Materials

The materials required for this science project are as follows:
- 40 cell phones
- 10 dried corn seeds
- 20 participants

Procedure

1. For this science fair project, the independent variable is the number of cell phones used. The dependent variable is whether or not the corn is popped by the cellphone radiation.. The constants (control variables) are the number of dried corn seeds used, the distance between the corn seeds and the cell phone, and the power of phone signals.

2. 20 participants and 40 cell phones are used. Each participant is to be given 2 cell phones. He/she is to use 1 phone to make a call. The second phone is placed next to the corn seeds.

3. The first test is done using 2 cell phones. The dried corn seeds are placed in the center with the phones and their antennae pointing towards it. The distance between the cell phones and the dried corn seeds is approximately 5cm. Participants will dial the 2 cell phone numbers and allow cell phone to ring for 5 minutes. During that time, observe whether the dried corn seeds cook. The result is recorded in the table below.

4. The test in procedure number 3 is repeated using 5 phones. Then, 10 phones are used concurrently. Later, 15 phones are used. Finally, 20 phones are used concurrently. The cell phones are arranged in a circle around the dried corn. Extra cell phones can be stacked on top of each other. The distance between the dried corn seeds and the cell phones is kept at 5 cm.
