Stream Table

Use an interactive stream model: change the slope or the water, and watch what moves.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 10

Welcome to Earth Watchers! Rivers change land too slowly to watch, so scientists build models. A stream table is a tilted tray of sand with water running through it.
Try it! Change the slope and the water, and watch the number. These are sample numbers, like a real tray might give.
To test fairly, change one thing at a time. That one thing is called the variable.
Try it with a grown-up: prop up a tray of sand outdoors, pour water from a cup, then make it steeper and pour again.
