Sound travels in waves, much like those that roll across the ocean, to give our ears information which we may or may not understand. These sound waves are very much like those that light uses, too, whether it’s the (mostly) steady flow of light from the Sun or spectacular 4th of July fireworks which combine light and sound for an amazing night of excitement.  But sound waves are also used for communication amongst humans and amongst other life forms to tell about important things (Predator coming!) and not so important things (the bus is late—again!).

Twenty years before Jamestown was founded, over 100 women, men, and children came to Virginia to try their luck at starting a colony. They arrived on the stormy shores of what we know now as North Carolina. They were not the first to land there. Two years before, another group of colonists, all men, gave up trying to settle Roanoke Island and sailed back to England. The supply ships arrived too late to save the abandoned first colony, but they left behind fifteen soldiers to mind the fort who soon vanished into the wilds, driven off by an Indian attack.

What is a knight?
The simple answer would be a soldier who fights on horseback while wearing armor, but there’s much more to being a knight.

Who were the first knights?
There have been soldiers on horseback for thousands of years, but what we think of as medieval knights first came into being during the time of King Charlemagne (Charles the Great). Charlemagne was a Frank (Frenchman). His knights kept him safe in battle and won him many victories. Chanson de Roland (Song of Roland) was written about Charlemagne’s most famous knight.

You know, because you've been told, that the Earth revolves around the Sun. You also probably know that planets other than our own have moons, and the way to test to see whether or not something is true is by experimenting. Thousands of years ago, these things were not widely known. The heavens above were anyone's guess, and the way things were was just the way the gods had made them. It was felt there was no need to truly understand them or put them in any kind of order.

The tribes who lived in the Western Hemisphere before the coming of the Europeans were as different from each other as the countries that came to claim their lands. The many stories of the people who farmed, hunted, and herded in the plains, forests, deserts, and hills of what we call North America tell how they saw the Universe and the wisdom that they found in Nature.
