The missing aspect from the experimental design is determining the procedure. While the student has identified the need to measure boiling points and to conduct the investigation multiple times, a clear procedure outlining how to carry out the experiment (such as how to heat the samples, how to measure the temperature accurately, and how to ensure consistent conditions) is essential for replicability and reliability of results.
A student decides to conduct an investigation to determine the boiling points of water and ethanol. The student will heat samples of water and ethanol, and measure the temperature at which the samples boil. The student will conduct the investigation three times. Which aspect is missing from the experimental design?(1 point)
