Please help asap :) i will give brainliest, too! A group of students is investigating whether aluminum is a better thermal conductor than steel. The students take an aluminum wire and a steel wire of the same length and diameter. They put equal lengths of wax on one end of each wire and dip the other end into a beaker of hot water. The length of wax left on the wires after 10 minutes is shown.

Which step should the students take next?

a. Make a hypothesis

b. Analyze the data
