Cell phoneCell phones are used by more than 3 billion people worldwide.[1] From text-messaging teens in the United States to pre-paid phone users in developing nations, cell phones have revolutionized the way people connect with their world.

Despite their popularity, however, some argue for restrictions on cell phone use because of possible health and safety risks, especially among children and teens. Others say that the danger is minimal and that benefits provided by cell phones exceed their risks. Both sides point to scientific studies to bolster their conclusions about the safety of cell phone use.

Is it better to err on the side of safety and limit the use of cell phones, or is it more important to let users decide for themselves after weighing the risks? What kind of restrictions on mobile phone usage, if any, might be appropriate to protect human health given current scientific knowledge?

MichiganScience will award a cash prize of $500 to the student (in grades six-12) whose 500-word essay best explores the science surrounding the health effects of cell phones and compellingly advocates for or against restrictions limiting mobile phone use.

Runners-up will receive gift cards good for thousands of fun and interesting products from Edmund Scientific, a premier supplier of science kits and other educational materials.

All essays must be original, legible and no more than 500 words in length. Authors must be in grades six through 12. Each entry must include the attached submission form. The deadline for entries is April 1, 2009. Winners will be announced in May 2009. The winning essay will be published in the Summer 2009 issue of MichiganScience.
