Our Amazing Earth
A Classrooms Unleashed Program
for Fourth Grade Students
This unit focuses on patterns of change at the earth’s surface. Students become geologists and explore how physical weathering and factors affecting the rate of erosion change the earth’s crust over time, including the influence of human impact. In addition to a field study at a local natural area, we provide in-classroom lessons, led by Sierra Nevada Journeys instructors.
All of our lessons are backward designed from Next Generation Science Standards and Common Core for fourth grade. In addition to the Sierra Nevada Journeys-led lessons, classroom teachers will be provided with 3-4 easy-to-use learning experiences to reinforce concepts and vocabulary.
PROGRAM OVERVIEW
Classroom LESSON: WEATHERING and EROSION
Students use hands-on simulations to discover the concept of weathering and investigate the causes and effects this natural process has on rocks.
They will also explore how different factors affect the rate of erosion. Students then use their understanding of how sediment moves to collaboratively build a model of a landscape with the goal of changing the rate of erosion using materials from the schoolyard.
Outdoors at a Local Nature Area: GEOLOGISTS IN THE FIELD
Students use their observation skills to explore the outdoors and document evidence of weathering and erosion as a real natural process in the field.
