EFFECT ON SLEEPDid you know that sleep can be strongly affected by electronic devices?
Research shows teens who use social media during bedtime could be getting less sleep and could possibly make them depressed and anxious. The screen light from the phone prevents melatonin (a hormone that helps you sleep) from working. A screen’s blue-ish light is recognized by cells in the back of your eyes that send a message to your brain that it's morning time. Most Apple devices have a “night shift” button which turns your screen from a blue-ish light to a warmer color that is supposed to be easier on your eyes. But studies have shown that screens affect your sleep because of not only the light but the fact that people using devices during bedtime can have a harder time “shutting their brain off.”

THEN AND NOW PHONE EVOLUTION"Mr. Watson--come here--I want to see you.” Sound familiar? If not, it was the first words spoken into a telephone.
The first phone call was spoken by Alexander Graham Bell. He was calling his assistant Thomas Watson. Alexander's splendid invention lit up our world and inspired many others to build off his invention and eventually create what we have today…. cell phones. Cell phones are part of 6.8 billion people's life (almost as many people as there are on earth!) and not only teenagers but many other people take advantage of how lucky we are be able to have access to such a wonder of technology without even touching the science of a phone. Phones have changed a lot since then, as you can see on the next page. The next page shows images of how phones have changed and how they look on the inside over the years.
