About the author Reen Gibb currently teaches at Brookline High School in Massachusetts, where she has been for 20 years. Her teaching experience includes secondary and middle school biology, secondary school physics, and college and secondary school chemistry. Ms. Gibb also teaches in the Education Department at Wellesley College and works as a consultant for a Boston University Science Foundation grant that focuses on using the computer as a virtual laboratory in the chemistry classroom. Students use longitude and latitude coordinates to trace and estimate the miles on Shackleton's actual and intended polar journeys, describe the altitude changes across the continent, and compare Antarctica to their own state. Students make miniature icebergs, float them in water, expose them to the sun, and compare them to a floating cork stopper.
Students also estimate the amount of drift ice around Antarctica.
