This classroom activity helps students understand how the angle of the Sun affects temperatures around the globe. After experimenting with a heat lamp and thermometers at differing angles, students apply what they learned to explain temperature variations on Earth. The printable six-page handout includes a series of inquiry-based questions to get students thinking about what they already know about temperature patterns, detailed experiment directions and a worksheet that helps students use the experiment results to gain a deeper understanding of seasonal temperature changes and why Antarctica is always so cold.

This multimedia resource, part of the NC Science Now series, describes how Dr. Roland Keys, Director of the Biodiversity and Earth Observation Lab at the NC Museum of Natural Science, is using remote controlled, hidden cameras, telemetry and GPS to record animal behavior and movement and to study whether human activity is affecting animal populations in a specific area. Components of this resource include a video, a related blog article, and an interview with Dr. Keys. Links to these components are provided on the page under the heading "UNC-TV Media."
