What is the scientific method?

• The scientific method is a systematic approach used by scientists to investigate and understand the natural world.

• The scientific method is a process used by scientists to prove their hypotheses.

• The scientific method is a random and unstructured approach used by scientists to study the natural world.

• The scientific method is a set of rules that scientists must follow in order to conduct experiments.

What is a hypothesis?

• A proposed explanation or prediction that can be tested through experimentation or observation.

• A conclusion drawn from personal beliefs or opinions.

• A random guess without any basis or evidence.

• A proven fact that has been tested through experimentation or observation.

What is the difference between a theory and a hypothesis?

• A theory is proven to be true, while a hypothesis is proven to be false.

• A theory is based on empirical evidence, while a hypothesis is based on speculation.

• The main difference between a theory and a hypothesis is that a theory is a well-established and widely accepted explanation, while a hypothesis is a tentative explanation that requires further testing and evidence.

• A theory is used to explain natural phenomena, while a hypothesis is used to make predictions.
