A Plan for the Ground Beside the Slide

Rain had made little channels in the sandy ground beside a playground slide. On dry days, wind carried sand onto the path. The school wanted to keep more sand in place.

The class watched an adult test small models outdoors. Each tray started with the same amount of sand and the same slope. For the water test, the adult poured one cup of water onto the top of each slope over ten seconds. The trays had bare sand, a pebble cover, or a low wood barrier across the slope.

For the wind test, fresh trays had bare sand, a pebble cover, or a low fence facing the wind. The adult used a hand fan at the same distance for twenty gentle strokes each time.

A larger tray caught sand that left each model. The class let wet sand dry in the air. They measured the sand with the same small scoop. The graphs show how many level scoops moved out of each model.
