Year 7 Introduction to Science-What is Science and Branches of Science Notes

 
 What is Science?
Science is all about finding out about nature and how things work. It is about investigating the reasons behind happenings around us. It is about questioning and finding answers to questions such as What? How? Where? Why? It is about finding explanations to strange, mysterious, and complicated things so we can have a better understanding of things. The work of scientists helps us to explain and understand how things work. Scientists are always asking questions and then finding the answers. Scientists are curious people finding out about everything around them. Scientists apply their knowledge and follow a systematic way based on evidence to find to solve problems and find answers to their questions. This systematic way is called Scientific Method. Scientists design, plan and conduct experiments and based their evidence on observations and data they have collected. They work in teams, share knowledge and communicate their ideas and solutions to problems.Scientists and branches of science

Scientists work in various areas of scientific study and listed below are some of the main areas of scientific study.

  • Biology is the study of living organisms.
  • Chemistry is the study of atoms and properties of substances.
  • Physics is the study of matter and properties
  • Earth Science is the study of layers (constituents) of the earth and its atmosphere.

The above mains areas are subdivided into more specific areas of scientific study:

For example, branches of Biology are:

  • Ecology is a branch of biology that deals with how living organisms interact with one another and to their environment.
  • Zoology is the scientific study of animals.
  • Botany is the scientific study of the plants.
  • Physiology is the branch of biology that deals with the normal functions of living organisms and their parts e.g human nervous, digestive, circulatory, respiratory, excretory, immune systems. (more information).

Astronomy is the branch of physics that involves the study of stars, planets and other celestial objects. Mechanics is the branch of physics that deals with energy and forces. (more information)  

Petrochemistry is the branch of chemistry which deals with the transformation of crude oil (petroleum) and natural gas into useful products and raw materials. (more information)
