----  ----
At the 2002 Spring meeting of the American Geophysical Union  (AGU), 
being held at the Washington Convention Center
there will be a special, invitation-only poster session for high school-aged students in the Earth and space sciences

MSSD Students have received an invitation to present.
Thursday, May 30, 2002
Tentative Schedule for the day.

Several science programs in the Washington, D.C. and Richmond, VA region allow promising high school students to conduct research on topics related to the Earth and space sciences. This session will highlight the recent research results of these student projects associated with, among others, the Richmond Area Higher Education Consortium (AHEC), Earth System Science classes at the Model Secondary School for the Deaf, and Carnegie Institution CASE programs.

Students in Senior Team Science classes are preparing two presentations:

Spring Budburst Study          Spring Tree Leaf Reflectance Study
 

Wish us luck!

Session:     1818 ED05  Looking to Tomorrow: Research Projects of High School-Aged Geoscientists

Abstract:    Problem:  Students at the Model Secondary School for the Deaf are observing budburst on two tree species near the school GLOBE (Global Learning and Observations to Benefit the Environment) Atmosphere Study Site.  Understanding that budburst is an example of a phenological cycle, the students investigated the timing of budburst and how it is influenced by temperature or moisture. Students are observing when budburst occurs on selected native trees which are not watered or fertilized.

Hypothesis:  Since budburst can be used to examine regional and global vegetation patterns, the students will compare their data with two other schools, one in Indiana and one in California.  The students hypothesized that different trees will have budburst all at the same time, if they are all in the same environment (temperatures and precipitation).

Procedure:  Students are using the degree summation and estimated evapotranspiration techniques correlated with bud burst observation logs kept during the spring of 2002.  (GLOBE Budburst Protocol).

Session:        1826 ED05  Looking to Tomorrow: Research Projects of High School-Aged Geoscientists

Abstract:      Problem:   Students at the Model Secondary School for the Deaf are investigating if there is any variation in leaf reflectance spectra that correlates with environmental factors. Past student investigations have indicated differences in the reflectance spectra of fresh, aged and dead leaves (MSSD student ESS investigations 2000 and 2001). Would there be a change in leaf reflectance spectra in response to temperature or moisture variations?  We became interested in this question through questions about how much could be determined from satellite measurements about the relative health of forest vegetation.

Hypothesis:   We hypothesized that the leaves may respond to precipitation differences (or drought) but probably will not respond spectrally to the temperature range normally encountered during the spring time in Washington, D.C..

Procedure: The ALTA spectrometer will be used to detect the reflectance spectra of living tree/bush leaves at regular intervals during the spring.  Daily temperature and precipitation data will be collected at the school GLOBE weather station.
