Changes can be brought about by new scientific discoveries, but they can also be influenced by social, political, or religious beliefs.
What is scientific ideas?A scientific idea is a scientific explanation of how something works or the truth about some aspect of the world that was discovered through the scientific process.
Science is the process by which we make sense of the world by collecting data and conducting experiments. As our evidence improves, scientific ideas evolve.
A scientific theory is a well-supported explanation of some aspect of the natural world based on a simplicity of facts which have been cross checked repeatedly via observation as well as experiment.
Such fact-supported theories are not guesses, but rather reliable accounts of reality.
As our evidence improves, scientific ideas evolve. The more experiments we conduct and data we collect, the more refined our scientific theories become.
Thus, due to this the scientific ideas sometimes change.

Why do scientists use models, and why do all models have limitations???
Plsss help! :) I will give brainliest!! :)
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.
If there is not one scientific method, then what do all scientists have in common???
Plsss I will give brainliest, and 12 points !!
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.
