Terms, Concepts and Questions to Start Background Research

  • What is a control?  A control is the variable that is not changed in the experiment.
  • What purpose does a control serve? It is used to make comparisons as to what changed or possibly caused the change.
  • What are variables?  Variables are factors that can be changed in an experiment.
  • What is an independent variable? The independent variable is the one that is changed in the experiment.
  • What is a dependent variable? The dependent variable is the one that changes as a result of the change in the independent variable.

Charting and Graphing Data

In each section of the experiment, use this chart to display the obtained data from the analysis of the pictures produced by the right brain directions and the left brain directions.  Summarize your findings and graph your results. Remember, a picture, in this case, the graph is worth a thousand words!

Subject #'s 1-10

Amount of Detail Left Brain (H,M,L)

Amount of Detail Right Brain (H,M,L)

Resemblance to Original Left Brain (H,M,L) Resemblance to Original Right Brain (H,M,L)

Experimental Procedure

  1. State the problem you are going to investigate in this science fair project.
  2. State your hypothesis and your rationale for this hypothesis.
  3. Reproduce the data sheets you will use to record your observations.
  4. Reproduce the pictures the subjects will use.
  5. Make ten packets of drawing paper, picture to be copied, a twelve inch ruler and pencils for distribution.
  6. Select ten classmates of the same gender and age as subjects.
  7. Provide them with the following directions: your task is to copy the picture you have been given twice. Once, you will place the picture right side up and copy it. You have 15 minutes. Then, you will place the picture upside down, use a ruler to move it upward, copying each segment above the ruler and focus on the lines, the angles and the shapes of the empty spaces. Forget the names of the objects in the picture. Just focus on the space and lines and shapes and angles. You have 15 minutes.
  8. Collect both sets of papers. Using the chart above, record your data as you analyze each of the papers in terms of the following two criteria, the amount of detail in each picture as high , medium or low, using H, M,and L  and the degree to which the copied pictures resemble the original, again using high, medium or low,H, M,and L. Summarize your findings.
  9. Prepare your report and include all of the following: a clear statement of the problem and your hypothesis, List the materials used. Describe the procedures used. Include all the data that were gathered. Include the chart and graphs. Formulate your conclusions. For dramatic value, you may include photos of the materials used or of your subjects in the process of conducting these investigations well as sample drawings. Include a bibliography of sources you used. You may wish to assess what you did and describe what you would do differently if you were to do this project again. Think about how you could expand this research as to gender and age as variables in this context.
