1
Q

what is science

A

a collection of knowledge and a process of discovering how various parts of the universe interact with each other

2
Q

Physics

A

is the study of forces and energy.

3
Q

Chemistry

A

the study of atoms and molecules, their structures, and their interactions to form various substances

4
Q

Earth science

A

Earths structure and composition, as well as the process that change earth such as volcanic and seismic activity.

5
Q

physical science

A

studies non-living organisms

earth science, chemistry, physics

6
Q

life science

A

studies living organisms

7
Q

Atoms

A

extremely small particles that make up All living and non-living things. Atoms are so small they cannot be seen with an ordinary microscope. when these particles bond together they make a wide variety of molecules.
Atoms and molecules make up every substance we know.

8
Q

variables

A

changing quantities in an experiment

9
Q

dependent variable

A

the one that changes because of the independent variable

10
Q

independent variable

A

is the one that is being changed or controlled by the experimenter

11
Q

control(constant) variable

A

the variables that need to be either eliminated or kept constant (these are not being studied)

12
Q

controlled study

A

an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.

13
Q

observational study

A

can be done with our own senses (sight, hearing, smell, taste, or touch) or by using tools (telescopes, radiation detectors, multimeters, etc.).

In observational studies, the systems are observed as they appear in nature and researchers do not attempt to change them.

14
Q

field study

A

collection of raw data outside a laboratory, library, or workplace setting. The approaches and methods used in field research vary across disciplines.

15
Q

physical model

A

is a smaller or larger physical copy of an object used to study the larger scale.

16
Q

conceptual models

A

can be used to visualize things that cannot be seen, such as atoms.
The main goals of a conceptual model are to capture the essential features of the system that it represents and to be easily understood by those who use the model.

17
Q

mathematical models

A

treat physical objects or phenomena using mathematical methods. In these models, pertinent physical characteristics are represented using formulas, graphs, or other mathematical means.

18
Q

principle of falsification

A

for a theory to be considered scientific it must be able to be tested and proven false.

19
Q

hypothesis

A

an educated guess or prediction that might explain a phenomenon.

  • is based on real data with little supporting evidence.
  • relies on the principle of falsifiability.
20
Q

scientific law

A

A law is a concise statement based on many experiments or observations.

  • supported by all data and observations
  • descriptions of natural phenomena
  • generally rely on a mathematical equation
21
Q

Theory

A

is a statement that explains a wide range of observations and that is supported by a large body of scientific evidence. It explains how and why things happen
