Chilling with Integers: Unearthing Climate Secrets

As a budding climatologist in the university’s Earth Science department, you’ve been tasked with analyzing temperature data for several regions. This data is crucial for understanding climate patterns and making predictions. The temperatures are often in the negatives due to the regions’ sub-zero climates in winter. For this task, you’ll be working with integers to crunch the numbers and draw your conclusions.

 

• Integers: Whole numbers and their opposites. The set of integers includes zero, positive natural numbers (or counting numbers), and their negatives.
• Number Line: A line with equal intervals or segments that show numbers in order. It helps visualize the order of integers and their absolute values.
• Absolute Value: The distance of an integer from zero on a number line. Absolute value is never negative.

You start your day analyzing data from Barrow, Alaska.

Now that you’ve checked Alaska, you move to study data from Yellowknife, Canada.

After Canada, your research takes you to Russia.
