            Definition of matter and energy:

      Energy: Every thing in the universe that has ability to do work.

      Matter: Every thing in the universe that has mass and volume.

Matter also can classify in to two              Matter      .

1.2   : Branches of Science: Science has four basic branches, they are 

1.       Biology   Chemistry   Physics    Mathematics

 The first and the best branch and also our favorite course is the biology

1.3   : What is biology? Bio: life          and          logy: science                   Biology:  life science

We can define it like that:  Biology is a branch of biology that study with living tings.

1.4   : Branches of Life Science:

      Life science is one major branch of science. It deals with living things and their relationship to one another and to their environment.

      Life science can be divided into a number of specialized branches. One branch of life science is zoology. Zoology is the study of animals. Another branch  of life science is botany , which is the study of plants. A third branch of life science is ecology, or the study of the relationships between living organisms and their environment. Still another branch of life science is microbiology. Microbiology is the study of microorganisms, or microscopic organisms.

      Just like any branch of science, life science has many special terms that may be unfamiliar to you. The list below gives the meanings of some prefixes and suffixes that are commonly used in science vocabulary. If you learn the meaning of these prefixes and suffixes, learning new science terms will be easier. For example, suppose you are reading a magazine article and you come across the term osteology. You know that the prefix osteo- means bone and the suffix –logy means study. By joining the meaning of the prefix and suffix, you learn that osteology is the study of bones.
