Your sense of smell
This single-page resource about the sense of smell presents a handful of facts about smell together with scientific illustrations. For example, the resource points out how many odors humans can detect and what scientists still do not know about smell. It also compares our sense of smell to that of rodents. The scientific illustrations are a set of connected, labeled diagrams of the key structures and pathways involved in sensing smell, including the olfactory membrane and olfactory receptors. Th
All lives seek balance : intro to homeostasis
The study of homeostasis reveals that balance within living systems is not peaceful, nor quiet, is filled with change, but does harmonize the interior environment with the exterior environment. Call it dynamic equilibrium, a continuous circle dance of adjustment and correction. Maintaining this balance between a living system's internal conditions and fluctuating environmental (external) conditions is called homeostasis. Illusrates and describes feedback loops.

What Do Parentheses Mean?
Can you help me find ways to figure out what parentheses mean?
Energy Transformation on a Roller Coaster
This webpage offers a discussion of work, energy, and force on a roller coaster as it goes through a loop in the track. It includes an animated image of the roller coaster with appropriate data for each point in the track. A multiple choice practice question using the relevant equations is also available.
Box model (grades 6-8)
This virtual manipulative enables the student to randomly generate data that is displayed on a chart. The chart shows the results of a simulated drawing with replacement from a set of numbers selected by the student. The manipulative can be used to simulate flipping a coin or tossing a die. A pause button stops the simulation. A button for showing theoretical probability places an outline on the theoretical probabilities chart, which allows the student to compare the theoretical and experimental
Walk-through of "Blinky Palermo" with exhibition curator Lynne Cooke
On opening night, February 24, exhibition curator Lynne Cooke leads visitors on a walk-through of the Hirshhorn installation, exploring the evolution of Palermo's aesthetic and the significance of his contributions to postwar painting.
Pushing It Off a Cliff
Lesson 2 will be in the Research and Revise step and will be focusing on the conservation of energy solely between gravitational potential energy and kinetic energy. Students start out with a virtual laboratory, and then move into the notes and working of problems as a group. A few questions are given as homework. A dry lab that focuses on the kinetic and potential energies on a roller coaster concludes the lesson in the Test Your Mettle phase of the Legacy Cycle.
Rubinstein on Game Theory and Behavioral Economics
Ariel Rubinstein of Tel Aviv University and New York University talks with EconTalk host Russ Roberts about the state of game theory and behavioral economics, two of the most influential areas of economics in recent years. Drawing on his Afterword for the 60th anniversary edition of Von Neumann and Morgenstern's Theory of Games and Economic Behavior, Rubinstein argues that game theory's successes have been quite limited. Rubinstein, himself a game theorist, argues that game theory is unable to y
Ion Exchange Chromatography
This website contains an ion chromatography simulator that can be run on-line or can be downloaded. The simulator focuses on separations of proteins using Ion Chromatography. Also included is hyperlinked reference information, an example of a homework assignment using the simulator, and some information on protein structures.(note this is an archived version of this site, as the original has been moved).
RSC.org: UV/Vis Spectroscopy
This video distributed on YouTube is on the basic principles of UV/Vis. Provides a good primer (~5 min), and the top-off look of the instrument is useful in explaining components. A double beam instrument is described.
Scanning Probe Microscopy
Excellent web-resource on scanning probe microscopy accessible to beginners who wish to learn basics of these methods. Descriptions with figures and diagrams introduce atomic force microscopy (AFM), scanning tunneling microscopy (STM) and electrochemical scanning tunneling microscopy (EC-STM). The site also provides an overview of the variety of applications of these methods.
6.5 Monitoring progress This stage of the framework is about keeping track of your progress. Are you using your information literacy skills effectively for your purposes? How do you know? Could you have done things differently: made use of different facilities and expertise, taken more advantage of tutorials, training sessions or local expertise, or recognised that such support would have helped you? Monitoring your own performance and progress needs practice; try to stand back and look at what you are doing as if y

Symmetries and Their Properties-Part 2: Reflections
This is the second i-Math in a four-part series of i-Maths entitled Symmetries and Their Properties. In this second i-Math you will investigate reflection, mirror, or bilateral symmetry. Mirrors can be used to create reflection symmetry. Many objects in nature, such as butterflies, the human body, and many types of leaves have bilateral symmetry. Objects we use every day, such as spoons, chairs, and cars also have bilateral symmetry. In this i-Math, you will learn about the mathematical properti
Newsmaker Highlight: El-Erian on the impact of the Japan earthquake
March 31, 2011 - Pimco CEO Mohamed El-Erian believes Japan will repatriate more funds than the market expects.
4 Fossil fuels
Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth. Is nuclear power a salvation or a nightmare? This unit provides background information to each resource, so that you can assess them for yourself.
Application Letter for a Job
This is a conversation lesson to revise careers agus the requirements which go with them agus the layout of a letter so that the pupils will write their own application letter for a job.

“Dreams in the 20th Century”
Watch video from the April 6 Thinking Out of the Lunchbox event. Barbara Hahn, Distinguished Professor, Germanic and Slavic Languages, spoke on ”Dreams in the 20th Century.” Why write down dreams? Why try to share these strange experiences that determine our nights? Obviously, there is a need to remember and not to forget dreams. So many comekeep reading »
