What is Science
An ongoing and changing discipline
What is Pure Science?
Experiments that lead to more about the world.
SI?
International System of Units
Scientific Notation?
A value written as a simple number multiplied by a power of 10.
Why do Scientists perform experiments
Find a new aspect of the natural world, explain a known phenomenon, check the results of other experiments, and test the predictions of current theories.
What is Technology?
Application of Science for practical uses like medicine and autocorrect.
Line Graphs?
MOST OFTEN USED IN SCIENCE, DISPLAY DATA THAT IS CHANGING, and TWO VARIABLES.
Significant Figures?
The value reported for a measurement is rounded off so that it contains only the digits known with certainty plus one uncertain one, which is the last digit.
Two main branches?
Natural Science and Social Science.
What does the Scientific Law describe?
A process in nature that can be tested by repeated experiments.
Bar Graphs?
TO COMPARE DATA FOR INDIVIDUAL ITEMS and use for easy comparisons.
Significant Figure Rules?
To determine the number of significant figures in a reported value, start at the left and count all digits beginning with the first non-zero digit.
Life Science is also called what?
Biological Science
The Kinetic Molecular Theory states what?
Molecules are in constant motion.
Pie Charts?
To display data that are parts of a whole.
Biology has multiple categories
Botany, Ecology, and Agriculture
What is Biochemistry?
Study of how Chemistry affects living things.
What is a model?
A representation of an object or event.
Accuracy vs Precision
Accuracy – a statement of how close a measured value is to the true or accepted value.
Precision – a statement of how reproducible the measured results are.
Laws, Theories, and Models
Difference: Laws describe what happens (often with math), theories explain why it happens, and models are representations/visualizations
Alike: They all use data to explain the natural world, but differ in purpose
