Lab 2: Holy Pigeon P\$&! Batman, it's Penelope Poison!

Overview

London is in a pickle, and it's your job to help them out of it. The notorious Penelope Poison has threatened to release a toxic substance into London's water supply, in order to thwart her plan the emergency response people need visualizations which show the water temperature, air temperature, wind speed and direction, and pH of a number of water bodies located in central London.

You will all need to show-up at location 1 (see Questions below) before/at 11:00 on Sunday morning. I will be available starting at 9:30 at that location to hand-out instruments, answer questions, etc. At least one person from each group should plan on being there before 11:00. I will be leaving that location at 11:15 sharp so stragglers will need to hope their group waits for them.

Lab Groups

Listed below are your scientifically chosen lab groups:

• Red: Lily, Bill, Emily, Ben
• Yellow: Mamus, Ivan, Vivian, Eva
• Green: Krystnell, Johanna, Spencer, McKayla

• Black: Gillian - The steps leading from the sidewalk into the courtyard of the museum devoted to cooling oneself.
• Purple: On the sidewalk near the marque of the home of Greenwich's thespians.

Details

• Identify where each image was taken.
• At each of those locations record the following:
  1. A picture that duplicates as near as possible the one you were given of the location.
  2. The latitude, longitude and elevation of the location (if you have a GPS in your kit use that, if not use Google Earth).
  3. An estimate of the wind direction and speed when you are there.
  4. The water temperature or the pH of the water (depending on which instrument kit you have).
  5. The air temperature.

Remember to record at least three readings for each parameter at each location. Later you can aggregate each of those groups of three readings into a measurement of that parameter for that location. Think about how to "reset" each instrument so you can record three independent readings of each parameter.

To measure the wind speed you can estimate it using the Beaufort scale.

Measuring the air temperature will depend on which kit you have. The thermocouple and the combination compass/thermometer can take direct readings, the infrared thermometer will require a little cleverness to enable it to measure the air temperature (hint, you might want to bring a small piece of aluminum foil and a glove with you).

Red Instrument Kit

• GPS
• Infrared thermometer (aluminum foil, glove)

Yellow Instrument Kit

• GPS
• Thermocouple thermometer

Green Instrument Kit

• Combination compass/thermometer
• pH meter

Report

Your lab report should include the following elements:

1. A description of the problem you were given and your approach to solving it.
2. For each parameter the procedure you followed to obtain the readings and measurement.
3. A short statement from each group member explaining what they contributed to this lab.

Visualization

Each group will be able to create a visualization with the parameters they measured.

Questions

Before you start and once you folks are working on the lab I will be available to answer questions, etc., here's where to find me when:

1. Between 09:30 and 11:00 you can find me at roughly 51.510509, -0.127060
2. Between 11:30 and 14:30 you can find me at roughly 51.502998, -0.165623
3. After 15:00 you can find me at roughly 51.511393, -0.127091

I won't be checking email or text messages between 11:00 and 15:00 but I will be available for F2F consultation at the locations/times listed above.

descriptive not proscriptive, except maybe for the end result (the viz)?

All locations sampled by two completely independent teams

All locations water temperature with infrared and regular thermo, pH, ?

All locations air temp with regular thermo (orange) and ?

They figure-out how to calibrate all the instruments ice and boiling water for temp documented procedure for pH

Normally you would take water and air samples too (editorial footnote)

Organize yourselfs, one big group? No, two groups that cover the whole thing, ensures ability to compare different people, or, 4 groups?

Each site has to be sampled by two completely different groups of people. Readings and measurements kept separately and then aggregated into data to use in the visualization (that is easy to do each set separately if need be).

deadline of 19:00 that day and dinner together afterwords? One weeks worth of class, mon and tue prep, sat data and assembly, dinner on Sunday 19:00 with presentation of results?

What can you hypothosize about the macro level water flow in London from the data you collected?
