FINDINGS
| Place name on school grounds | Number of Spins in 15 seconds | |
| 1. | Field | 20 |
| 2. | Old J Block site | 15 |
| 3. | Grass hill in the quad | 10 |

WHICH IS THE WINDEST AREA AND WHY?
WHICH IS THE CALMEST AREA AND WHY?
WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL?
CONCLUSION:
so I found out that the field had the highest spins with 80 spins per minute and 13-20kpm the Beaufort force was 3 then the Old J Block with 60 spins per minute that 1 spin per second. The Beaufort force was 6-12 then the Green Hill In The New Kahuis with 40 spins per minutes wind speed was the same as the Old J Block 6-12 then last The Court Gate with 12 spins per minute wind speed.
