The scientific method |
The scientific method is a process of investigation in which problems are identified and their suggested explanations are tested by carrying out experiments |
|

|
Steps in the scientific method |
observation hypothesis experimentation collection and interpretation of data conclusion relating the conclusion to existing knowledge reporting and publishing the results |
|
|
|
What is a Theory? |

|
|
|
