14. Scientists use a general process known as scientific inquiry to ask and answer questions about
nature.
15. Using a type of logic known as inductive reasoning , a generalized conclusion can often be drawn
from a large number of specific observations.
16. A hypothesis is a proposed explanation for a set of observations. It leads to predictions that can
be tested by additional observations or by experiments.
17. Deductive reasoning uses “if…then” logic to proceed from a general hypothesis to specific
predictions of results that can be expected if the general premise is true.
18. A hypothesis must be testable and falsifiable - there must be some observation or experiment
that could show that it is not true.
19. A controlled experiment involved both an experimental group and a control group, which are

20. A theory is broader in scope than a hypothesis, is supported by a large body of evidence, and
generates many new hypotheses.
21. Observing what other students in your class are wearing is an example of discovery science.
22. Testing whether or not dead batteries are preventing a TV remote from working is an example
of hypothesis-driven science.
23. Observation, question, hypothesis, prediction, experiment : steps of the scientific method in
