Objective

Our Earth is constantly reshaped by forces of erosion, as wind, water, and ice wear away the Earth’s landscape. Creating a stop-motion video on erosion can help students better understand the scientific method and the powerful effects of erosion.

Overview

Topic	Earth science
Target age	12 to 13 years old
Ideal group size	2 or 3 students
Time to complete	2 to 3 class periods

Activity

1. Students should form groups of two to three to research wind, water, or ice erosion.
2. The groups must design an experiment that demonstrates the effects of one type of erosion, then create a stop-motion video of their experiment.
3. Each movie should follow the steps of the scientific method: Ask a question, research the question, create a hypothesis, test the hypothesis, analyze the data, share the result.
4. After students share their experiments, the class can compare the effects for each type of erosion and see which effects are most or least damaging.
