Crocs, then and now: Students investigate the geographical distributions, habitats, and other features of modern crocodilians and the so-called SuperCroc (Sarcosuchus imperator). Students will consider the things they can learn about one species by studying the other. (Learn more); Format: lesson plan (grade 8–12 Science); Provider: National Geographic

Frosty the Snowman meets his demise: An analogy to carbon dating: In this Science NetLinks lesson, students will be asked to consider the case of when Frosty the Snowman met began to melt. The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.

Layers of the Grand Canyon: In this Xpeditions lesson, after learning the basics of how the Grand Canyon was formed, students investigate the canyon's layers and learn about the geologic time periods when they were deposited.

Paleo-what? The life and work of Emerging Explorer Zeray Alemseged: In this Xpeditions lesson, students explore the field of paleoanthropology. They consider how National Geographic Emerging Explorer Dr. Zeray Alemseged chose paleoanthropology as his career as they learn more about the multifaceted field itself.

Physical characteristics of places: The fossil record: This lesson asks students to consider how the movement of the Earth's tectonic plates alters the physical characteristics of places over geologic time. They'll investigate how climate has changed in specific world regions since the time of the dinosaurs and will write paragraphs explaining their findings.

Radioactive decay: A sweet simulation of half-life: This Science NetLinks lesson is the second lesson in a three-lesson series about isotopes, radioactive decay, and the nucleus. Students are asked to simulate radioactive decay by pouring small candies and counting which candies fall with their manufacturer's mark down or up. Predicting and successively counting the number of remaining “mark-side up” candies should help students understand about the rates of decay.
