Scientific Method

2. method of watching for the outcome of an experiment.
5. Something made up of one or more atoms.
8. a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena.
9. what happens in and experiment
12. also called reliability.
16. the portion of an experiment that may be changed in order to observe reactions and compare conclusions.
18. factual information collected during an experiment through testing or observation, which is then used as a basis for reasoning, discussion, or calculation.
19. A quality, characteristic, or trait of a thing or person. For example the texture of food.
21. The movement of molecules and ions from places where there are lots of them to places where there are fewer of them.
22. an educated guess, based on your knowledge and experience, about what will happen in an experiment
23. The portion of the experiment which remains constant throughout any variable changes, allowing an experiment to study one variable at a time.

1. The movement of water molecules across a barrier, such as a cell membrane, that lets some (but not all) kinds of molecules through.
3. one of the primary goals of the scientific method is to ----- -------(2 words)
4. When scientists conduct experiments, their "--------" are the people whose reactions or responses they are studying.
6. The portion of an experiment which occurs in response to the change in the independent variable(s).
7. a tentative assumption made in order to draw out and test its logical or empirical consequences. Often referred to as and "educated guess."
10. an operation or procedure carried out under controlled conditions in order to discover an unknown effect or law, to test or establish a hypothesis, or to illustrate a known law.
11. scientist change or ----------- the independent variables during an experiment to test their ideas.
13. a plan that is followed in performing a scientific experiment and writing up the results.
14. what food feels like in your hand or in your mouth.
15. reasoning used to move from premises to conclusions, where the conclusion must be true if all the premises are true.
17. When the subjects of an experiment do not know what is being tested.
20. The extent to which the measurements of a test remain consistent over repeated tests of the same subject under identical conditions. An experiment is reliable if it yields consistent results of the same measure.
