Step by stepStep 1: Put your scale on a hard surface. Make a list of people and record the person weight.Step 2: Record the weight of each backpack.Step 3: Calculate 10% percent of each persons body weight. Compare this number to the actual weight of the backpack. If their body weight percentage is larger than the weight of the backpack, it is too heavy.

variabesI used the same scale to measure each person all though each person had a different backpack the styles were similar. Observations Most students carry all their books for the entire day.The students do not have enough time to go to their lockers in between classes to exchange and put away books.Students are not able to carry just the books needed therefore they have to carry more books.
