Front 1

- is a systematic study that is concerned with facts and principles, and methods that could be observed in our natural or physical and social environment. It comes from the Latin word 'scire' that means 'to know’. - is both a body of knowledge and a process – away of thinking, a way of solving problems

SCIENCE

Front 2

The study of matter and energy and the interactions between them. Physicists study such subjects as gravity, light, and time. Albert Einstein, a famous physicist, developed the Theory of Relativity.

PHYSICS

Front 3

The science that deals with the composition, properties, reactions, and the structure of matter. The chemist Louis Pasteur, for example, discovered pasteurization, which is the process of heating liquids such as milk and orange juice to kill harmful germs.

MEDICINE

Front 13

Is the logical method used by scientists to acquire knowledge that is used to explain different phenomena in nature. A thing observed by the senses is called a phenomenon; a scientifically tested observation is called a fact.

a. Identify and clearly state the problem.

b. Gather information pertinent to the problem.

c. Formulate hypothesis.

d. Test the hypothesis.

e. Draw a generalization or conclusion. f. Apply the principle (conclusion) to other situations.
