Canyons in 2nd Grade

This week students investigated the question, "What makes a canyon?"

Students hypothesized that it could be earthquakes, asteroids, tornadoes, or erosion.

Here is an example of  the final product after 4 rainstorms.

Students discovered that erosion wears away at the rock and sand and creates new land forms like canyons, cliffs and landslides.

Here is a video after the final rainstorm for all projects:
