Answer and ExplanationSolution by a verified expert

Explanation
Science deals with the study and analysis of different types of information. In order to resolve a scientific problem, the facts related to the problem are identified and studied. Whatever information is gathered from the recognition of the problem is called observation. In science, this step is called creating an observation. Suitable and possible explanations are stated in light of the observation. The set of possible explanations is termed hypotheses. In science, this step is renowned for stating different hypotheses. Out of all the possible hypotheses, the one that successfully explains the different types of observations is converted into a theory or model. This step requires a sequence of actions to be performed in order to prove the authenticity of the explanation. These actions are collectively referred to as experiments. In science, this step is renowned for generating a model by performing experiments. The entire procedure from making observations to formulating theories is referred to as the scientific method. Once a theory has been well tested, it becomes a law.

Making an observation is the first step in resolving a dilemma. The observations where numbers are not involved are called qualitative observations. Few instances of qualitative observations that are made around the school or home are as follows:

Observing differently colored flowers near the home and school
Observing different types of vehicles moving around the home and school
Observing different pets and animals around the home and school
Observing the color of clothes worn by different individuals present in the vicinity of the home and school
Observing different fast food stalls in the vicinity of the home and school
On the other hand, the observations where the involvement of numbers takes place are called quantitative observations or measurements. This suggests that numbers are included in the value of a given measurement. Few instances of measurements made in daily life are as follows:

Counting the number of students in each class of the school
Measuring the amount of spices added in the preparation of a dish (in tablespoons)
Measuring the length of the path taken to reach from home to market (in meters, kilometers, or other units)
Keeping a check of the volume of water consumed in a day (in liters or milliliters)
Keeping a record of time spent in doing different activities such as studying, playing, cooking, and others (in minutes or hours)
Sample Response
Five instances of qualitative observations include the observations made for distinctly colored flowers, different vehicles, different pets and animals, different colors of clothes worn by people, and different food stalls present near the home and school.

Five instances of quantitative observations include the count of the number of students in all the classes of a school, measurement of the amount of spices added in a dish, measurement of different paths between home and market, measurement of the volume of water consumed in a day, and measurement of time spent in daily activities.
