mosses and liverworts
Non-vascular plants have no true roots, leaves, stems, or flowers. They also have no internal circulatory system for bringing water to the various parts of their bodies. Therefore, non-vascular plants are typically found in very wet places. This video gives a brief overview of two non-vascular plants, mosses and liverworts. Run time 0:50.
3D Animation of a Heart Attack
This 3d medical animation illustrates the story of a heart attack from a blocked coronary artery due to th inflammation of blood vessels. Beginning with damage to the endothelial arterial wall, the animation shows how a white blood cell entering the wall of the artery changes into a macrophage, grabbing and digesting cholesterol. As the cell does its job, it transforms into a foam cell, which, unfortunately, becomes part of the plaque within the blood vessel wall. Ultimately, over a period of
Sid the Science Kid - You Look Different Song
In this music video, the teacher sings about plants and how they grow. Lots of images of plants growing are shown throughout the video. The kids close with the observation that things grow very slowly. Run time 02:25.
The Needs of a Plant Song
This video is a catchy song that describes what plants need to grow. It itemizes all of the needs and shows pictures of each need. Lyrics are shown on the screen throughout the song. Run time 1:04.
Paper Towel Plants with Curious George
This video from Curious George shows students helping bean seeds sprout (germinate) outside of soil by meeting their essential needs for moisture, temperature, air, and light. The children place the beans and a wet paper towel inside a zippered plastic bag and leave them undisturbed in a warm, well-lighted place. After two weeks, the students return and observe that the beans have sprouted and, like apple seeds, will one day grow to be fully developed plants. Run time 01:26.
In search of blue oceans
First came the book and now there is an institute in the making. The international bestseller, ‘Blue Ocean Strategy’ written by INSEAD professors W. Chan Kim and Renée Mauborgne, sold more than a million copies in its first year of publication and is being published in a record-breaking 39 languages. Although there are no plans for a follow-up book at this stage, INSEAD is currently setting up the INSEAD Blue Ocean Strategy Institute. In a rare interview, Kim and Mauborgne told Knowledge th

Mrs. Matthews Centers for the week of September 27
The students in Mrs. Matthews science class have been studying plants this week. They have been learning the parts of a plant, parts of a flower, parts of a seed, and various jobs a plant has. The students work through six centers throughout the week. The centers include (1) an art activity about pollination (2) an A.R. book about pollination (3) several interactive websites about the growth of plants and how plants respond to light and gravity (4) an art activity about the life cycle of a
"Hiawatha's Photographing" by Lewis Carroll (poetry reading)
Many of Lewis Carroll's parodies are so good that the originals are now forgotten. Hiawatha, though, is too robust for that. What this parody shows is that the verse form works even better as comedy. http://people.virginia.edu/~ds8s/carroll/hia.html http://en.wikipedia.org/wiki/Lewis_Carroll "Lunar caustic" is silver nitrate. My only opportunity ever to use this nearly useless scap of knowledge - as useless as the little-known fact that most tortoises die of diphtheria - was when a Italian d
The Color Song
This video shows the primary colors and how to spell each color. Students will be engaged by the voice of children their own age. Also the song is simple and can help build associations between the word and the actual color. This is great for a preschool or kindergarten classroom.
Transport of Water and Salts in Plants - Part 1
This is part 1 of a short, animated video (03:37) that offers information about the transport of water and salts in plants from the roots to the stems.
Inside a Solar Cell
In this interactive activity adapted from NOVA Online, learn how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, antireflective coating, and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight. No audio.
The Effects of Green House Gases
Methane, water vapour, nitrous oxide and ozone are the green houses
gases, which exist in the earth’s atmosphere. They absorb thermal
radiations that are breathed out by the earth’s surface and reflect it
back to the earth, thereby serving as a blanket preventing the earth
from heat loss and keeping temperatures constant and perfect for animals
to live, and plants to grow.
For years now, rising temperatures have been a particularly hot topic

Basics of Entrepreneurship: Why Start-ups Fail at Marketing -- and Possible Solutions
Why do more than half of all start-ups fail? Because they bungle their marketing, according to Leonard Lodish, a professor of marketing at Wharton and co-author of two books, Entrepreneurial Marketing and Marketing That Works. "The dogs won't eat the dog food is the way venture capitalists describe it," Lodish says. The key lies in how a marketing plan is crafted. In this installment of the podcast series for the Wharton-CERT Business Plan Competition, Lodish explains that marketing plans must t
Industrialist Henry J. Kaiser ran seven shipyards and employed thousands of people. He used an assembly line to build ships, assembling some in less than five days. One image in this collection shows a ship's hull under construction. Another shows a diagram with goals for completing a ship. The workers at the Kaiser shipyards in Richmond, California, produced the most warships in the country during World War II. One photograph shows workers celebrating the launch of one of their ships.
