As part of the unit on political parties the students will compare and contrast the two main parties, the Democrats, and the Republicans.

Digging into our ancestors' past is hard work. Records of human life were not kept millions of years ago. What was life like for cavepeople in the Stone Age? Did Fred Flintstone actually wear leopard skin suits and eat brontosaurus burgers?

As tensions flared between England and Spain, it soon became sensible for England to establish permanent settlements in the New World to rival the Spanish. If nothing more, they could serve as bases from which to raid Spanish ships.

Lucy belonged to genus Australopithecus and the species afarensis, but she also belonged to the the hominid family (hominidae) to which humans belong. Although humans are of the family hominidae, we are not of Lucy's genus or species. We are Homo sapiens. How then, can Lucy be our ancient ancestor if we belong to a different genus and species? It's because humans and Lucy share a taxonomy up to the point of genus and species; there are many shared characteristics, but there are differences and these differences place humans in our own genus and species.

For Neanderthal Man, each and every day was a challenge. What was life like for Neanderthals? How did early humans find food, make clothing, and seek shelter?

With an excess landless population to serve as workers, and motivated, adventurous, or devout investors, the joint-stock company became the vehicle by which England finally settled the Western Hemisphere.

Because there was no written language 50,000 years ago, we do not have much information on how a "modern stone age family" lived, what they ate, where they lived, what they wore, or even what they looked like. Like Fred Flintstone, did they have leopardskin suits, go barefoot, and use a boulder for a bowling ball?

The first joint-stock company to launch a lasting venture to the New World was the Virginia Company of London. The investors had one goal in mind: gold. They hoped to repeat the success of Spaniards who found gold in South America.

People of the Stone Age did not have the luxury of turning on the TV and watching Tim "Rock" Taylor host "Tool Time" or Bob Vilastone giving home-building tips in "This Old Cave." Nor could they dial 911 when a fire threatened them. Rather, they had to invent tools and harness the power of fire. But it was their experiments in tool-making that ultimately led to TV, cell phones, and computers.

Virginia's economic future did not lie with gold. There was too little gold to be found there. Looking for new ways to make its investments pay dividends, the Virginia Company of London began encouraging multiple ventures by 1618. Despite efforts to diversify Virginia's economy, by the end of the 1620s only one Virginia crop was drawing a fair market price in England: tobacco.

Despite his suspicions, Chief Powhatan helped the British settlers through their first winters. But the good relations did not last, and Powhatan was forced to fight.

Although many differences separated Spain and France from England, perhaps the factor that contributed most to distinct paths of colonization was the form of their government.
