Question

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.
Experimental Observations
Aluminum Steel
Original length of wax 2.5 cm 2.5 cm
Length of wax after 10 minutes 1.2 cm 1.8 cm


Which step should the students take next?
A. Make a hypothesis
B. Analyze the data
C. Test another variable
D. Share their conclusion

Answer 1

The students have conducted an experiment to check their hypothesis on the thermal conductivity of two metals; Aluminum and steel. The experimental observations have been noted, and the next step based on the scientific procedure is to analyze the data.

Analysis of data suggests that; since the length of wax after 10 min is lower in Al than steel, aluminum is a better thermal conductor.

Ans B) Analyze the data
