SCOPE AND CONTINUITY OF SCIENCE


12. The aching of bones and the ring around the moon may
 accompany weather changes but are not reliable means of
 predicting changes in weather.

Concepts appropriate to grades VI, VII, and VIII.
1. Climate is considered weather conditions over a long period
 of time.
 2. Most hurricanes which strike the state from the southeast,
 move in a curve, and pass from the state in a northeast
 direction.
 3. Wind is due to unequal atmospheric pressures.
 4. Factors, such as altitude and moisture, contribute to at-
 mospheric pressure.
 5. A barometer is used to measure atmospheric pressure.
 6. The speed of sound is affected by weather conditions.
 7. Weather conditions affect the transmission of sunlight.
 8. Changes in weather are dependent upon unequal heating of
 the air.
 9. Sea breezes are due to unequal heating of the air over land
 and water.
10. Condensation under varying conditions cause dew, frost,
 fog, clouds, rain, snow, sleet, and hail.
11. The weather map may be used for predicting weather
 changes.
12. Storm predictions can sometimes be made by the layman
 if he understands high and low pressure areas.
