indian life. Catlin's prolific works, both his art and his writings, illustrate Indian cultures on the precipice of radical change—change that would come with U.S. expansion into tribal territories. In this lesson, stude

The (Ralph) Keeling Curve
After two decades watching atmospheric oxygen levels drop, a Scripps researcher's conclusions about climate could leave one feeling light-headed.
Welcome to the New Normal
Scripps Oceanography research suggests that climate change will require a complete rethinking of water delivery systems in the West. That'll be step one.
Highlight the rationale behind symbolic operations used to solve a linear equation with this tool that displays changes in the graphic and area models of functions as you change the value of each symbolic element.
NASA KSNN Why do leaves change color?
Learn more about why leaves change color and experiment to separate colors within a leaf.
NASA KSNN What is metamorphosis?
As animals grow, their bodies usually change in size and shape. For some, their shape changes very little. For young amphibians, fish, and insects, the change is more dramatic and the young look very different from the adults. This process of change is called metamorphosis.
NASA KSNN What is one-half?
What would our world be like without fractions? Our language would certainly change!
NASA CONNECT Virtual Earth: Using Concept Maps to Solve Problems
In NASA CONNECT Virtual Earth, students will be introduced to Earth system science. They will learn what a system is and how to apply the concept of systems to learn more about how the Earth functions. Students will understand the only way to really comprehend the workings of our planet is to look at the Earth as a whole system. They will also focus on Earth science applications of national priority to expand and accelerate the use of knowledge, science, and technologies resulting from the Earth
"I Wasn't Interested In Living In The United States If I Wasn't Going To Be In The Movement:" Jack O
Jack O'Dell was one of many young black servicemen who returned from World War II determined to change conditions for African Americans at home. Along with veterans, African Americans who had participated in wartime industries and union organizing, and who had experienced improvements in pay and education, became more assertive in their demands for equality. As a member of the National Maritime Union, O'Dell participated in union organizing and challenging racial discrimination. Later, he used h
Voices for Votes: Suffrage Strategies
This lesson involves students in examining primary source documents related to the women's suffrage movement. Students identify methods used to change attitudes about suffrage for women and then create original documents encouraging citizens to vote in current elections.
The Changing Workplace
The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the count
Human Resource Management
Human resource or manpower planning is of great important in the general development and growth of organizations. Thus personnel and Human resources experts, managers and practitioners have now made it known to management that adequate attention be given to it with a view to ensuring better use of other resources especially capital. Organisations have also realized that with increasing competition and complexity in business, more time should be devoted to effective human resources planning to ac
Developed for third grade. This activity is fairly straightforward and simple. Each student will grow one to three plants from various beans that are placed in a bag. As the plants grow, students will observe how the appearances change daily, and then again over a longer period of time, such as two weeks. Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the
View of the vertical stratification of microhabitats in the Mojave desert
The microhabitats within the desert habitat vary by soil type and micro climate. These differences account for the different types of vegetation in each microhabitat.
Vinegar and baking soda
Vinegar is an acid. An acid has a pH less than 7. When baking soda is added to vinegar, bubbles are produced and gas is released. Fizzing, bubbling, and change in smell are all evidence of a chemical reaction. The amount of gas produced using baking soda as an indicator tells you the relative concentration ...
USGS Biological Resources: National Activities
The mission of the United States Geological Survey's Biological Resources Discipline involves working with others to provide the scientific understanding and technologies needed to support the sound management and conservation of our Nation's biological resources. This website contains a comprehensive listing of biological research taking place within the USGS biology branch. This portal provides access to the National Bird Banding Project, the National Park Service flora and fauna database, the
The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States. The need for more comprehensive information on the nature and extent of recent human geomorphic activity led t
Handbook of Emerging Technologies for Learning
This Handbook of Emerging Technologies for Learning (HETL) has been designed as a resource for educators planning to incorporate technologies in their teaching and learning activities. HETL has been developed for a workshop delivered to Athabasca University faculty and reflects several years work with Peter at the Learning Technologies Centre at University of Manitoba. Distance and online universities such as Athabasca, are well positioned to play a bridging role between tradition and emergenc
Introduction to Climate Dynamics and Climate Modeling (CA Textbook)
A comprehensive analysis of all the components of the climate system (atmosphere, ocean, ice sheets, etc) and of all the interactions between them is out of the scope of any course or book. We have thus chosen here to provide only a brief overview of the processes that rule the behaviour of those different ...
