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.
Striking a Solar Balance by NASA
A short video by NASA discussing how the solar and thermal energy balance effects climate change and global warming. for more information see: http://www.nasa.gov
Wireless Sensor Networks for Ecology
Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals -- even multiple times per second -- over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively
UCSD Organic Lab: Extraction
Training video for organic lab technique.
Thermography allows the investigator to create a 3 dimensional image based on infrared emissions from tissue. Warmer tissues show up as yellow and white, whereas darker colors represent cooler structures. Malignant tumors are metabolically active and appear yellow and white on the images. Metastatic melanoma in left inguinal lymphonodes - metastatic melanoma in left leg -Prof. Camillo O. Di Cicco, MD
Vision and Challenges
This video presents the history of Grid development, an overview of the European Union Akogrimo research project, its visions and challenges in the development of a Next Generation Grid.
Lines of Force
"Lines of Force" opens with footage of a dramatic explosion. For most of the piece, the screen is divided, into a triptych at first, and slowly into horizontal and vertical bars. Electronically manipulated footage shows a man walking, a marching band, ferns, cartoons, a window, and a train arriving on a set of tracks. The naturally occurring lines in the array of images presented mirror the electronically created bars and lines that divide the screen. Natural scenes provide a respite from the fr
Microbe Lab (MWV13)
MicrobeWorld visits the Marian Koshland Science Museum for "Microbe Lab,” a free day of activities for the general public. In this episode we interview Erika Shugart, deputy director of the Koshland Museum, about "Microbe Lab” and the Crack Koshie’s Curious Case: A Disease Detective Mission activity. Next, we talk with Nagla Fetouh, Education Program Manager for the Koshland Museum, who led a disease exchange activity that teaches people about ways to control the spread of infectious disea
