During a research work, an effective and efficient way to follow the scientific method includes:
Make observations.
Ask questions.
Construct a hypothesis.
Test the hypothesis with an investigation.
Analyze the data.
Explain the result.
Communicate the result.
The scientific method is the variety of techniques that scientists use to observe, examine, investigate, and study the natural world and explain it based on evidence, theories, evidence, hypotheses, or factual information that scientists derive from their research work.
It can be defined as the scientific method usually involves combining traditional scientific processes with critical thinking, scientific knowledge, and reasoning to generate new ideas. Please note that if your hypothes is true, it should be shared with the community. However, if your hypothesis is wrong, you should build another hypothesis and repeat the process.

The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
(1)
Where:
- Final temperature, in degrees Celsius.
- Initial temperature, in degrees Celsius.
- Time, in minutes.
- Cooling rate, in
.
- Current temperature, in degrees Celsius.
Please notice that substance reaches thermal equilibrium when
, that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that
,
,
and
, then the cooling rate of the substance is:
