Task One - Where are the Topical Grasslands?

Climate Classification Map

A4 VersionA4 Version | Google Earth Version Google Earth Version | Source
Using either the A4 Version or the Google Earth version of the World Map of Climate Classification mark the Tropical Grasslands (Aw) onto a blank world map. Ensure that your map has a title and a key.

Task Two - Produce a Climate Graph for a location in the Tropical Grassland

Produce a climate graph for a location in the Tropical Grasslands - Bujumbura, Burundi. You can find the necessary data by clicking on the banner below.
Google Earth Version Bujumbura, Burundi Placemark
Using Excel to Produce a Climate Graph

Step 1:
Open the Excel and in a cell near the top left type Month. Type January in the next cell, followed by February, etc.

Step 2:
Type Temperature (°C) in the cell below the word 'Month' and then enter the temperature data in the cells under each month.

Step 3:
Type Rainfall (mm) into the cell below the word 'Temperature' and then enter the rainfall data in the cells under each month.

Step 4:
Highlight all the data that you have entered and click on the Chart Wizard icon in the toolbar.

Step 5:
Choose the first type of Column graph and then carry on until you get to Step 3 of the wizard.

Step 6:
Type in the graph title e.g. Climate Graph of Anytown, then the x-axis label e.g. Months and then finally type in Rainfall (mm) for the y-axis.

Step 7:
Select the Legend tab at the top of the wizard and untick 'Show Legend'.

Step 8:
Click next and in Step 4 of the wizard choose the option ‘As new sheet’. Give it a name and click Finish.

Step 9:
The next task is to convert the temperature data to a line graph. Move your mouse over one of the temperature columns and right-click. From the option box that opens, choose ‘Chart Type’ and then ‘Line’ graph as the type of graph. The temperature data will then be plotted as a line graph.

Step 10:
The next task is to move the temperature line upwards. To do this, right-click on the line, choose ‘Format Data Series’ from the option box that appears, then select the Axis tab at the top and click on ‘Secondary axis’.

Step 11:
The final task is to add a label to the new y-axis on the right. To do this, click on the chart wizard again and move
through to Step 3. In Step 3, a new box should have appeared called ‘Secondary value (Y) axis’. Use this to enter a label for the temperature data e.g. Temperature (°C)

Step 12:
You can (after saving the graph) go back and alter any aspect of it e.g. the colours of the bars or lines, edit the title and axis labels, etc, etc.


Plotting Climate Graphs using Excel 2007

Geography ResourceTasksheet [Produced by Gareth Hunt]

Add another column to your summary table and then analyse your Tropical Grasslands climate graph.

The table should show the following pieces of information:

Hottest Month
Temperature (°C) of Hottest Month
Coldest Month
Temperature (°C) of Coldest Month
Wettest Month
Amount of rainfall (mm) during Wettest Month
Driest Month
Amount of rainfall (mm) during Driest Month

Task Three - Understand the Tropical Grassland food web

A food web is a summary of known feeding relationships in an ecosystem. A food web illustrates how each type of organism in an ecosystem is typically consumed by or consumes more than one other type of organism, and that different types of organisms compete for the same food sources. A food chain is a linear sequence of organisms in which each is food for the next member in the sequence.

Extension Task - Produce a food web for the Tundra

Complete some research and then use Google Image Search to find images of organisms found in the tundra ecosystem and then produce a tundra food web using an application such as PowerPoint.
