Topic :
OBSERVATIONS
Observation is the accumulation of reliable data to
discover what actually occurs.
Data are the observations recorded from an
experiment.
HYPOTHESES
These are possible guesses or explanations to our
observations given without experimental testing.

HOME
Topic :
EXPERIMENT
This is a test carried out under controlled c
onditions that is made to examine the validity of
a hypothesis.
THEORY
A theory is a statement formed to show that a
hypothesis is true.
THE SCIENTIFIC LAW
A scientific law is a statement based on repeated
experimental observations.
A law may fail due to new discoveries.

TopicCHEMISTRY
:
Definition of chemistry:
Chemistry is a physical science which studies matter, its
composition, structure, and their uses.
BRANCHES OF CHEMISTRY
Chemistry is usually divided into these branches;
1. Inorganic chemistry; This is the chemistry of materials
(non-living) other than those classed as organic.
2. Organic chemistry; is the study of substances cont
aining carbon. It is the chemistry of carbon compounds.
It was originally the study of substances from living
organisms.
