Scientific Investigations

1. A student carried out an experiment to investigate the relationship between the change in length (y) of a spring and the mass (m) of a load placed on the spring. 2. The student measured the change in length of the spring for different masses and recorded the data in a table. 3. A graph of y against m showed that y increased linearly with m, indicating the change in length of the spring is directly proportional to the mass of the load.
