Plan how to investigate this question:

Choose variables that might affect

the outcome.

For each variable:

–   identify at least one way of obtaining data.

–  then decide the best way of collecting   reliable data for the variable.

Work out how to use the data to decide if using your phone will  damage your neck.

6) Calculate the force on your neck from the time you spend with your phone, combined with the angle of your neck and look if that exceeds the force limit required for damaging your neck
