A well- supported and widely accepted explanation of nature
Scientific Theory
numerical data
Quantitative data
a statement about a cause-and-effect relationship that will occur under specific conditions, based on prior knowledge, observations, and reasoning
Prediction
a representation of an object or a process that allows scientists to study something in greater detail
Model

List the difference between each of the 3 main types of graphs
Bar Graph: used to display and compare data in a number of separate categories
Line Graph: used to show continuous change over time
Circle Graph (Pie Chart): used to show how each group of data relates to all of the data

Empirical Evidence
refers to how close measurements of the same item are to each other.
Precision
List the last 3 steps of the scientific method
Collect, organize and analyze data

Share Results
List the 4 components of a graph
1.) Title of the Graph
2.) Axis Labels (include unit measurements)
3.) Data (use an appropriate unit scale for both axis
4.) Graph Key (when necessary)
What step of the scientific method is it most important to use universal measurement and why?
collecting data because they are used for consistency between scientists from across the world
