Question

An experiment was conducted to determine how the temperature of water effects the rate that sugar dissolves. The containers where stored at different temperatures. The data table shows the observations recorded by the students.

Which best describes an error the students made in the experiment?

A) used different types of sugar

B) used different water temperatures

C) different times were recorded by students

D) the sugar was weighed in grams instead of cups

Answer 1

The only answer is A)

Answer 2

The mistake the student made was using different types of sugar, therefore, the answer is A.

The experiment requires that you use different water temperatures to determine how the temperature affects the speed at which the sugar is dissolved, which also means that time must be recorded. It also doesn't matter how the sugar was measured, as long as you stay consistent when converting.
