Use the following websites to find
information and ideas that will help you investigate "Our
Changing Earth." As more resources are created, they'll be
added to this list, so visit often.
Brownfields are "abandoned, idled, or under-used
industrial and commercial facilities where expansion or
redevelopment is complicated by real or perceived
environmental contamination." Use these resources to learn
how you can help to reclaim brownfields.
Water has the ability to change our earth. Too much or
too little water can be deadly and destructive. The quality
of water also effects survival. These resources will help
you understand the power of water.
Do you live near a river or stream? Chances are you do.
Rivers cut through much of the North American continent.
These resources offer great ideas for how you can use your
local river as a classroom for investigating science.
Wetlands present an interesting opportunity for studying
earth science. You can see the interaction of water and soil
most clearly. These websites introduce you to the ecosystem
of a wetland.
Open the door and step outside into the nearest
habitat—your schoolyard. Use these resources to plan an
investigation of the natural world that's closest to your classroom.
Finally, to see the really big picture, consider
earth as seen from space. Imagine the changes you'd see if
you could watch the world spin from outer space. Over time,
the view would be awesome.
