If there is not one scientific method, then what do all scientists have in common???
Plsss I will give brainliest, and 12 points !!

Answers

Answer:

One thing that all scientists have in common is that they find problems in the world, and attempt to seek answers to those problems. Everything that scientists do begins with observations, leading to questions.

Let me know if this helps!

While no single scientific method is uniformly followed by all scientists, there are certain common aspects and concepts that scientists share in their search of knowledge and understanding.

These are some examples:

Scientists rely on empirical evidence gathered via observation, experimentation, and measurement.

Systematic and Objective Investigation: Scientists explore and analyse events using systematic and objective approaches.

Scientific discoveries should be repeatable, which means that other researchers should be able to replicate the tests and achieve identical results.

Thus, although scientists' methodologies and approaches differ between fields, these basic principles drive their research and contribute to the collective growth of scientific knowledge.

Answers

Answer:

Scientists use  models to represent data/evidence. However, all models have limitations. However, models are simplified versions of reality, and can't be totally accurate in representation.

Hope this helps :)

Answer:

Since models are simpler than real objects or systems, they have limitations. ... It may not predict the behavior of the real system very accurately. But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.
