Ipads Research Paper

In addition, H eavy backpacks cause serious back pain to students, so why don't replace textbooks for ipads or tablets? Every year many young students develop back problems due to the weight of backpacks. A normal backpack of an average high school student weights around ten to twenty pounds, an ipad weighs around 1.5 pounds, * A study conducted by Brandon Macias of UCSD Department of Orthopedic Surgery concluded that students carry backpacks loads of twenty-two percent of their body's weight and it is only recommended to carry fifteen percent at most*.Also in many schools teachers have an very big problem; the orthography problem , so if books and notebooks are replaced by ipads or tablets this problem can be finally solved. Not only that
but also over fifty million trees are chopped down to make textbooks per year, that's only in the united states of America, Four billion trees are chopped down yearly around the world.
