Chapter 1
A way of learning about the natural world
What is science?
The three main branches of science
What are life science, physical science, and Earth science?
This visually organizes and displays information in rows and columns for easier comprehension.
What is a table?
The SI unit for length
What is the meter?
This type of graph uses bars of different sizes to show relationships between variables; one variable is divided into parts; the other variable is a number.
What is a bar graph?
The practical use of science
What is technology?
A rule that describes a pattern in nature
What is a scientific law?
A description of how close measurements are to each other
What is precision?
The SI unit for time
What is the second?
These images show an object exactly as it is at a single moment.
What are photographs?
Factors that can be changed in an experiment
What are variables?
The three basic types of models
What are physical models, computer models, and idea models?
A comparison of measurement to actual value
What is accuracy?
The SI unit for mass
What is the kilogram?
This graph element usually reads, "The dependent variable per the inderpendent variable."
What is the title?
An attempted explanation for repeatedly observed patterns in the natural world
What is a scientific theory?
Collections of structures, cycles, and processes that relate to and interact with each other.
What are systems?
An approximated measurement based on previous experience
What is an estimation?
The SI unit for volume
What is the cubic meter?
This type of graph shows relationship between two variables, which must be numbers
What is a line graph?
A representation of an object or event used as a tool for understanding the natural world
What is a model?
This procedure is done by observing, questioning, and researching; forming an hypothesis;
predicting an outcome; investigating; analyzing; forming conclusions, communicating findings;
and repeating the process.
What is the scientific method?
These reflect the true precision of a calculation
What are significant digits?
The SI unit for temperature
What is the kelvin?
The number we "skip count" by on the horizontal or vertical axis of a graph. These must be carefully constructed and analyzed so users easily understand the information.
What is the scale?
