A conclusion states what the evidence supports, while an improvement changes a method to reduce a named error or increase confidence.
Distinguish random from systematic error and propose an extension that tests a new, answerable question.
If readings drift because temperature is not stable, use a thermostatically controlled bath and monitor it throughout.
“Repeat more carefully” is not an improvement unless it says what will be changed and why.
