Busy, Busy, Bees! Honey Bees and Drones
We all know of honey bees! These insects are famous for two things:

have clear hierarchies. The most important member of the hive is the
queen bee. The other kinds of bees are female worker bees which nurse
the eggs and

Workshop 5: Sunlight to Starch
n this program participants will explore how plants get their food. Starting with seeds, which have their own source of food, the program traces the growth of a plant, the development of chlorophyll in its leaves, and the production of sugar (and starch) in a process known as photosynthesis.

Workshop 6: Energy and Ecosystems
In this program, participants are shown that light energy that has been absorbed by plants during photosynthesis and transformed into chemical energy can now be transferred to other organisms. Energy is contained within food molecules such as sugar and starch made by plants, therefore when animals eat plants, or eat other animals, the energy is passed to them. However, the transfer of energy between plants and animals is inefficient and there are energy losses.

A Human Story of Computer Animation
It took 20 years of dreaming, planning and ingenuity to create Toy Story, the world s first computer animated full-length feature film, in 1995. It represented a significant departure from the long-established methods of animation, where artists would hand draw characters frame by frame, and painstakingly incorporate movement and color to complete a feature film. Today, thanks to advances in computing power and ingenious software, there is little separation between the refining of an idea and it

Peachtree Rock Heritage Preserve: The Longleaf Pine Ecosystem
Conservationists know that the Longleaf Pine Forests of the Southern U.S. consist of much more than just its trees. They are complete ecosystems of plants, animals and natural processes including fire, rain and soil mineralization. Estimates show that over the last century, longleaf pine ecosystems have dwindled to less than 3 percent. Once thought to be inexhaustible, these forests were exploited for their lumber and turpentine products. Today, restoring these habitats to pre-settlement conditi

26 - Learning from and Responding to Financial Crisis, Part II (Guest Lecture by Lawrence Summers)
In the second of his two lectures in honor of Arthur Okun, Professor Summers points out that real interest rates have been very low in the current subprime crisis. This indicates that the shock to the economy was more a financial breakdown shock than a disinflation shock. But financial breakdown shocks are not necessarily very harmful to the economy, so long as financial intermediation capital is not destroyed. In a financial crisis like the present one, financial firms are likely to take the st
