Investigating the relationship between local weather conditions and plant phenology Storyline: Joy Hamilton, a high school teacher in the village of Shageluk, in western Alaska (62.63°N and 159.58°W), set up a GLOBE weather station near the Innoko River School in the fall of 1999. The following spring, she and her students began a plant phenology program in which they observed the green-up, budburst and green-down of the local trees. Her classes have been making these observations and measurements every year since. As a science teacher, Joy is aware that there has been more anomalous weather in Alaska over the last decade. She has decided that she and her students should investigate whether or not this less predictable weather has had any local consequences. They decide to examine their GLOBE budburst data to determine if local weather conditions (average daily air temperature, precipitation, etc.) have had a significant impact on the timing of this important plant phenology milestone. Analysis Tool and Datasets: The tool of choice for this activity is Excel (a commercial software package) GLOBE budburst data will be downloaded from the GLOBE web site (http://www.globe.gov http://viz.globe.gov/viz-bin/access.cgi) Weather data will be downloaded from the Weather Underground web site (http://www.wunderground.com/) Demonstration long-term data set (phenology, mean daily air temp, daily precipitation and snow on ground) for the Fairbanks AK area will be provided (this may be housed on the GI or IARC server at UAF)

Completed activity In the first part of the activity, students will retrieve the Budburst data from Shageluk, AK, from the GLOBE web site. Then they will import into Excel and edit and graph it .
