Students should use the resource on the North Pole student esheet to help them answer these questions. This sheet provides you with some answers to the questions.
Why is the North Pole hard to study in winter?
It’s cold and dark and hard to get to. And pictures taken in the dark don’t tell as much as pictures taken in sunlight.
What happens to the temperature in the Arctic, or North Pole, during the summer?
The air gets warmer and the ice melts creating ponds and potholes in the ice.
Name two kinds of transportation that scientists used in the past to collect Arctic temperature data in the summer. What is the problem with these?
Ice-breaking ships and helicopters were two kinds of transportation they used. They are really expensive to operate.
To collect data more easily, what technology do scientists now use to track summertime temperatures in the Arctic, or North pole?
They use Web cams. These are portable cameras that track changes continuously and send pictures and other data to computers to be analyzed.
Before Web-cam use, how many times had scientists collected good data on summertime Arctic warming?
They had collected good data four times before Web-cam use.
Does four sessions to take pictures by boat or helicopter seem like very many times to you?
Students should frame the response in terms of “more is better” in the data world.
Why is it better to collect more data than just a little bit?
Collecting more data increases the likelihood that the findings are true. Scientists call a lot of data “robust data.” They accept findings as true scientifically only when the data are robust—or in other words, when there are a lot of data collected under the same controlled conditions.
