, , , ,
  • Consistent (internally & externally)
  • Parsimonious (sparing in proposed entities, explanations)
  • Useful (describes & explains observed phenomena)
  • Empirically Testable & Falsifiable.
  • Based upon Controlled, Repeated Experiments.

What are the 4 requirements that makes something scientific?

  • Make an observation.
  • Ask a question.
  • Form a hypothesis, or testable explanation.
  • Make a prediction based on the hypothesis.
  • Test the prediction.
  • Iterate: use the results to make new hypotheses or predictions.

What are the requirements of a valid theory?

There are many definitions out there, but there is some common ground to them. They all tend to agree that a theory needs to be

(a) substantiated

, (b) explanatory, (c) predictive, and (d) testable.

What are the qualities of a good scientific theory?

  • Testable: Theories can be supported through a series of scientific research projects or experiments. …
  • Replicable: In other words, theories must also be able to be repeated by others. …
  • Stable: Another characteristic of theories is that they must be stable. …
  • Simple: A theory should be simple.

How do you know if a theory is valid?

In order to see if a theory is valid you could

use a scientific method to gather data to determine its

validity (Mosser, 2013). Once the data is collected and your point is made it is considered to be a theory.

What is the first step in the scientific method?

The first step in the Scientific Method is

to make objective observations

. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.

What makes a theory true?

A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. … A theory not only explains known facts; it also

allows scientists to make predictions of what they should observe if a theory is true

. Scientific theories are testable.

What are the 10 steps of the scientific method?

  • 1 – Make an Observation. You can’t study what you don’t know is there. …
  • 2 – Ask a Question. …
  • 3 – Do Background Research. …
  • 4 – Form a Hypothesis. …
  • 5 – Conduct an Experiment. …
  • 6 – Analyze Results and Draw a Conclusion. …
  • 7 – Report Your Results.

What are the 5 rules of science?

  • Act responsibly in the science classroom / lab. …
  • Follow all written and verbal instructions carefully. …
  • Never work alone. …
  • Do not touch equipment or chemicals in the lab until your teacher gives instructions.
  • Do not eat, drink or chew gum in the science classroom / lab.
  • Do not drink from lab containers.

What are the six basic steps of scientific method?

The six steps of the scientific method include: 1) asking a question about something you observe, 2) doing background research to learn what is already known about the topic, 3)

constructing a hypothesis

, 4) experimenting to test the hypothesis, 5) analyzing the data from the experiment and drawing conclusions, and 6) …

What are the 3 characteristics of a good theory?

One lesson is that the reason a “good” theory should be

testable, be coherent, be economical, be generalizable

, and explain known findings is that all of these characteristics serve the primary function of a theory–to be generative of new ideas and new discoveries.

What is scientific theory example?

A scientific theory is a verifiable explanation of natural phenomenon. For example,

the theory of gravity explains why an apple always falls to the ground when dropped

. A law, on the other hand, is an observation. In simpler terms, a law predicts what happens and a theory explains why.

What are good theories?

A good theory in the theoretical sense is (1)

consistent with empirical observations

; is (2) precise, (3) parsimonious, (4) explanatorily broad, and (5) falsifiable; and (6) promotes scientific progress (among others; Table 1.1).

Why is law accepted as fact but a theory is not?

Explain why a law is accepted as fact, but a theory is not. Theories are not accepted as fact because

new information or technology can show that the theory is incomplete or incorrect

. A law is accepted as fact because it is a statement of what will happen and no exceptions have ever been found.

What qualifies as a theory?

A theory is

a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method

, and which brings together many facts and hypotheses. … A scientist makes an observation of a natural phenomenon.

What is the difference between a hypothesis and a theory?

In scientific reasoning, a hypothesis is

an assumption made before any research has been completed for the

sake of testing. A theory on the other hand is a principle set to explain phenomena already supported by data.
