These are professionally-written, complete lessons that are keyed to objectives. These lessons all have some sort of tie-in to Agriculture and are generally for middle-school through high school levels. There are currently about a dozen complete lessons, but check back often as they are being re-written and new ones will be added in the future. http://noble.org/noble-academy/
Very nice maps of North America by region or by states, in a variety of different levels of detail, are available from http://www.epa.gov/wed/pages/ecoregions.htm
If you ask nicely you can sometimes get a large classroom copy mailed to you.
One example of how to use this is to post them side-by-side with a geology map of the same area, or a precipitation map and have the students looks for similarities and patterns in the distribution of vegetation types and the surface geology. They can also look for patterns in the distribution of vegetation types and the amount of precipitation, or of any other weather characteristic you might be able to generate maps of. Shown is Oklahoma but these are available for most states and regions.
If you do any environmental work with kids you will eventually be drawn to the water’s edge – or get deeper into it! All of us who do this need to know the basic aquatic plants. This site will help you in two ways.
First, it has the easiest key you will ever find. You use pictures, photographs and short descriptions, not the detailed descriptions in Latin that we had to learn for Waterfall’s book back in the day. Granted, these keys might not take you down to the most specific level but they can give you an answer in less than a minute to “what plant is that?”. This is one reason to (carefully!) take that laptop into the field.
Second, it provides great photographs to many of the plants, but not all. Did I mention that this is a work in progress?
Third, there are range maps for most of these plants. I know, I said there were two reasons so think of the range maps as a bonus.

There are several maps of where in the state the vegetation types are, or historically were. The classic study is the map of 15 different kinds of vegetation. A smaller copy appears above, and a link to the image is below. Remember – when it comes to images, link, don’t lift! http://www.okatlas.org/okatlas/biotic/vegetation/duckfletcher.htm
A more simplified (12 vegetation types) but more clear map, in pdf format is at http://www.forestry.ok.gov/Websites/forestry/Images/Ecoregions.pdf
There are other maps on this blog – geology, etc. Just search to see what you find that you can use in your classroom!
