SCIENCE CONCEPT:
- Environmental conditions, temperature, density, and pressure,
are continually changing.
STUDENT OBJECTIVE:
- The student will observe through a demonstration that wind
and the direction of the wind will greatly effect rain (a
beach ball will be used for the rain.)
OVERVIEW:
- In this activity, the student will use an electric fan as a
source of moving air and a beach ball to represent rain.
The fan will point upward and turned on. A beach ball is
placed over the moving air and released. The beach ball is
suspended in the air and when the air is decreased, the beach
ball then falls toward the fan or Earth.
