PRESENTATION OUTLINE
Chemistry
Chemistry is a branch of physical science that studies the composition, structure,properties and change of matter.
Matter
Anything that has mass and takes up space.
Mass
The measure of the amount of matter in a object. Mass is usually measured in grams or kg.
Weight
Weight is the name of the force exerted on an object due to the acceleration of gravity.
Scientific method
A method of research in which a problem is identified relevant data are gathered. A hypothesis is formulated from these data and the hypothesis is imperially tested
Observation
When you use one or more senses
Qualitative data
Data that approximates or characterizes but does not measure the attributes characteristics properties.
Qua-native data

Hypothesis

Constant
Happening again and again
Control
To verify or regulate a scientific experiment by conducting a parallel experiment or by comparing with another standard.
Conclusion
The end or close. Final part.
Model
Scientific model can be material,visual, mathematical, or computational or often used in a construction scientific theory.
Theory
A scientific theory is a well sí stained explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly confirmed through observation.
Scientific law
A phenomenon of nature that has been proven to invariably occur whenever certain conditions sexist or met. Also called natural law.
Pure research
Research carried out for the purpose of better understanding fundamental concepts within a scientific field, rather than in search of a particular commercial goal.
Applied research
Refers to a scientific study and research that seeks to solve practical problems.
Technology
The use of scientific knowledge to solve practical problems, especially in industry and commerce.
