INSTAAR STUDENT OPEN HOUSE 2001

|
The entire eighth grade (about 140 students)
from Southern Hills Middle School in Boulder, CO participated in
the third annual INSTAAR Open House on Friday, May 18th. Mrs. Briggs,
their science teacher, lead the Southern Hills students, who had
divided themselves into small groups of fifteen. Each small group
was lead by a INSTAAR scientist through the morning's open house,
which took place at or near INSTAAR
and NSIDC (National Snow and Ice
Data Center). Exercises included:

Many of the students had been to the previous Open
House (Fall 1999) as seventh graders and were enthusiastic about
the new activities, such as the sampling the creek. The purpose
of the repeat visit to INSTAAR is to reinforce their impressions
of the diverse aspects of Earth science, the use of sophisticated
instrumentation and modeling in Earth science, and the relevance
of Earth science to important global and local issues.

The INSTAAR Open House committee members were Diane
McKnight, Bill Manley, Bruce Vaughn, Ryan Vachon and Vicky Nelson.
Ryan Vachon organized the INSTAAR graduate students and staff who
led the small student groups. Some of those leaders are pictured
at left in white t-shirts. Main organizer Diane McKnight is wearing
a green shirt.
The Open House was a big success thanks to the many
8th graders, faculty, staff, grad students, and researchers who
participated!

The students learned about the relationship between
streamflow, water quality, and the insects that live in the stream,
and were shown how to measure streamflow, and collect samples of
water and insects by graduate students from the limnology lab at
INSTAAR.

By visiting a few of the many labs at INSTAAR and
NSIDC (National Snow and Ice Data
Center) students learned how materials such as bones and soils are
radiocarbon (14C) dated, how climate controls the extent of glaciers
and sea ice, and how climate is recorded in ice cores.
