1. What is Science?

2. Core Concepts
Science is a way of thinking about and understanding your surroundings
Measurement is used to accurately describe properties and events
An equation is a statement of a relationship between variables
Science investigations include collecting observations, developing explanations, and testing explanations
Scientific laws describe relationships between events that happen time after time

3. Measurement is used to accurately describe properties and events
Measurement is a process of comparing a property to a well-defined and agreed upon referent
When standards are established, the referent unit is called a Standard Unit
NIST
English units and Metric units
International System of Units, SI

4. SI
Length

Length
Volume = L x W x H
Height
Units cubed because of 3-D
Width
Length

6. Data Measurement information used to describe something
Data can be used to describe objects, conditions, events or changes that might be occurring

7. Scientific Method Question raised or problem presented Data gathered
Hypotheses proposed
Predictions made
Predictions tested
hypothesis that withstands testing becomes a theory
