C.  DOUBLE BUBBLE MAP

Double Bubble Map is a great way to organize your thoughts when you are comparing and contrasting two things. In the middle you put how the two objects are alike. On the sides you put how the objects are different.  We can compare and contrast a Books, People, Objects, Animals, Places,Music, Events, etc.

   What are the similar and different qualities of these things?

• ·         What qualities of each thing correspond to one another? In what way?

• ·         Thinking process:

1.      This map is useful in comparing and contrasting two

2.      things. It allows for qualities that are shared to be placed in

3.       between the two items while differences are placed on the

4.      outside of the items.

5.      Unlike the bubble map, the words in the circles do not

6.      need to be limited to adjectives. You may use any words

7.       phrases that are appropriate.

8.      Color coding the similarities/differences may make the

9.      relationships more obvious to see.

• ·         How to create this map :
  1.    Near the center of your work space write the names of the two things that are being described. Each item should be in its own circle with space between the circles for detail
  
  
  2.   In the middle of the two things being compared, write the common qualities. Each quality should have its own circle and should be connected with a line to the original item circles.
  3.    On the outside of each original circle, you should write descriptions that are unique to each item. Every idea should each have its own circle and should only be connected with a line to what it describes.
