ScienceFLEX Earth’s Changing Surface

Grades 3 - 5

Landforms around the world provide a dramatic backdrop for examining how weathering, erosion, and deposition shape Earth's surface features. Guide students through an exciting exploration of forces shaping Earth's surface wrapped up in 5E lesson plans where students investigate through active learning, then apply their new knowledge to find out how we can limit the effect of such processes on people and the environment.

Leveled Readers are available in four Lexile Measures, distinguished by a color key on the back of each reader.
