The magnificent rings of Saturn
In 1610 Galileo observed the rings of a planet later to be named Saturn; with those rings Saturn became one of the wonders of the solar system. Saturn's ring system comprises seven major sections. The elaborate structure of rings is attributed to the gravitational effects of nearby satellites. The rings are made primarily from water ice; however since pure water ice is white, the colors are thought to be caused by contaminants such as rock or carbon compounds. Read more about Saturn's Magnificent Rings on this website.

The Gömböc and the sphere
The Gömböc is the first known homogeneous object that has one stable and one unstable equilibrium point, and thus has two equilibrium points altogether on a horizontal surface. It can be proven that no object exists with fewer than two equilibrium points. The Gömböc self-rights spontaneously. The Gömböc and the sphere are closely related; the Gömböc is the most sphere-like body because the minima of both is equal to one. The Gömböc shape is very sensitive because small changes can disrupt its unique properties. Because of its sensitivity this shape is almost never found in nature. However, some turtle shells are considered to be imperfect versions of a Gömböc-type shape. Learn more about the Gömböc and its unique properties and its mathematics on the website.
Plantfinder
An alphabetic list of more than 4,000 plants are included in the Plantfinder on the Missouri Botanical Garden website.

There is a "problem section" for each plant describing pests and other issues for the plant.
Drilling a square hole
See a video of "almost" drilling a square hole on the How Round is Your Circle website. By removing sections of a Reuleaux rotor, a drill was created that cuts a square hole. You will notice that it does not remove a perfect square, and that small arcs remain in the corners. A short video of another drill in action is also available on the website; click on "Applications of non-roundness."
News on Devonian fish
The Jurassic and the Cretaceous periods featured dinosaurs, but much can also be learned about the "Age of Fishes." Dennis Murphy created Devonian Times with support from scientists at the Academy of Natural Sciences in Philadelphia as a way to learn about paleontology. Descriptions of finding "new" species are written in newspaper article format, which makes the stories seem current and more interesting.
The Green Kingdom
The kingdom Plantae includes all land plants, mosses, ferns, conifers, flowering plants, etc., comprising more than 250,000 species. Plants have been around for a very long time; about 360 million years ago there was a wide variety of shapes and sizes of plants including tiny creeping plants and tall forest trees. The most striking and important feature of plants is their green color, the result of the pigment called chlorophyll. Plants use chlorophyll to capture light energy, which fuels the manufacture of sugar, starch, and other carbohydrates. Without these food sources, most life on earth would be impossible. There would still be mushrooms and algae, but there would be no fruits, vegetables, grains, or any animals which ultimately rely on plants for food. Another important contribution of plants is their shaping of the environment. Plants are everywhere from the tundra, to the rainforest, to the desert. To learn more about the fossil record, life history, ecology, classification, and plant shape and form, go to the Introduction to the Plantae webpage of the University of California Museum of Paleontology.

She kept a written journal of her entire experience complete with descriptive text and imagery that she e-mailed back to her students in Maryland at the end of each day. She reads directly from her journal, and photos illustrate places described in her journal. Four podcasts can be found on the Sun-Earth Day: 2008 website.
Bioluminescence in nature
Bioluminescence is light produced by a chemical reaction that originates within organisms. It is mainly a marine phenomenon. The Bioluminescence Web Page includes information about the basic properties of bioluminescence, as well as images of bioluminescence from space. Watch the angler jellyfish lure fish by light, and see luminescent bacteria in the "milky sea" of the Indian Ocean. Luminescent bacteria occur nearly everywhere. A mailbag section answers questions about bioluminescence.
Physics songs
Songs about physics can help students to remember critical concepts and formulas, but perhaps more importantly they communicate the lesson that physics can be fun! Music helps establish an informal classroom atmosphere in which even shy students ask questions. Songs may also activate a different part of the students' brains. In 1983, Howard Gardner advanced the theory that each person has many different kinds of intelligence. Songs about physics link into the musical aspect of intelligence, helping many students build a richer "knowledge tree" relating to the concept being taught, thus promoting better retention. Listen and learn songs at PhysicsSongs.org.
All about spider myths
House spider myths, weird stories about spiders, myths about identifying spiders, myths about "dangerous" spiders, and other general fallacies are exposed on The Spider Myths Site.

Cyclones, typhoons, and hurricanes
Questions about cyclones, hurricanes, typhoons, and tropical storms are being answered on the Atlantic Oceanographic and Meteorological Laboratory website of the National Oceanic and Atmosphere Administration (NOAA). Tropical storms that travel into the North Atlantic Ocean are called hurricanes whereas those that develop in the South Pacific are called cyclones. Because of Cariolis forces, hurricanes (photo) spiral counter-clockwise whereas cyclones spiral clockwise. Check out the NOAA website for more information.
Watch a shorebird feed
A juvenile red-necked phalarope is feeding. The bird spins on the water surface to generate an up-flow that transports the desired prey toward the water surface. With each dipping event, the bird captures at its beak tip a drop with suspended prey. The high-speed "tweezering" motion of its beak draws the drop toward its mouth, where the prey is consumed and the drop expelled. Watch a movie showing how the bird drinks the water using capillary action on the Science Magazine website; click on Movie s1 and Movie s2 under Supporting Material.

Then count the numbers of pigeons of each color morph at your PigeonWatch Sites and record the colors of courting pigeons. This website is maintained by the Cornell Lab of Ornithology.
Pine cones are female not male
Pine trees have no flowers or fruits, but like other members of the pine family, they produce seeds wedged between scales of a woody cone. Cones are named because of their "cone" shape. Because the cone produces seeds it is a female cone; the male counterpart is not a cone and is known botanically as a strobilus, which produces the wind-blown pollen. Seeds have wings to enable them to be dispersed by wind. Learn more about Pine Cones from the Lovett Pinetum Charitable Foundation website.

Wolfsnail as predator of African snails
The giant African snail (Achatina fulica) was introduced into Hawaii as a garden novelty; however, it soon became a major pest in farmer's fields of crops. Then, the rosy wolfsnail (Euglandina rosea) was introduced to prey on the giant African snail. Unfortunately, the wolfsnail preferred the small native Hawaian snails and fifteen to twenty of the native snails in one island (Oahu) became extinct. Government experts are now seeking ways to control the wolfsnail to preserve native Hawaiian snails. To learn more, and see a video of a snail being devoured, check out the Rosy Wolfsnail web page on the Florida State University website.
Where is the center of the universe?
There is no center of the universe! According to the standard theories of cosmology, the universe started with a "Big Bang" about 14 billion years ago and has been expanding ever since. Yet there is no center to the expansion—it is the same everywhere. The Big Bang should not be visualized as an ordinary explosion; the universe is not expanding out from a center into space. The whole universe itself appears to be expanding and apparently doing so equally at all places. What is the famous balloon analogy? Learn more about the Big Bang theory on the University of California Riverside webpage.
