The Standard

E.1.9B: Students will demonstrate an understanding of models (drawings or maps) to describe how water and land are distributed on Earth.

With teacher guidance, plan and conduct a structured investigation to determine how the movement of water can change the shape of the land on Earth.

Teacher's field guide

What Students Need to Do: With a teacher, students choose where to pour water on a sloped tray of sand. They sketch the sand before and after, then describe what the moving water changed.
What Mastery Looks Like: A student points to a groove the water made and a pile of sand at the bottom. They explain that water carried sand from one place to another.
Common Misconceptions: Students may think water only makes soil wet, without moving it. They may think a groove formed because the sand sank rather than being carried away.
How to Assess It: Draw a sand mound before and after water makes a groove and a pile at the bottom. Ask, “What moved the sand, and where did it go?”

Lesson moves

In pairs, sketch a sloped sand tray, pick a pour spot, trickle water from a cup, then sketch any grooves and piles.
Show before-and-after photos of a streambank and ask, “Where did the soil go? What do you see that tells you?”
Give pairs before-and-after sand tray drawings; have them circle where sand washed away and point to where it collected.
Show a photo of a rain-worn sidewalk path; ask students to mark the groove and the dirt piled at its end.
