INTRODUCTION:
A field is a region in which there is a definite physical property that can be measured at every point, On
Earth's surface there are hundreds of different measurable quantities. Some examples of measurable
field quantities are; air pressure, temperature, elevation, rainfall amounts, and humidity.
During your course of study you will see many different types of field maps. ln this lab we will be iniroduced to field maps using temperature data in the classroom.
OBJECTIVE:
You will use data from temperature values for two diflerent days in a classroom and construct isotherms to interpret the field map.

PROCEDURE A:
Using Map A: [Jecember 21st, construct isotherms using "lo C intervals for the known temperature data
provided on the rnap. Ignore the points with letters, tirey will be used in the discussion questions.
PROCEDURE B:
Using Map B: June 21st, construct isotherms using '1' C intervals for the known temperature clata provided on the nrap. lgnore the points with letters, they v,;;ll be used in the discussion questioris.

DISCUSSION QUESTIONS:
1.
ls the temperature field map a static or dynamic field?
2. Do the isotherm maps represent
a two dimensional or three dimensional map?
3.
Will the December 21st have the same appearance tomorrow?
4.
Using Map A: December 21st, calculate the gradient between points A and
work and labelthe units properly.
5.
Using Map B: June 21st, calculate the gradient between points C and
and labelthe units properly.
6,
What factors may have caused the temperature variations in the classroom?
7.
What could have caused the difference in the appearance of Map A and Map B
