As per my hypothesis, I noticed that the weight in the student's backpacks also depends on the major the particular student is seeking. For instance a student majoring in Engineering has much more backpack weight as compared to students majoring in Kinesiology or Interior Designing since they have more textbooks to carry. I also learned that due to our advanced technology another major reason of heavy backpacks has been the weight of their laptops. Today a majority of students carry laptops, as they believe that it is more portable and easily accessible although it hasn't been declared as a university requirement. .
There are a few ways to reduce back and shoulder strain from backpacks and book bags. Backpacks should be no longer than the distance between the shoulders and hips, and no wider than the ribcage (Lucas, 2002). They should also be worn with both straps; this helps center the weight and does not put too much strain on one shoulder. Backpacks slung over one shoulder defeat the purpose of distributing the weight evenly. Shoulder straps should be wide and padded, and a waist or hip belt is highly suggested. (Lucas, 2002) Backpacks should be worn above the waist, and not low, which causes the bearer to slump forward to center the weight (Lucas, 2002). Heavier items should be packed closer to the back and lighter items farther away. Some students that use book bags and satchels are advised to switch to backpacks because the weight is put on only one shoulder. Following simple suggestions may relieve some back and shoulder strains. .
Although lockers are an alternative to heavy backpacks, there are advantages and disadvantages to having them on the school campus. Lockers reduce heavy backpacks during the school day, but not on the commute back and forth from home to school. Students have their own little private space to keep items, but weapons and illegal substances, such as drugs, can also be kept unless a daily check of all the lockers are made.
