Winkler Method is a classical method(titration method) for determine the dissolved oxygen(BOD).
Starch solution is used in the Winkler method to act as an indicator for the presence of oxygen. When titrating the sample with iodine, the starch solution forms a blue-black complex with the iodine in the presence of oxygen, providing a visual endpoint for the titration. This helps to accurately determine the amount of dissolved oxygen in the sample.
An organized process for gathering observations is the scientific method. The scientific method consists of steps that help researchers get accurate information about research.
The steps of water cycle include:EVaporation of waterCondensationPrecipitationThe water is recycled using this method.
This process is called the Scientific Method.
A procedure is a series of steps or actions that are followed in a specific order to achieve a particular result in a systematic way. It is a set of instructions to carry out a task or experiment in a methodical manner.
The correct steps for the scientific method are: Observation Hypothesis Theory Scientific Law

you might need to complete the steps of the scientific method in a specific orderso you dont get the wrong answer.
Purpose then Hypothesis
what are 5 steps of scientific method first to last
So they can get a more accurate answer
So they can get a more accurate answer
Scientific method
No ,you can perform scientific Method in any order. Some of the greatest scientist use the scientific method in different orders, which makes them successful.
