The researcher is confounding the sweetness of the cereal and the colour of the cereal.
Explanation:
Based on the results, it would be unclear if the subjects prefer the cereal because of the colour or because of the sweetness --it is only the latter the researcher wants to know about. This would be the dependent variable.
To fix this, the researcher should use the same colour for both sweetened and unsweetened cereal and have each preschooler try both. It is possible to colect data through observation (look at the children's reactions) or simply asking for their opinions at the end of the experiment.

The college course component in which you practice with specialized equipment is called a lab.
A laboratory is a facility that provides controlled conditions in which scientific or technical research, experiments, and measurements can be conducted. Testing services are provided in a variety of settings, including clinics, clinics, hospitals, and regional and national referral centers.
Lab is an abbreviation for Labor, from the Latin Laborare, from the medieval Latin root labatorium, "a place for work or labour." Many scientists and researchers commute to the lab every day (often wearing a "white coat," a white coat that protects their clothing).
