This exercise teaches you how to use Excel and Microsoft Map to draw a map that shows how fast the world's rainforests are being destroyed. It might seem complicated, so be patient and follow the instructions very carefully! It will be easier to try and keep both Excel and this web page open at the same time. Ready to go? 1 First you need to start Excel and copy all the data below (including the empty cells) into a new spreadsheet.
Data
from World Conservation Monitoring Centre 1997 and taken from Earthworks
2 teachers guide by John Widdowson and published by John Murray
2
Calculate the annual forest loss in km2 by multiplying the area
of rainforest by the annual rate of deforestation and dividing by 100.
Excel will do this for you if you do the following:
3 Click on cell D2 to highlight it, and then drag the small square in the bottom right side of the cell downwards to replicate the formula (do the same calculation for the rest of the data)
4
Highlight all cells containing data and click the map icon.
5 Excel hopefully draws a map of the world showing the countries in the spreadsheet! The map control box should be open:
The map shows the area of rainforest in each country - to change this to show annual forest loss, put the mouse over the annual forest button and a 'handle' appears. Drag the handle onto the grey box in the window underneath and the data on the map should change
6 Add and format a title for the graph by right clicking on the title and selecting "format font".
7 The colour of the shading on the map can be adjusted by clicking map / value shading options and selecting a different colour. Choose 4 in the box that shows number of value ranges. By now your map should look something like this:

There are several other things you can do with your map. Remove the
latitude and longitude lines from the map lines from the map to make
it easier to read. Click on the map with the right mouse button and select
features. Remove the tick from the world graticule box. You
can use the map labeller to label selected countries if you wish.
This is the button to use:
9
Try adding a symbol to show the amount of forest in each country.
Hint - use the map control box and drag the pink star symbol into
the format box. Now you can add the amount of forest data by dragging
it onto the star symbol. This will help you decide if countries with
more forest are have the most rapid deforestation rates. Here is an
example:
10 Add another calculation to your spreadsheet to show how long it might take each country to lose all their forests. Show this on a new map.
