We started off the activity with "human thermometer" for the five different sites.
Rating based on our senses without the instruments
Measuring of humidity is tedious with the sling psychrometer as we have to swing the instrument with 2 swings per sec which is like 120 round per min!
Sling Psychrometer - to measure humidity

Using the weather tracker, we compared the readings and tested our hypothesis on how the temperature was affected by the amount of shade and concrete surface area. Some areas are more exposed and floored with cement such as the parade square which resulted in the highest temperature recorded. In the areas which are more shaded and with soil such as the garden recorded the lowest temperatures.

I prefer to use this weather tracker which shows the humidity, temperature and wind speed - less tedious.
