LESSON PLAN

TOPIC:  Temperature Vs Latitude

OBJECTIVES:

1) Knowledge (Understanding Concepts):

  • understand the relationships between location and climate (BGA)

2) Skills:

  • use statistical methods effectively when analyzing geographic information
  • draw complex graphs from large, complex data bases. (GA)
  • observe relationships in the data such as distribution patterns (BGA)
  • write an explanation of the conclusions reached in a study of a cause and effect relationship. (G)

RESOURCE MATERIALS:

  • An atlas with Canadian content.
  • Average July temperatures for 19 selected Canadian settlements.
  • Graph paper

INSTRUCTIONS:

  1. Ask the students if they generally believe latitude and July temperatures are related.
  2. Using an atlas, have students complete the latitude column of the chart.
  3. Have the students carefully write a statement of the nature of the relationship between latitude and July temperatures.
  4. Using graph paper, set up the vertical and horizontal scales i.e. latitude: 40°N to 90°N (Horizontal); temperature: 0° to 20° (Vertical)
  5. Have students plot the values (use a number code- 1 to 19- to identify the settlements).
  6. Complete the exercise (review trend lines, if necessary)

COMPLETION TIME:

Approximately 30 minutes.

EVALUATION:
  • Completion of task data.
  • Apply to another set of climatic data.

ADDITIONAL QUESTIONS:
  • Discuss the exceptions of Aklavik and Iqaluit and the role of climatic factors. i.e. ocean currents

CORRELATION INQUIRY

-LATITUDE VS JULY TEMPERATURE-

QUESTION:
  • What is the relationship between latitude and July temperatures in Western and Northern Canada?

PART A: Introduction

Using an appropriate source complete the latitudes column for the attached chart, then complete the following tasks:

  1. Focus by making a prediction about any relationship between latitude and average July temperature. ______________________________________________________
  2. Construct a scatter graph.
  3. Draw an approximate line of best fit (trend line) on the graph.

PART B: Conclusions
  1. Draw conclusions about any correlation between latitude and average July temperatures, including any exceptions
