Preparing a Map: Part 2 

Materials that you will need:   the outline map you made in Map: Part 1

Procedure to follow:

  Using the outline map you have already made, you will now add the plants.
  On your map, you will draw circles to represent trees and shrubs.
  The size of the circle will show the relative size of the tree or shrub.
  First you must determine where the plants are in you biotic community.
  Then you must transfer this information onto your map.
      Here's how:

1. Look at the example map below.  Each circle represents one plant.
   If you were floating in a balloon above your area and looked down,
   the plants would be in the same place as indicated on your map.


PART ONE:  ADD THE TREES
2. Stand at one corner of your biotic community.
    On your map, this will be one corner of the outline.
3. Pick a tree that you want to add to your map.
3. Walk along the side of your community, taking measured steps.
4. When the tree you are looking at is directly to one side, stop walking.
    COUNT the steps that you took.  Write the number down.
5.  Now face the tree and walk towards it, taking measured steps.
     COUNT the steps it takes to reach the tree.  Write the number down.

   Transfer this data to your map.  Here's how:
1. Get your outline map.
2. Start at the same corner that corresponds to where you started walking.
3. Count across your map the same number of marks as steps that you took.
4. Now stop.
5. Go into the map the same number of marks it took to get to the tree.
6. Put a dot there.
    This dot represents the trunk of the tree that you just walked to.
7. Go back to the tree directly and measure its crown.
8. How many steps is the diameter of the crown.
    Look up as you walk the distance.
9. On your map, the width of the circle around the dot represents the tree's crown.
10.  Do steps 1 - 9 for each plant you want to add to your map.

PART TWO:  WRITE THE CODE NAMES
1. Choose a code for your plants.
   Look at the example map above.
   PP means "palmetto palm", O means "oak", P means "pine".
   The code makes it easier to write their names on the map.
   There isn't enough room for all of the real names.
   That's why we use a code.
2. Make up your own code for the trees and shrubs.
    Use letters from their real names
    Write the code names on your map for each tree.
    This way, we will know which plants are on your map.

FOR THIS ACTIVITY, YOUR DATA IS YOUR COMPLETED MAP.
