Activity: A team should be constructed which consists of doctors other healthcare workers. in addition to this there should be equipments such as the measuring tape and X-ray machine . the X-ray of each of the following students who carry heavy backpack are to be noted. The deviation of the spinal cord to the opposite direction should be noted to start as a result of this if there is any deviation of the spinal cord resulting in injury it should be noted. any pain in the back or the lower back should be noted and adequate treatment should be given. a similar comparison will be made on students who carry lesser weight.
Observations:it is seen that the occurrence of spinal disease or back pain are more in case of students who are are carrying heavy weight like the higher school students as compared to the children whose bags are carried by their parents on the books are comparatively light

Answer:
Make observations or inferences: In school, most students carry a backpack. Students frequently complain that their backpacks are heavy or hurt their backs.
Ask questions: Do students who carry heavier backpacks report more pain than students who do not?
Construct hypotheses and make predictions: Students who carry heavier backpacks are more likely to experience pain in their back at the end of the school day.
Test hypotheses: Get a sample of students in the school to help with the experiment. All students in the experiment would be students from the school and have no known back conditions. Then weigh the students’ backpacks, and ask the students if they have back pain at the end of the day.
Analyze results: Record the data in a table, and then organize the information by the weight of the backpacks. Group the backpack weights in five-pound intervals (five pounds, ten pounds, etc.) and use a bar graph to show the yes and no responses to the pain question for each student.
