Environmental Science!

As we begin the work of the 2nd semester, we direct our attention toward the environment and on our impact on our planet.  Humans have impacted ecosystems as long as humans have existed.   Even the earliest hunter-gatherers influenced our planet in irreversible ways.  For example, archeologists have discovered several large mammals that lived on this continent 1,000s of years ago that are now extinct.  What happened to these amazing beasts?  They may have died off as a result of climatic changes (the ice age), but it is also possible that they were hunted to extinction.

Research one of the following extinct large mammals from N. America.  Write a paragraph describing the animal and the evidence of its existence.

We have been studying rocks and the ways that they influence the land. Above is a picture of one the most famous rocks in the world.


Research and respond to one of the following:

  • What famous rock is pictured above and what kind of rock is it?
  • What other famous object is made of rock? What type of rock is it?
