In the first law, an object will not change its motion unless a force acts on it In the second law, the force on an object is equal to its mass times its acceleration In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction

Scientific thinking refers to both thinking about the content of science and the set of reasoning processes that permeate the field of science: induction, deduction, experimental design, causal reasoning, concept formation, hypothesis testing, and so on

“Laws are descriptions — often mathematical descriptions — of natural phenomenon; for example, Newton’s Law of Gravity or Mendel’s Law of Independent Assortment These laws simply describe the observation Not how or why they work, said Coppinger২৯ জুলাই, ২০১৭

Scientific laws are short, sweet, and always true They’re often expressed in a single statement and generally rely on a concise mathematical equation Laws are accepted as being universal and are the cornerstones of science They must never be wrong (that is why there are many theories and few laws)

Laws of physics

• Conservation laws
• Laws of classical mechanics
• Laws of gravitation and relativity
• Thermodynamics
• Electromagnetism
• Photonics
• Laws of quantum mechanics
• Radiation laws

Scientific models are representations of objects, systems or events and are used as tools for understanding the natural world Models can help scientists communicate their ideas, understand processes, and make predictions

The scientific method is used in all sciences—including chemistry, physics, geology, and psychology The scientists in these fields ask different questions and perform different tests However, they use the same core approach to find answers that are logical and supported by evidence

A good scientific question is one that can have an answer and be tested For example: “Why is that a star?” is not as good as “What are stars made of?” 2 A good scientific question can be tested by some experiment or measurement that you can do

When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory৪ আগস্ট, ২০১৭

As a reminder, here are the steps to the method:

1. Identify the problem The first step in the scientific method is to identify and analyze a problem
2. Form a hypothesis
3. Test the hypothesis by conducting an experiment
4. Analyze the data
5. Communicate the results

The first step of the scientific method is the “Question” This step may also be referred to as the “Problem” Your question should be worded so that it can be answered through experimentation Keep your question concise and clear so that everyone knows what you are trying to solve২০ জানু, ২০২১

A problem can be regarded as a difference between the actual situation and the desired situation This means that in order to identify a problem the team must know where it is meant to be and have a clear understanding of where it currently is in relation to the perceived problem

Scientific Method for Data Analysis that can also be applied to other aspects of life

1. Question This method starts with a question
2. Background Research As a follow up to the question, you should do a background research
3. Construct a hypothesis
4. Test the hypothesis
5. Analyze results and draw conclusion
6. Reporting results
