In this section move from the results to the theory. If you set out to identify an unknown metal by finding its lattice parameter and its atomic structure, you'd better know the metal and its attributes. Compare your results to similar investigations. In some cases, it is legitimate to compare outcomes with classmates, not to change your answer, but to look for any anomalies between the groups and discuss those. Analyze the strengths and limitations of your experimental design.
Conclusion can be very short in most undergraduate laboratories.
Notice that, after the material is identified in the example above, the writer provides a justification. We know it is nickel because of its structure and size. This makes a sound and sufficient conclusion. State what's known 2. State significance 4.
