2  MYP Unit Question: How does land change?  Area of Interaction: Environment  Learner Profile: Caring and Principled  Standard: Investigate the scientific view of how the Earth’s surface is formed.

3  Bell Ringer: Study Jams Video  Learning Target: Today I’m learning how gravity and water cause erosion because I want to know if I can prevent it.  Work Session: Notes – Erosion by Gravity  Closing:
