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
c. Test another variable
d. Share their conclusion
