Fall Green Down Study |
|
Hello GLOBE Teachers and Students!
The GLOBE Program is conducting an interesting study in the Fall and we urge you all to join in. The study is called Green Down. The Gallaudet GLOBE Partners will also be interested in your data, and will help deaf and hard of hearing students share their results. Check back here at this web page frequently and learn what other students are doing!
What
is Phenology? What is Green Down?
Green
Down is an example of a phenological cycle.
The timing of leaves falling in the Fall is influenced by temperature and/or
moisture. Its detection can be used to examine regional and
global vegetation patterns, interannual variation, and vegetation responses
to climate change. Students will observe Fall leaf color as it occurs
on selected trees.
How to
do the Green Down Study
We encourage
you to follow the Phenology protocol exactly as GLOBE describes it.
Then see below for
how
we will share your results with other participating deaf and hard of hearing
students.
For a description of the GLOBE Green
Down Protocol click here (pdf format). See page 15.
Here is a pdf file with GLOBE
worksheets for doing the study.
For Site Definition, Page 2. Green Down data sheet, see page 5.
You'll need a GLOBE Plant Color Guide: about $7.00.

Ideas for Sharing your Results
Let Us Know
If you
plan to do the Green Down Phenology
Study send email and
tell us. We will list your school (below) with other participating
schools. If you send us pictures of your trees or your students working
we'll post them here too.
Student Report Writing
Students
should write about their Green Down
observations. Here is an example of an online report
produced as a Language Experience Activity at MSSD during Spring 2002.
If your students write reports send
them to us - we will publish them here from this web site.
Videoconference suggestions
Does your school have videoconferencing
capability? Would you like to videoconference to talk about
Green
Down in your area? Contact a school from a different
part of the country and compare! Send email to Mary
Ellsworth at MSSD for suggestions.
If you arrange a videoconference
with another class about Green Down,
let Mary know you're doing that. Take pictures and we'll share them
here on this page!
