Qualitative property explained to kids

A qualitative property is a property that can be observed and measured without changing the composition of the substance it is being measured on. For example, the color of a substance is a qualitative property. Other common qualitative properties include texture, density, hardness, and odor. In order to measure a qualitative property, scientists use their senses to observe and describe the substance. For example, when measuring the color of a substance, a scientist would look at the substance and describe its color. Once the scientist has described the color, they can then compare it to other colors in order to find a match. Qualitative properties are important in the field of science because they help scientists to identify and describe substances. By measuring and observing qualitative properties, scientists can learn a lot about a substance without changing its composition.
