1.What causes temperature to be different at different places?
2. Where is the hottest place in HYSS?
3. When is the chosen location the coolest?
4. Why are some places hotter than others?
5. How will wind speed affect temperature?]]> 2018-09-01 16:12:23 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087528 Human Thermometer whyluvvu0608 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087636 From this investigation,  we concluded that Site A is the hottest and Site B is the coolest. Site A is an open space so the sun shine over Site A so it will be warmer.  Likewise, for Site C, it is also an open space so the sun shines over Site C so it will be warmer. As for Site B, it is surrounded by buildings and tall plants so it will block the sunlight and will not be as warm as Site A and C.]]> 2018-09-01 16:14:15 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087636 Primary Data whyluvvu0608 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087662 We collected data of Temperature, Relative Humidity & Wind Speed for 3 locations: Quadrangle, Science Garden & School Field at 2 different timing. Attached below is our result and we used the average result of both timing.]]> 2018-09-01 16:14:44 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087662 Summary/Conclusion whyluvvu0608 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087709 We feel that to a large extent the primary data we collected supports our hypothesis of,the lower the temperature,the lower the wind speed.

From the data we gathered, the average lowest temperature is 33.1•c and the average lowest wind speed is 0.9m/s at Site B (Science Garden).This proves that our hypothesis is true.

On the contrary, the secondary data does not support our hypothesis.

We feel that our collected data may not be reliable as from the attached in primary data, our timing for both reading 1 and 2 have a big difference. The different timings may have cause the result to be different. Hence we feel that our collected data may not be reliable.

We feel that we should take note of the time when collecting data as different timings may affect the results.

Therefore, we would like to conclue that Site B(Science Garden)is the best site to build a speaker's corner as the science garden has the lowest temperature at 33.1•c as compared to the other two locations.Students can have a cooler environment and not feel as warm as in the field and the quadrangle.]]> 2018-09-01 16:15:34 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277087709 Annotated Picture (Quadrangle) whyluvvu0608 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277089348 Site A is an open space thus sunlight reflect causing the location to be warmer as compared to Site B which is not an open space.]]> 2018-09-01 16:39:42 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277089348 Annotated Picture (Science Garden) whyluvvu0608 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277089395 2018-09-01 16:40:26 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277089395 Annotated Picture (School Field whyluvvu0608 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277089402 Site C is an open space thus sunlight reflect causing the location to be warmer as compared to Site B which is not an open space.]]> 2018-09-01 16:40:37 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277089402 Gathered Data jiesheng https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277141266 2018-09-02 12:01:53 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277141266 Primary Data: Temperature, Relative Humidity & Wind Speed lausiying0324 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277301491 We collected data of the average wind speeds, temperatures and relative humidity in Singapore.]]> 2018-09-03 12:38:50 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277301491 Secondary Data for Relative Humidity lausiying0324 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277303326 Credits:https://goo.gl/images/WHd2R2]]> 2018-09-03 12:50:04 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277303326 Secondary Data for Wind Speed lausiying0324 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277303606 Credits: http://www.weather.gov.sg/climate-climate-of-singapore/]]> 2018-09-03 12:51:57 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277303606 Secondary Data for Temperature lausiying0324 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277304482 Adapted from Google]]> 2018-09-03 12:58:09 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277304482 Reflection lausiying0324 https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277311590 Our group should've done the recording at around the same timing on both days to get more accurate results. We can also do it at more locations around the school.

We felt that there wasn't enough time for us to complete the project. However, this allowed us to learn how to manage our time.]]> 2018-09-03 13:26:11 UTC https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/277311590 Instruments Used jie_min_geraldine_tham https://padlet.com/whyluvvu0608/12mfsh1vbauw/wish/280619336 Sling Psychrometer
Relative humidity is measured using a sling psychrometer, which consists of a wet bulb thermometer and a dry bulb thermometer. To calculate:
1.Dip the wick of the wet bulb in water and swing the psychrometer for 1 min.
2.Record the reading. Repeat step 1 until both readings are consistent.
3.Read the temperature off the dry bulb.
4.To obtain the depression of the wet bulb, calculate the difference between the wet bulb temperature and the dry bulb temperatures.
5.Using the conversion table, obtain the relative humidity by finding the value where the wet bulb depression intersects with the dry bulb temperature.
