A Model Station at the Kitchen Table

During a family science afternoon, Anika set up a model station at the kitchen table. She wanted to compare ways to keep flowing water from changing the shape of a small hill. An adult covered the table and helped her use soil, dry leaves, and smooth rocks. They kept the materials away from food and washed their hands afterward.

They shaped three matching soil hills in dishes. Each hill had the same amount of soil and the same slope. One hill was bare. One had a leaf cover laid flat over the soil. One had a row of rocks across the slope, with spaces between the rocks.

The adult poured half a cup of cool water onto the top of each hill over fifteen seconds. Water drained into a white bowl below each dish. Anika looked for new grooves in the hills and soil in the bowls. She also watched whether the leaves and rocks stayed in place.

Bare hill: A long, deep groove formed. A large pile of soil collected in the bowl.
