As the colonies along the Atlantic coast took shape in the mid-eighteenth century, they became grouped by region: New England, middle, Chesapeake, and southern colonies. Among these regions there were some general similarities, including temperate climates and more than adequate average rainfall, which are critical factors for maximizing agricultural production.
Surplus crops provided the most important exports in all regions except in New England, although what colonists grew depended on

How Was Florida's Coral Castle Built?
From DragonflyTV. Aaron and Tevi are really into exploring the science of places like the Egyptian pyramids and England's Stonehenge. They wanted to figure out how one man moved all of the massive stones to make Coral Castle. They knew he used simple tools so they built a similar set-up, using a fulcrum and lever. Then they built a tripod with a block and tackle system (pulley), also based on the original design, to see if it could lift the huge limestone blocks off the ground. The vi
Characteristics of the Sun
Our Sun is an ordinary star — just one of billions of stars in our galaxy alone. However, as our own star, the Sun holds special status for us and is essential to our existence. The Sun's gravity holds the solar system together, and nuclear fusion within the Sun supplies the energy for life on Earth. Without the Sun, Earth would be a drastically different place. In this video segment adapted from NASA, learn some basic facts about our Sun. Run time 01:28.

Saturn's Mysterious Moons
Note: English subtitles. Some 900 million miles from the Sun in the outer regions of our Solar System orbiting the planet Saturnlies a mysterious world. Enceladus is enveloped in ice. Because nearly all of the sunlight that manages to hit its surface is reflected back into space, its one of the brightest objects in the solar system. It turns out that this distant outpost may harbor subsurface oceans and pre-conditions for life.

The Inner Planet Mercury
Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 88 days. It completes three rotations about the axis for every two orbits. Mercury is bright when viewed from Earth, ranging from −2.0 to 5.5 in apparent magnitude, but is not easily seen as its greatest angular separation from the Sun is only 28.3°. Since Mercury is normally lost in the glare of the Sun, unless there is a solar eclipse, Mercury can only be viewed in morning or evening twilight.
Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt.
