Rodman's Guns
<p><br /></p><p>The five years of the Civil War are quite rightly considered a period of ordnance and artillery experimentation, development, and transition. The work of one man led, in fact, to the casting of one of the biggest guns ever built, even to the present day--a monstrous 20-inch muzzzleloader that fired a 1000 pound solid shot</p>

Runaway in an Unknown Land: The Underground Railroad in Western Pennsylvania
Prior to the Civil War, enslaved people had little chance of securing their freedom. There were rare cases of freedom being purchased by the enslaved individual or by some benefactor. Even rarer was the granting of freedom papers by the master. For those who desired to taste freedom, the choice of running was often the only viable choice. Runaways faced incredible dangers en route including the possibility of capture.

Sorting through astronomical nebulae.
<p>At the turn of the nineteenth century, astronomers using basic telescopes recorded the existence of an amazing collection of nebulae. These appeared as different types of fuzzy gray material. At that time, technology did not exist to separate the nebulae into different categories. This mini lab has selected representative types of each nebulae and the characteristics of each.</p>

Voyage of Discovery: Lewis & Clark explore Louisiana.
Images related to the Corps of Discovery. Most people think of the Lewis and Clark Expedition as one of geographic exploration. However, President Jefferson charged them to study ethnography, biology, zoology, meteorology, botany and geology. They were required to make detailed maps of their travels and keep a journal about their experiences. Sculptures, paintings and other forms of artwork have been included to illustrate the many interpretations of Lewis and Clark.<br />
