1. Discuss the effects of glaciation in the Mount Logan area. 2. Take responsibility to teach certain information to their peers. 3. Make an organized oral presentation.
Computers with internet access
Copies of 1:50,000 maps of the Mount Logan area
1. Introduce the lesson by reviewing what was learned last class. Give groups five minutes to review and discuss what was learned yesterday. Depending on the make-up of your class, you may be able to use a “jigsaw” arrangement, in which one person from each research group comes together to make a teaching group, and then each member teaches the rest of their group what they have learned. If your class make-up or numbers do not support the jigsaw structure, each group will make a short presentation to the class. Bonus marks for good visuals! You will need about 40 minutes to make all of the presentations.
2. For the last half hour of class, or perhaps next class if you run out of time, return to the Mount Logan website, to the science section, under “Glaciation,” subsection “Glaciation in the Mount Logan Area.” http://www.museevirtuel-virtualmuseum.ca:80/sgc-cms/expositions-exhibitions/logan/en/index.php/md/Science Hand out copies of research sheets (below). Student Research Sheet: Glaciation in the Mount Logan Area
Use the website to research the following questions. Include as much detail as possible in your answers. You will be using this sheet to study for the final quiz.
1. The last major glaciation occurred approximately how long ago?
2. Which ice sheet affected the Southern Yukon?
3. Was all of the Yukon covered in ice? Describe the ice sheets and ice-free areas.
4. What signaled the end of the ice age? Why?
5. What is the name of the current period?
6. What is an “interglacial period”?
7. What is meant by “neoglaciation” and what were its effects? When did it begin?
8. What drove the neoglacial advance in the St. Elias mountains?
9. What was the “Little Ice Age”? When did it begin? When did it end?
10. What has changed in the last 20 to 30 years?
11. Summarize what you have learned about glaciation in the Mount Logan area. Write a good paragraph including all of the information above, written in your own words.
