- 10 participants
- 80 flash cards

- 40 sheets of paper
- 10 pens
- a stopwatch


1. For this science fair project, the independent variable is the color of the flash cards. The dependent variable is the ability of the participants to remember the contents of the flash cards. This is determined by asking them to write down what they saw.  The constants (control variables) are the duration of time they are allowed to look at the flash cards and the number of flash cards used.
