Preparing a report

Steps 1 in a scientific method - Making observations

Using senses of sight, hearing, touch, taste or smell to gather information about an object or a phenomenon taking place

Steps 2 in a scientific method - Making an inference

Using data collection and past experience to make a conclusion and explanation about an event

Steps 3 in a scientific method - Identifying the problem

Asking questions based on the inference mad

Steps 4 in a scientific method - Making a hypothesis

Making a general statement about the relationship between a manipulated variable and a responding variable to explain an event or observation

Steps 5 in a scientific method - Identifying the variables

Identifying the manipulated variable,responding variable and fixed variable(s) in an experiment to test the hypothesis that is formed

Steps 5 in a scientific method - Controlling the variables

A variable is manipulated to observe its relationship with the responding variable and other variables are fixed

Steps 6 in a scientific method - Planning an experiment

Determining the materials & apparatus to be used, procedure of the experiment, method of collecting data and the ways to analyse & interpret the data
