Ferns attached to a forest rock
Ferns have small, branched leaves, not to reduce gas exchange and water loss, but to increase the surface area for spore producing structures. This demonstrates that plants develop certain characteristics for very different reasons.
Architects and Engineers
Students explore the interface between architecture and engineering. In the associated hands-on activity, students act as both architects and engineers by designing and building a small parking garage.
David Gergen at Elon University Convocation
David Gergen, Senior Political Analyst for CNN, talks about current issues the government faces during Elon University's Spring Convocation for Honors April 7, 2011.
The Bracero Program
The government-sponsored Bracero Program was the temporary importation of workers from Mexico to aid the American agricultural economy. This was an important historical event that many Americans are unaware of today. A bracero (from brazo, the Spanish word for arm) was a Mexican worker allowed entry into the United States for a limited time, usually to work on a farm. In 1942, facing an extreme shortage of farm labor workers due to the war, Congress enacted the Emergency Labor Program. It approv
In this activity, students will research a political issue that is highlighted and discussed on the TakingITGlobal website. Students will pick one issue and write a one page satire on the event/issue. Part 2 of the assignment is for the students to create their own political cartoon using Photoshop or similar software.
Explain which fish you would want to be in this school and why.
Induction of Nitrate Reductase in Plant Shoots
A laboratory exercise that uses colormetric assay and corn seedling shoots to study the induction of enzyme activity by a substrate.
Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar
Remote Sensing Interactive: Land Cover Map / Image Comparison
The Land Cover Map / Image Comparison is one of a number of interactive tools being developed to illustrate basic remote-sensing . Here, the user is able to examine a portion of the Chiricahua Mountains in southern Arizona by viewing two sets of images from TM and Modis sensors, and selecting areas within them for closer examination at three magnification levels.
This OLogy activity gives kids a chance to test their investigation skills while learning about daily life for the Incas. Inca Investigation begins with an introduction to archaeologist Craig Morris and the ancient Inca city that his team excavated in the Andes mountains. Then kids are given detailed directions for how to play Inca Investigation, which includes tips to help them better examine evidence. At any time, they can get help, learn how to read a plan, or browse a book about Inca history

" Over the Hump and Jump"- Counting with Transitional Numbers
This computer-animated video provides practice counting with transitional numbers, numbers ending with nine. The video shows the "nine" numbers climbing to the top of a mountain with the "tens" number being the summit. Many examples are given. ( 2:55)
Diversity of leaves
The diversity of land plants can be seen in the diversity of their leaves. Leaves vary by color, vein arrangement, shape, texture, and thickness.
How do I pay?
Op het einde van deze les kun je bepalen met welke betaalmiddelen jij de congestion charge misschien wel zou betalen en met welk betaalmiddel zeker niet.
Plants That Aren't Plants: Mosses and Lichens
Mosses and lichens are not given much attention in introductory biology laboratory courses, in part because instructors lack skills necessary to cover the topic-namely, moss leaf cross sectioning and lichen chemical spot tests. Acquiring confidence in just these two techniques, as well as familiarity with basic terminology, lays a foundation for further investigation.
Slide Right on By Using an Inclined Plane
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.
Plan B: Rescuing a Planet Under Stress and a Civilization in Trouble
The Berkeley Institute of the Environment announces its first annual Distinguished Lecture, featuring Lester R. Brown. Mr. Brown has been called "one of the planet's most important thinkers" and a "guru of the environmental movement." He is founder of the Worldwatch Institute and the Earth Policy Institute, and author or co-author of 50 books related to the environment.
