The experiment that would use quantitative data from the options provided is "determining the densities of various objects."
Quantitative data involves numerical information that can be measured and analyzed. In this experiment, density is a quantitative property that can be determined by measuring the mass and volume of different objects. By collecting specific numerical values for the mass and volume of each object, you can calculate the density using the formula Density = Mass / Volume. This process involves precise measurements and numerical calculations, making it a clear example of using quantitative data.
On the other hand, the other options involve qualitative data:
1. Recording color changes during chemical reactions involves describing and observing visual changes, which are qualitative in nature.
2. Determining which cookie is best for dunking would involve subjective opinions and preferences, making it a qualitative assessment.
3. Recording a student's taste preference for flavored waters is also subjective and based on personal opinions, falling under qualitative data analysis.
