Lab 2: Holy Pigeon P$#! Batman, it's Penelope Poison!
We are still working on editing this wiki page (Im progress :))
Problem Description and Approach
Our task as the Yellow Team was to collect data on various water bodies in London in order to gauge the possible effects of releasing a toxic substance into London’s water supply. Dr. Obfuscation only provided photographs of the 11 locations where Penelope Poison threatened to release the toxic substances. We needed to figure out the geographical coordinates (latitude and longitude) of these locations, measure the air and water temperature, our elevation and note the wind speed plus direction at the times we are at these locations Most importantly, we needed to figure out what the most accurate approach to collecting this data was, and what if any flaws there were in collecting this data. Time was also a factor to keep in mind, so we decided to tackle the location not in alphabetical order, but in the order of their proximity to one another.
Air and Water Temperature using the Maplin thermocouple thermometer
Sources of error that we experienced in collecting air and water temperature were both mechanical and human errors. Although we dried the rod after each reading the rod may still have been chilled which may have affected the results of the next air temperature reading. As far as documenting water temperatures we experienced problems with accuracy due to an inability in some locations to immerse the rod without it being in contact with stone. Also the varying depth of the bodies of water may have had some effect on the accuracy of the readings.
Wind Direction using a compass and Tesco plastic bag
It was hard having the compass on a flat surface in some areas as most readings were taken while it was on someone's palm ( a surface that is not even). In addition, regular compasses are not made to point exact North, but relative North which a point with a particularly strong magnetic pull. Therefore many of the objects we identified as being North or South of the water bodies might not have been so, if we were looking for a precise bearings. When experiencing light winds, a Tesco plastic bag might prove to be denser than the wind thus making it impossible to show which direction the wind is moving. Using objects that have a similar density to air, such as dyed smoke or cigarette smoke might be more efficient in showing much lighter winds.

Appendix C: Who Did What
Eva Marengo My contribution to the lab was taking the water and air temperature readings and helping record the data. At each location I took three readings of the water and of the air. In the lab report I did the associated write up. I also assisted at navigation and finding the perspective of the photos taken in order to replicate them.
Vivian Bateyunga My contribution to the lab was collecting data on wind direction using a basic compass and a Tesco plastic bag. I also described what was North and South of the location of the water body. I assisted with copy-editing the lab write up and figuring out the averages for the raw data collected.
Sandra Mamus Ngeseyan I was the principle data-recorder for the group and also helped determine what the wind-speed at each location was. It was extremely important that my handwriting was neat and the recording of data was done in an organized fashion. I helped to write up the description of the lab, as well as gather information from different members of the group.
