Science Basics
It is the branch of science that involves the study of the physical world: energy, matter, and how they are related.
Physics.
It is the number of reliably known digits in a number.
Significant Figures.
It is a process used by scientists to investigate, predict, and draw conclusions about the world around them.
The Scientific Method.
It refers to the repeatability and exactness of the measurement using a given instrument.
Precision.
What is the multiplier for the SI prefix “milli-”?
10-3
It is a statement about what happens in nature and seems to be true all the time.
A Scientific Law.
It is used to simplify the handling of very large and very small values by powers of 10.
Scientific Notation.
It is the variable that depends on the independent variable in an experiment.
The Dependent Variable.
It refers to how close a measurement is to the true/actual value.
Accuracy.
What is the multiplier for the SI prefix “tera-”?
1012
It is an explanation of things/events based on many observations and investigations.
A Scientific Theory.
Leading zeros on the left are significant.
It is the variable that is manipulated in an experiment.
The Independent Variable.
It quantifies the difference between an estimated or measured value and the actual or true value, expressed as a percentage.
Percent Error.
What SI prefix goes with the multiplier 10-6?
micro-
It is the representation of an idea, structure, or object that helps better understand it. It is often used to represent things that are too large or too small to observe normally.
Trailing zeros on the right are significant when the number contains a decimal point.
Yes. True. Always.
What are the three base quantities that we will talk about the most this year?
Length, Mass, and Time.
In an experiment, it is important to have a high level of:
Precision and Accuracy.
