What kinds of people settled the new lands of America? They had their own ideas about laws, religion, and what makes a good government. They were, in a word, independent.

In 1776, England was far away, and people on this side of the Atlantic were heartily sick and tired of paying taxes on top of taxes to finance England's empty treasury. They were tired, too, of losing money by having the Crown interfere with their trade overseas. The men in the assemblies shouted that King George was a tyrant, so the King's men stopped the assemblies. When they still protested, the King brought in the army, making the colonists put them up in their houses. Any crimes the soldiers committed against the colonists were handled in the King's court by the King's judges.

Cells make up you, your friend, your hamster, and your mom's broccoli surprise. If it's alive or ever was alive, it is made of cells. Space scientists looking for life on Mars are trying to find microbes made of simple cells—not little green men—and biologists who search for cures to diseases work with cells. Small as they are, cells determine how life unfolds from its beginning to its end.

Slow, sleepy winter days find many animals curled up in their dens. They sleep warmly through winter, awakening in spring ready to enjoy the renewed Earth. This unusual, deep sleep is called hibernation.

What Is Hibernation?

True hibernation is a very deep sleep. The animal's body temperature drops, its breathing slows, and it is very difficult to awaken. But some animals, such as most bears, do not really hibernate.

Circles, squares, pentagons, octagons, polygons, angles, rays, points, and lines, there are so many names to learn in geometry. They may sound strange and new, but geometry is all around you. Your computer monitor's surface is more or less a rectangle, your pencil is roughly a cylinder, and, viewed from the top, the cable from your mouse to the computer, is a line segment.  Once you start thinking about geometric shapes, you'll find them everywhere.

When creativity is harnessed for useful ends, that is when we get amazing inventions. Can you think of a better computer? Somebody did. Otherwise there would only be a few of them; they would be really slow—and they would take up entire rooms! Or, how about a cell phone? Those were inspired by the communicators on the original Star Trek series.

Virginia educators (and librarians!) are very interested in helping kids realize their potential in the STEM (science, technology, engineering and math) fields. Indeed, Virginia has a history of producing some very inventive people.
