OverviewFor 2 lessons,our group went to the 7 different locations in the school to measure the temperature of the places.There were 2 different ways of measuring the temperature,the first way using our own body to estimate and the second using thermometer.

Process For the process of taking the temperatures,we planned the route to take to

ensure that the shortest amount of time can be taken.(from 1st place of visit to 7th as last place of visit)The areas are:

• A-Top floor of multi-storey car park(mscp)------------>3rd

• B-Garden outside printing centre------------->4th

• C-Open spaces between canteen & block C------------>1st

• D-Terraces------------>5th

• E-Field--------------->6th

• F-Running Track------------>7th

• G-Fountain area outside General office------------>2nd

• Time taken:approximately 15-20 mins

Day 1For the 1st lesson,we used our bodies to estimate how hot or cold a place is,based on a ranking of 1 being hottest and 7 being coolest. Then we used thermometers(visit #1)

We started at 8am and ended at

9am.

Day 2On the second lesson(visit #2), we used thermometers again but this time, we did at from 12.30pm to 1.30pm under the afternoon sun.

Both visits are combined into one slide due to time constraints.

A. MSCP On the 1st lesson, we felt that the multi-storey Car park was the least warm so we rated it as 7. The Car park at noon on the second lesson was full of cars and the surface was concrete, and the car park is directly under the sunlight, yet we rated it 6 as we were standing at the wrong part( under the shade)

B.Garden outside printing areaWe went to the garden behind the general office, and on the

second time we felt that it was warm so we rated it 4. The garden has some trees at some areas, but the spot which we stood on was not covered by any trees, and the sunlight was shining directly on us. The road is made up of concrete. The first time we rated it 4 as it was morning.

The open spaces between the carpark and block C was ranked 3 although it was early in the morning. When we went out a second time around noon, the temperature was higher. Compared to 27.5 degrees on the first day, the second day’s temperature read 30.6 (rank 7), standing in the shelter of block C.

C. Open spaces between canteen and block C

D. TerracesThe terraces on the first visit were cool and sheltered, thus the temperature ranking was 6. The second time saw a major difference. At 32.6 degrees, We ranked it 1 on the heat chart. The terraces is a concrete seating area, and since secondly we took the reading at the base of the terraces, unaffected by shelter, it read hottest on our chart and thermometer.

E. FieldThe field was rated 4 on the first visit. Completely under the brunt of the morning sun, the field still managed a surprising 26.9 degrees celsius, probably due to morning clouds and dew. The second visit bore different results, with rank 3 at 31.0 degrees.

F.Running TrackFirst visit ranked 1 despite cloudy weather due to multitude of people congesting the area, is under the morning sun like the field.

Second visit ranked 2 as it was under the afternoon sun and the sky was cloudless.

G.Fountain area outside general office

First visit rated 2 due to it being under the sun and many people around area, and is a concrete area. Second visit rated 5 as temperature taken near source of water.

DiscrepanciesSecond visit marred by mistakes as temperature readings in B, E and F all read 31.0 degrees. Thus their second rankings are actually the same, but numbered ranking given randomly.

Likewise in A and G, both temperatures read 30.7 degrees.

HypothesisGiven hypothesis: Concrete areas are generally hotter than non-concrete areas.

Results proved that: concrete areas generally hotter than non-concrete areas, with reasons to account for the cold concrete areas.

In A and CStanding under the shade caused the temperature reading to be affected. Unlike what we did in E on the second time, where we stood directly under the sun, that time we did the reading at the wrong place, causing temperature and ranking to be messed up.

Conclusions>Concrete areas are generally hotter than non-concrete areas, like grass and water.

>Time of day affects temperature of areas

>When doing fieldwork, ensure that all tests are done equally, such as not standing in shade when we ought not to.

Finally...Thank You for your listening ears.
