What do I expect to be the primary benefits to my peers, my students, my colleagues, my friends, and myself?
The entire experience was unbelievable. The research, although tedious at times, proved to be fun. I am going to encourage my fellow teachers to apply for similar expeditions. My excitement about sharing what I have learned with my students hopefully will teach them that science is more than experiments and textbooks. Science surrounds us everyday. A major benefit for my colleagues is the opportunity to share ideas and expertise with each other. I hope we always remember the thrill of riding the Zodiak onto and standing on the ice floe in the Hudson Bay!! What an experience!
Has the project in any way changed my approach to teaching or learning?
One eye opener I had was how difficult it was to follow a lecture if I was unfamiliar with the vocabulary. As an educated adult I sometimes forget that my students do not always understand all of the terms pertinent to the topic under study. Although our presenter thoroughly enjoys his research, his enthusiasm did not always transfer to me as I listened to his evening lectures. Granted, I was tired by 7:30pm after spending 7 hours in the field, but my interest in the topic might have been sustained if I was more familiar with pingos. polygonal peat plateuas, and palsas.
During the course of the study I did learn that a pingo is a mound of gravel or earth occuring inn Arctic regions as a result of pressure from water ttrapped between newly frozen ice and the permafrost beneath it. A palsa is in an area of permafrost, a peat mound, several metres in height, and up to 100 m in diameter, which obtrudes because it is better drained and thus more subject to frost heaving than wetter areas.
In retrospect, I know I need to stress the vocabulary of scientific terms more than I have in the past. My challenge will be to keep my students interested in science at the same time.

What has the experience taught me about scientific research and conservation?
Scientific research does not have to be conducted in a well equipped lab. I need to expose my students to more investigations outdoors. If I truly desire to instill a sense of responsibility for the environment within them, I need to provide as much exposure to the natural world as possible. These experiences can be as close as the school yard. I am fortunate that our school sits on at least 10 acres and has open and wooded areas.

What skills did I learn?
Before the trip I was not comfortable blogging and utilizing internet networking but my team members enthusiastically encouraged all of us to engage in these activities. I now believe that I will try to incorporate a blog into my communication options with my students and their families. I also learned that I must stress with my students the importance of being able to work within a group, large and small. It is vital that they are able to listen to each other's opinions and ideas.
How does the research in Churchill and what I learned relate to me and my local community?
Like many others, I often forget that my actions and decisions have global consequences. My choice of vehicle to drive, the cleaners I use, even the type of lightbulbs I burn all effect the global climate. Maybe not individually, but aggregately with the rest of the world population. It is my hope to discover if an environmental ethic can be instilled in adolescents even if they do not feel a personal connection with nature.
How will I bring the experience home?
Last year my students and I learned science through an interactive unit about Antarctica. This year I plan on integrating my experiences in Oslo, Norway and in Churchill, Manitoba into a unit about both poles. The majority of our curriculum can be addressed through polar science. Concepts of erosion, glaciation, weather, climate, genetics, classification, and matter all connect to the Arctic and to Antarctica.
Teachers at the conference in Norway and those on the Churchill expedition enlightened me with abundant ideas for use with my students. Some of the Earthwatch educators and I plan to replicate the Dr. Kershaw's study with their middle school students in their school environment. My students and I will also monitor seasonal sightings of migratory birds in our local area in order to track indications of climate change.
What were the challenges?
Before the trip my biggest concern was the bugs. My brother lent me a hooded long sleeved shirt made of mosquito netting. What a life saver! I never ventured outside without it. I took it off maybe once on a windy day while out in the field otherwise it was attached to me. As you can see in the picture all of us conquered the bug dilemma!

What were the highlights?
Without a doubt--the people!
The eleven of us were divided into teams of three to gather our data. My team was Kevin, Sheryl, and me. Although we "discussed" many issues in the field, I'm thankful for the opportunity to work with them. Sheryl insisted on accurate and complete data while Kevin entertained us with his puppet shows! Thanks to Kevin's insistence we all took a late night dip in the Hudson Bay!

What images stand out in my mind?
1. The age of the trees astounded me. The trees in the above picture are between 100-150 years old.
2. The flat landscape surprised me. Pete Kershaw showed us a contour map of the area and it had one contour line on it. I wonder how many kilometers we could see as we looked at the horizon from the Churchill Northerne Studies Center. The middle picture is the view looking north from CNSC with the Hudson Bay on the horizon.
3. Although we were in Churchill during the summer solstice and had 17 or more hours of daylight each day, the nights never became dark. The sun dipped below the horizon for a brief time and then crept back up. Each time was more beautiful and colorful than the last. I do not believe any team member will ever forget the beautiful night skies.
