2. Overview On the 24 th of January, at 11 45 am… Our group of 5, led by Andrew left class to begin our journey around the campus. We were going to 7 different locations around the school to measure the temperature, wind speed and relative humidity. We had no more than 45 minutes to complete this task…

3. Our original rating for temperature HottestCoolest 1 2 3 4 5 6 7 CarparkTerracesTrackFieldGarden Fountain Globe

4. Reasoning - One, the carpark  The carpark was open air  The carpark had a concrete ground, and was surrounded by cars. Both radiated heat.

5. Reasoning - Two, The Terraces  The terraces also had concrete stairs. Concrete radiates heat!  The shape of stairs means a larger surface area of concrete. More concrete, more heat radiated. Trees only sheltered a small part of the terraces.

6. Reasoning - Three, The Track  The track was directly under the sun.  The track was made of a rubbery material, which would have also radiated heat.  There were no trees or shelters near most of the track

7. Reasoning - Four, The field  The field would not have been as hot as the track, even though they were at the exact same place.  The field had grass. Grass does not radiate as much heat as rubber or concrete.

8. Reasoning - Five, the Garden  There is lots of grass and vegetation. Though it is open air, it is fairly well sheltered from the heat of the sun, and relatively windy.

9. Reasoning - Six, the fountain  The fountain is a cool place surrounded by water  We expected it to be the most humid, but also expected the water in the air to keep the temperature low.

10. Reasoning - Seven, The Globe  The globe is indoors and sheltered.

11. Our Hypothesis Places with concrete ground tend to have a higher temperature than places with non concrete ground.

24. Hypothesis checking!

25. Hypothesis? No, it is NOT true.

26. The track and field had the highest recorded temperature. Both had no concrete within about two meters’ range of them, and hence places with concrete ground do not necessarily have higher temperatures than places with non concrete ground.

27. Hypothesis? The average temperatures of places with non concrete grounds was 30.9 degrees, higher temperatures than places with concrete grounds (30.4 degrees)
