The Five Senses
We make observations every day, even when we don't realize it. An observation is knowledge that can be acquired using any of our 5 senses.
Sight is one of our five senses. This is when we see with our eyes. Some things we can see are: color, shape, and number of objects.
Hearing is another sense. We hear different sounds with our ears, such as a fire alarm or the crunching of a leaf that was just stepped on.
A third sense is the sense of touch. The four types of touch sensations are hot, cold, pain, and contact.
Smell is the sense we use our nose for. We can smell an odor or the scent of food.
We use our tongue for the sense of taste. The different types of taste are: sweet, sour, bitter, and salty.
Qualitative and Quantitative Observations
There are two types of observations: qualitative and quantitative. A qualitative observation describes a quality of an object, such as color or shape. A quantitative observation describes the amount of an object present, for example volume or mass.
