Materials

The materials required for this science fair project:

-    10 boys 13 years of age
-    10 girls 13 years of age
-    20 glasses of milk
-    40 cookies
-    20 MP3 players
-    2 sets of Mathematics test papers of equal difficulty
-    An examination hall with tables and chairs
-    A stopwatch

Procedure

1.    For this science fair project, the independent variable is the gender of the participants and whether the test is done while multitasking. The dependent variable is the average time taken by the students to complete the 2 tests. This is determined by measuring the time taken by the students to finish the tests and calculating the average time taken by all of the students. The constants (control variables) are the age of the students, the difficulty of the math test and the number of questions to be answered.

2.    Select 10 boys and 10 girls age 13, to take part in this science fair project. Prepare 2 sets of Mathematics test papers and make 20 copies of each test paper.

3.    On the 1st day of the experiment, have the 20 students brought into the examination hall and have them take the math test. Record the time taken for each student to complete the test. Calculate the average time taken by the participants to complete the test, and record your calculations according to their gender in a table, as shown below.

4.    On the 2nd day of experiment, bring the 20 students into the exam hall again. Place a glass of milk, 2 cookies and a MP3 player on each of their tables. Tell the students to listen to the MP3 player, drink the milk, eat the cookies and complete the Mathematics test at the same time. Record the time taken by each student to complete the test. Calculate the average time taken by the boys and girls to finish the tasks, and record your calculations in a table, as shown below.
