## Comparison of the ability of boys and girls to identify facial expressions |

The materials required for this science fair project:

- 10 boys, 15 years of age

- 10 girls, 15 years of age

- 25 photos of facial expressions compiled into a test paper

- A computer

- An examination hall with tables and chairs

- A stopwatch

1. For this science fair project, the independent variable is the gender of the participants. The dependent variable is the number of facial expressions identified correctly by the students. This is determined by checking the answers given by the students. The constants (control variables) are the age of the students, the number of different facial expressions given to them to identify and the time given to them to identify the expressions.

2. Randomly select 10 boys and 10 girls age 15 to take part in this experiment. Search the internet for 25 photos of faces making different facial expressions. Compile them into a test paper for participants to guess what each facial expression means. Number the pictures and provide blanks next to each picture. Make 20 copies of the test and create an answer key.

3. Assemble all 20 students in the exam hall. Distribute the test papers and give the students 1 hour to complete the test.

4. Mark the tests using the answer key and calculate the average score for each gender. Record your results in a table, as shown below.
