Make A Double Bubble Map

Making a double bubble map is relatively easy.

A double bubble map is a thinking map that helps a student compare and contrast two subjects or ideas. The double bubble map consists of circles and lines. A column of circles at the center of the map connects the ideas, a single circle on either side of the column represents a separate idea, and the circles branching out from the single circle describe the separate ideas. In order to make a double bubble map, find two subjects that you want to compare and contrast, take notes about each of the subjects, draw the double bubble map, put in the information, and create a title.


1. Find two subjects that you desire to compare and contrast. Making a double bubble map can help you to understand the similarities and differences of the subjects in an easier way. For example, you may want to compare and contrast lemons and oranges.

2. Brainstorm about the idea. As you do this, write down facts about each individual idea, and properties that both ideas share. For example, lemons are yellow, sour and oblong. Oranges are orange, sweet and round. Both lemons and oranges are citrus fruits, nutritious and used for cooking.

3. Draw the double bubble map. Each circle of the double bubble map corresponds to a single concept. For example, draw three circles in a column. Then, draw one circle next to the center circle of the column on both sides. Draw a line from each side of the circles in a column, and connect it to the adjacent circle. Next, draw three lines branching from each circle on the end. Draw on circle at the end of each line.

4. Label the double bubble map. You can use your brainstorming notes to help you. For example, in the circles at the center of the double bubble map, write the properties that lemons and oranges share. You can write “citrus fruits” in the top circle, “nutritious” in the middle circle, and “used for cooking” in the bottom circle. In the outer circle on the right side, write “oranges.” In the outer circle on the left side, write “lemons.” In the circles branching from the “oranges” circle, write the one property of oranges in each circle. You can write “orange” in one, “sweet” in another, and “round” in the other. In the circles branching from “lemons,” you can write “yellow” in one, “sour” in another, and “oblong” in the other.

5. Create a title for the double bubble map. The title of the double bubble map should explain what you are comparing and contrasting. For example, the title for you fruit double bubble map may be “Lemons and Oranges.”
