Vocab Quiz 1

Question 1

Quantitative Data

Answer 1

Quantitative data is information about quantities that can be measured and written down with numbers.

Question 2

Qualitative Data

Answer 2

Qualitative data is a categorical measurement expressed not in terms of numbers, but rather by means of a natural language description.

Question 3

Model

Answer 3

A systematic description of an object or phenomenon that shares important characteristics with the object or phenomenon.

Question 4

Weight

Answer 4

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Density is mass/volume.

Question 5

Independent Variable

Answer 5

A variable is any factor, trait, or condition that can exist in differing amounts or types.

Question 6

Dependent Variable

Answer 6

A dependent variable is what you measure in the experiment and what is affected during the experiment. It is called dependent because it “depends” on the independent variable.

Question 7

Conclusion

Answer 7

Key Info. Your conclusions summarize how your results support or contradict your original hypothesis.

Question 8

Control

Answer 8

A standard of comparison for checking or verifying the results of an experiment.

Question 9

Hypothesis

Answer 9

In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis.

Question 10

Applied Research

Answer 10

Basic research means that research directed toward increasing knowledge in science.

Question 11

Theory

Answer 11

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.

Question 12

Experiment

Answer 12

a. A test under controlled conditions that is made to demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried. b. The process of conducting such a test; experimentation. 2.

Question 13

Pure Research

Answer 13

Basic research, also called pure research or fundamental research, is scientific research aimed to improve scientific theories for improved understanding or prediction of natural or other phenomena.

Question 14

Mass

Answer 14

In physics, the property of matter that measures its resistance to acceleration. Roughly, the mass of an object is a measure of the number of atoms in it. The basic unit of measurement for mass is the kilogram.

Question 15

Substance

Answer 15

A substance is matter which has a specific composition and specific properties. Every pure element is a substance. Every pure compound is a substance. Examples of substances: Iron is an element and hence is also a substance.

Question 16

Scientific Method

Answer 16

a method of research in which a problem is identified, relevant data are gathered, a hypothesis is formulated from these data, and the hypothesis is empirically tested. Origin of scientific method Expand.

Question 17

Chemistry

Answer 17

the science that systematically studies the composition, properties, and activity of organic and inorganic substances and various elementary forms of matter. 2. chemical properties, reactions, phenomena, etc.: the chemistry of carbon. 3. a.

Question 18

Scientific Law

Answer 18

A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements.
