An experiment in science class was conducted to determine the time it takes different types of fruit to spoil in darkness. each piece of fruit; an orange, an apple, a pear, and a banana were placed in different dark rooms at different temperatures. the table shows the observations collected by the students after five days. which best describes an error the students made in the experiment? a) five days is too long b) too many types of fruit c) only done in dark rooms d) different room temperatures

Answer is: D) different room temperatures.

If students want only to measure influence of darkness to fruit, they should not change temperature, because now they will have two different impacts on on fruit spoilness.

The two main variables in an experiment are the independent (in this example should only be darkness) and dependent (spoilness of the fruit) variable.

Dependent variable is the variable being tested and measured in a scientific experiment.

Dependent variables depend on the values of independent variables. The dependent variables represent the output or outcome whose variation is being studied.

the correct answer is boyle
