Question

what is science and some example of science

Answer 1

Science is the study of the physical and natural world through observations and experiments. Science is all around us. Right now, the fact that you exist and are in the process of reading this lesson is science. The process of creating the air we breathe - also science. The food we enjoy, water we drink, and clothes we wear are all based in science. Looking up into the atmosphere gives us a glimpse into astronomy, another branch of science. You can't get around it. Science is everywhere and is one of the most important topics of study in our world.

Answer 2

Science is the field of giving rigorous answers, but ironically the definition of "science" is itself not rigorous.

Science is:

Processes for creating models for reliable prediction and control of the natural world;

Models created using those processes; and  

Application of those models.
