Mind mapping can be used to generate ideas for anything.
Begin with a pen and piece of paper or use a white board. (You can use different colors of pens or pencils to represent each subtopic.) Then find an idea you wish to explore.
Write down the idea in the middle of the page or whiteboard and circle the idea.
For each subtopic, draw a line from the circle and write it down the subtopic on the line.
For each fact, concept, or piece of information that is associated with a subtopic, draw a line from the subheading and write down the related detail.
Be sure to use simple words and phrases.
