It's Raining - Assessment

WHY?

The air above the fan is moving very quickly and has enough force to lift the ball. The force of gravity prevents the ball from rising very high. The force of air moving upward at this speed tears apart large raindrops that are heavy enough to fall, and the tiny droplets remain suspended in the air.

ASSESSMENT: Can the student communicate what they observed?
