Title: Physical Characteristics of Places: The Fossil Record
This Xpeditions lesson asks students to consider how the movement of the Earth's tectonic plates alters the physical characteristics of places over geologic time. They investigate how climate has changed in specific world regions since the time of the dinosaurs and write paragraphs explaining their findings.
Standard(s): [S1] GEL (9-12) 10: Explain the mechanism of plate tectonics.
Title: 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. They conclude by writing newspaper articles from the perspective of scientists researching the canyon's layers.
Standard(s): [S1] GEL (9-12) 6: Explain the concept of geological time within the framework of the geologic time scale.
Title: Fossils and Geologic Time
This Science NetLinks lesson helps students understand the development of the geologic time scale. It also introduces students to the major time periods in Earth's history, as well as to the role fossils play in helping us understand this history.
Standard(s): [S1] GEL (9-12) 7: Describe processes of rock formation.
