Part B: Simulate Deforestation
Next, you’ll build a simulation showing the changes in a portion of the forest over time. This sample shows a forest region.

Forest Region

A 3 by 4 grid of rectangle blocks. 2 are black and 10 are gray.
Gray: untouched region (150 trees per block)

Black: deforested region (no surviving trees)

Use your word-processing program’s table maker to create three grids showing the rate of deforestation of a forest in three different years—year 1, year 5, and year 10. Choose colors to represent the deforested and untouched regions. Provide a key that shows the number of trees represented by each block, as well as the colors that represent the forested and deforested areas.

Here are the specifications for your forest:

The forest is represented by a 5 x 5 grid.
Year 1: There are a total of 4,500 trees in your forest and no deforestation. Figure out how many trees represent each block.
Year 5: 1,080 trees were deforested.
Year 10: An additional 1,980 trees were deforested.
After you’ve completed your grids, use the Insert Image button to insert screen shots of the grids in the answer space.
