Understanding GLOBE Student Data

Understanding GLOBE Student Data
Gary Randolph Regional Director Europe and the

GLOBE students study the environment of our planet
3
Students begin by studying their own local
environment looking at the air, the land, the
soil, and the water.
4
This is where many teachers and students
STOP
5
But
6
the fun is just beginning!
Looking at data can be fun and a little
addicting!
7
Graphs
Maps
Raw Data
Students can visualize data in several different
ways.
8
Data can be displayed as individual data in a map
(for instance, this map displays the maximum air
temperature in Europe on March 3, 2000).
9
The data can be placed on an x,y scatter plot,
showing the relationship between air temperature
and latitude.
10
Data can also be displayed as contours (for
instance, this map displays the maximum air
temperature in Eastern U.S. on March 28,
1999). Scientists often ask, Are the data
reasonable?
11
Look at the colors near Chicago and New York
City. Where do these colors lie on the
temperature scale? Are these temperatures
reasonable in late March?
12
When we display the data in an x,y plot we can
see that there may be a couple of errors. 55 C
at 40 Latitude and 30 C at 42 Latitude dont
seem like reasonable values for late March. What
might have happened to cause these errors?

Student data can be compared to Environmental
Models
14
Data can also be displayed in graphs. This is
mean air temperature for a school in
Pennsylvania, USA.
15
Math extension how is mean temperature
calculated?
16
Data from multiple schools can be displayed in a
graph. This is the mean air temperature for the
school in the U.S. combined with the mean air
temperature for a school in Australia. Can you
see how air temperature, and perhaps
seasons, differ between Northern and Southern
hemispheres?
17
Data from up to six schools can be displayed in a
graph. This is the mean air temperature for the
school in the U.S. and the school in Australia
combined with the mean air temperature for a
school in Benin, West Africa. Now, air
temperature and seasonal fluctuations can be
seen for Northern and Southern hemispheres as
well as near Equatorial.
18
Data sets are created on demand. This allows for
a closer look at a particular year or years.
19
Data can be displayed in stacked graphs for
easier observation.
20
Graphs of data can also be used as a tool to
explain relationships in the natural world.
What environmental data might be represented here?
21
Whatever data are displayed, they seem to be
inversely proportional.
22
What if you knew that the red line represented
Surface Water (SW) Temperature?
23
Here is a Clue
Henry's Law
The value of the Henry's law constant is found to
be temperature dependent. The value generally
increases with increasing temperature. As a
consequence, the solubility of gases generally
decreases with increasing temperature. The
decrease in solubility of gases with increasing
temperature is an example of the operation of
Le Chateliers principle.
24
Henrys Law states that as temperature
increases the solubility of a gas decreases.
Dissolved Oxygen fits both Henrys law and the
pattern of the graph.
25
Student data can display what Henrys Law states.
Notice that as the red line (Water Temperature)
increases the green line (Dissolved Oxygen)
decreases.
26
Data from other parts of the world show the same
relationship.
27
What is the relationship between precipitation
and soil moisture?
28
Soil moisture values drop during dry periods and
rise again with the introduction of rainfall.
29
Students can then look beyond GLOBE
measurements and begin asking questions about
their local environment.

Cases of Malaria
Temperature
Precipitation
Students at this school in Benin graphed cases of
malaria with temperature and precipitation.

Helsinki, Finland June 30 - July 4, 1998
Fayetteville, Arkansas, USA June 25 - 28, 2000
Sibenik, Croatia June 29 - July 4, 2003
Students can present their GLOBE research at
Student Research Conferences
32
GLOBE Student Learning Expedition Croatia 2003
June 28 July 5 in ibenik, Croatia

• Participants included nearly
• 400 students and teachers from 24 countries.
• Each country presented their winning research
  results.
• Two field campaigns included (inland park and
  island).
• Field campaign data was presented by students and
  scientists.
• Cultural and leadership values extended.

Participating countries Argentina, Bahrain,
Cameroon, Canada, Croatia, Cyprus, Czech
Republic, Egypt, Estonia, Finland, Germany,
Hungary, Iceland, Japan, Lebanon, Norway, Poland,
Qatar, Spain, Switzerland, Tanzania, Thailand, UK
and USA.
33
Students can publish their research on the GLOBE
Website
34
GLOBE has trained over 29,000 GLOBE
Teachers representing more than 16,000 GLOBE
Schools worldwide. Students have entered over 13
million Measurements to date.
35
GLOBE data is used by student scientists around
the world to help them us learn more about their
environment.
