Climate Change Data Analysis: Graphing Polar Bears & Arctic Sea Ice (NGSS HS Biology)

Description

This is the activity that started Beyond the Brains’ reputation for data work — and it holds the store’s five-star TPT review, from an educator who praised exactly what it’s built to do: get students analyzing real-world data instead of reading about it. Students construct graphs of Arctic sea ice and polar bear population data, identify the trends, and connect habitat loss to population impacts with the evidence on the page in front of them.

What’s inside

Per the current listing, students construct graphs of Arctic sea ice data and polar bear population data, identify trends, and connect habitat loss to population impacts. The TPT audit records this resource at 5 pages. The exact breakdown of those pages (data tables, graphing space, question sequence, answer key) is not enumerated in the current listing and should be confirmed before this section itemizes it.

How it runs in class

Run it as the data core of an Arctic or climate sequence: students build the graphs themselves, which means the trend — shrinking ice, stressed populations — is a finding they own rather than a fact they were handed. It works as a standalone analysis lesson, as the examine-the-evidence engine inside the Arctic 5E line, or paired with the free Polar Bear Observation activity as a phenomenon-first opener. Because the two data sets sit side by side, the habitat-population connection has to be reasoned, not assumed, and class discussion afterward has real numbers to argue about.

Standards alignment

NGSS: HS-LS2-6, HS-LS2-8. Grades 6–12 · Biology, Environment, Marine Science.

It also anchors the Arctic line’s skill progression: the graphing and trend-reading students practice here are the same moves the sea ice data in the units demand, and the observation freebie that precedes it means students meet the data having already watched the animal it describes.
