Brief Description

Calculate the difference between average summer and winter temperatures for 15 locations around the world.

Objectives

Students will

• calculate the difference between average summer and winter temperatures for 15 locations around the world.
• create a map to illustrate the temperature statistics.

Keywords

world map, temperature, summer, winter, average

Materials Needed

Lesson Plan

By how much do temperatures vary in your part of the world between summer and winter? The chart below shows average January and July temperatures in 15 cities around the world.

In addition, there is a spot on the chart to record your own communitys average January and July temperatures. (We recommend using the Weatherbase Web site as your temperature source.)

Provide a copy of the chart for your students. They can work on their own or in pairs to calculate the difference between the average January and July temperatures in the 15 locations listed on the chart. The differences in temperature are shown in red on the chart below.

After students have completed the work sheet and you have checked/gone over their work, provide a copy of a world map [see sources below]. Have students locate on their maps each location on the chart. At each location, they should record the average high temperature in red, the average low temperature in blue, and the difference in those temperatures in black. For example, at the spot where Anchorage, Alaska (U.S.A.) is located, they will record

Use the completed maps to illustrate and talk about how temperatures differ north and south of the equator. Students will note that temperatures south of the equator are warmer in January and cooler in July, which is the opposite of how temperatures adjust north of the equator. You might use the video below to help students understand how Earths tilt on its axis creates the seasons.

Assessment

Use the chart above to check student work (temperature differences shown in red type).
Check students maps for accuracy.
