Hypothesis
As the wind speed increases, the temperature drops
Items used
An all-in-one instrument that can measure things like temperature, wind speed, humidity and air pressure.
Within that, we used: Anemometer
To measure the wind speed Thermometer
To measure the temperature
Procedure Summary
We would be going to strategic locations across the Hwa Chong Campus on the 29th January and the 4th February from around 11am to 12am to find out how the wind speed can affect the temperature
Locations
Top floor of Multi-storey Car park Open air fire hydrant
Garden outside the printing centre At the tree stump
Open space between the canteen and Block C
At the centre of the semicircle
Terraces On the ninth step
Field At the flag pole
Running Track At the starting point
Fountain area outside General Office At the corner of the fountain nearest to
LT3
Procedure Get to the specific location
Make sure that this is the exact same location for both days
Procedure (Wind)
Use the anemometer to measure the wind speed
Anemometer must be in front of the user and the user must face the wind
Anemometer should be slightly higher than the user, to make sure that no wind is obstructed
Procedure (Temperature)
Use the thermometer to measure the surrounding temperature
Let the reading stabilize before taking it Make sure the height at which the
temperature is taken remains constant, because heat from the ground might interfere with the results.

Evaluation
Is the hypothesis true? Yes, since we can see a trend that as the
wind speed increases, the temperature decreases
Unusual Data? There are lots of unusual readings we
had, but these are probably caused by our lack of much precaution and of proper equipment
The unusual reading might have also been caused by the varying weather conditions such as presence of cloud cover
Problems Faced
Difficult to get a constant reading because of fluctuating wind speeds and temperatures due to varying intensity of sunlight
The instruments used to collect the data was not very reliable and restarted often
Learning Points
The higher the wind speed, the lower the temperature of an area
The intensity of sunlight and proximity to nearby buildings also affects the temperature
The temperature nearer the ground is hotter because there is more heat radiating form the ground
Questions Does humidity affect the temperature of
an area?
Is wind nearer the ground stronger or wind higher in the air?
