Living things : organisms
Study of structure and functions of living organism
Catology – study of structure and function of cell.
Anatomy – study of internal structure
Biochemistry – study of chemistry of organisms
Study of change and development in living things
Genetics – study of heredity and genetic variation
Paleontology – study of extinct organisms
Study of living things and environment
Ecology – study of organisms : environment, adaptation and interaction
Study of living things
Zoology – study of animals
Botany – study of plants
Microbiology – study of microorganisms
Taxonomy – study of the classification of living and extinct organisms
IDENTIFYING A PROBLEM
Also call PROBLEM STATEMENT
In the form of a QUESTIONS
Eg : “ What is the effect of different sugar concentration on the expansion of dough? ”
FORMING A HYPOTHESIS
Connect together the concentration of sugar (manipulated variable) and the dough rise (responding variable) in a relationship that is testable.
Eg: “ The higher the concentration of sugar in the dough, the more the dough rises”
Only include the manipulated variable and responding variable and their relationship to each other.
PLANNING THE EXPERIMENT
Preparation of control test
The quantity of materials and apparatus required
List of controlled variables.
How and When to vary the manipulated variable and How and When to record the responding variable.
What to label and How to label the test sets
Set-up the materials and apparatus.
Precautions and The sequence of steps.
CONDUCTING THEEXPERIMENT
Carry out the experiment following the sequence that you have listed
COLLECTING DATA
Data is recorded in the table of data.
Sometimes you need to culculate the average value
ANALYSING DATA
Data are represented in the form of table, histrogram, pie chart, graph with axes, bar chart, etc.
Easy to inteperated
INTEPERATING DATA
Identify trends, patterns, and relationships between manipulated and responding variables to make inferences
