Materials

The materials required for the science fair project experiment:
- 10 boys and 10 girls aged between 12  and 15 years.
- 10 flash cards each containing an animal name
- A story about 300 words long and containing 10 names of different animals
- A quiet room to conduct the test
- 40  blank sheets of paper
- 20 pencils
- A stop watch
- An assistant

Procedure

1. For this science fair project, the independent variable is the 10 animal names on the flash cards and the story  containing 10 animal names. The dependent variable is the ability of the children to remember the names of the animals. This is determined by asking the children to write down the animal names that they can remember.  The constants (control variables) are the time they are allocated to look at the words, the time given to write the names, the number of animals needed to be remember and the speed at which the story is read to the students.

2. The 20 students are brought into the room where the tests will be conducted. They are made to settle down and get familiar/comfortable in the room. The students are given an explanation regarding the 2 tests and what they are required to do.

3. The testing is started by showing the students the cards with the names of animals. Each card is shown to the students for only 10 seconds. The time is measured by the assistant using the stopwatch. After all the 10 cards are shown, the students are given a 5 minute break. After the break, the students are given a piece of paper and a pencil  to write down the names of the animals that appeared on the card. After 3 minutes, the papers are collected back.

4. The second test is performed by slowly reading a short story containing the names of 10 animals. After the story reading, they are again given a 5 minutes break and asked to write the names of the animals after the break. After the 3 minutes the papers are collected back.

5. The total number of correct animal names recalled by the students is recorded in the table given below.
