One morning, the old wooden dam on the Rappahannock River went up in clouds of smoke. It was a huge thing—ancient and strong, built in layers to tame the river so that the power of the water pushing against it could provide electricity for the town. But it had been years since anyone tapped that power. Now, the dam was falling apart, and it was decided that it had become dangerous. So the Army Corps of Engineers blew it up one morning, and the river was flowing freely again—just as it had in previous centuries. By getting rid of the dam, the river had a chance to go back to being more like it once was. There would be more fish, which would mean more birds, and, really more of everything.
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.
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.
Columbus Day is sometimes called Discoverers' Day. In the spirit of discovery, take some time to learn about the world as it was in the days of the European explorers. You can make a compass, learn about the stars, read about other explorers and discoverers, and find how even our way of eating has changed since the Europeans came to the Americas looking for gold, glory, and, yes, tasty cooking spices.
In 1800, the land held by the new United States was small compared to what was called Louisiana. Louisiana was named for King Louis XIV of France. It was part of a large claimed area in the New World called New France. It stretched from the Great Lakes to the Gulf of Mexico and from the Appalachian Mountains to the Rocky Mountains.

Pocahontas, the Powhatan princess who befriended the Jamestown colonists, married the Englishman John Rolfe in 1614, and is believed by many to have saved John Smith's life—that is what the world knows about the Powhatan Confederacy. Her father, Powhatan, almost alone, united the small, scattered Algonquian tribes of present-day Virginia and Delaware into a 30-tribe group in the late 1500s. We know this group as the Powhatan Confederacy. The Confederacy included 128 Algonquian villages and 20,000+ people at its peak in the early 1600s.
Powhatan and his people welcomed the English settlers in 1607 and helped them survive the first winter here by teaching them how to grow corn and tobacco, providing them medicine, and helping them hunt. But that relationship wasn't to last. Even so, for hundreds of years, people have told the story of a young Powhatan girl who was believed to have saved an English captain's life and established peace for a time between their peoples.
More than 150 years ago, life was turned upside-down for residents in our communities. Stafford County was occupied by Union troops. Fredericksburg changed hands many times between Union and Confederate and was the scene of one of the bloodiest battles of the Civil War. Spotsylvania County had the battles of Spotsylvania Courthouse, the Wilderness, and Chancellorsville. Thousands of men encamped and fought here. Many died here. Our state—even just our own area—has some of the most fought-over ground in the country.
It takes three sets of people—the president, the judges, and the Congress—to make our government work. If the president does something wrong, it's up to the judges and Congress to hold him accountable. If laws are made by Congress that people think are not really fair, the judges can strike them down, or the president can choose to veto them before they become laws. Supreme Court judges are appointed by the president, but they usually stay on long after the president has left office, so as time passes we have a mix of different political views.
Our rivers, lakes, and beaches are beautiful, but are they safe? Every day, the toxic runoff from parking lots, busy roads and quiet subdivisions makes its way into our streams and oceans. Even the oil burning off from cars on the roads gets washed into the groundwater and streams by way of the storm drain every time it rains.
The more houses we build, the more pollution we will add to our environment. Every time we lay down a new parking lot or piece of roadway, there is an impact on our environment.
