Experimental Procedure

  1. State the problem you are going to investigate in this science fair project.
  2. Obtain a fingerprinting kit.
  3. Obtain your subjects. These should be families, the larger the family the better. The greater the number of families you use the stronger will be your conclusions.
  4. Create the data sheets you will use to record your observations.
  5. Set up a place and a schedule for taking sample prints.  
  6. Take the prints by spreading ink on the pad, using the brayer to obtain a thin film, roll the finger and then print it.
  7. Repeat step 6 with all fingers on both hands.
  8. Label the prints and place in folder.
  9. Repeat steps 6 through 8 for all of your subjects.
  10. Review the sample prints for each family. Compare the prints. Note similarities and differences.
  11. Classify the prints in terms of categories of loop, whorl, arch or abstract.
  12. Review and summarize your data for each family.
  13. Formulate your conclusion. Were their similarities in all of the families you sampled?  Can you say that families do display similarities and that this is therefore useful information?
  14. Prepare your report and include all of the following: a clear statement of the problem and your hypothesis and the rational for your hypothesis. List the materials used.  Describe the procedures used. Include all the data that were gathered. Include all charts and graphs. Formulate your conclusions.   For dramatic value, you may include photos of the materials used or of you in the process of conducting this investigation. You may wish to display the various components of the prints.   Include a bibliography of sources you used.  In conclusion, you may wish to assess what you did and describe what you would do differently if you were to do this project again.
