Trees and Soil

In this area that is often referred to as high marsh, you may also see trees. If you wish to measure the height of a tree, you can do this using math! [teacher note: go online for a series of materials on how to measure land cover. There are several different methods suggested for obtaining tree heights; included are educational standards as well. You can also use the Earth as a system activities to look at seasonal changes: green up and green down will give some hints of how to do this.] Can you think of how you might do this? Take a look at the trees. Do you see any buds? Dead leaves? How would you estimate the numbers of buds or dead leaves without actually counting them?

Soils in these areas can be very interesting. [teacher note: the NASA soil science education page has many activities and resources that are very accessible for different age groups.]
