Claim, Evidence, Reasoning
Statement believed to be true
Claim
Scientific process to carry out a well-controlled experiment to collect data or evidence to support or refute a claim
Scientific Method
In a solid,
definite/indefinite volume
definite/indefinite shape
Molecules are far apart/close together
Definite
Definite
Close together
d=m/v
Ability to dissolve
Solubility
Data that supports or refutes the claim
Evidence
Steps to follow in an experiement
Procedure
In a liquid,
definite/indefinite volume
definite/indefinite shape
Molecules move slow/fast
Definite
Indefinite
Slow
True or False
Density changes when you cut an object into pieces
FALSE
Density DOES NOT change because breaking an object changes is Mass and its volume
Force of attraction/repulsion to other materials
Magnetism
Data collected with your senses
Qualitative
Variable being tested
Independent
In a gas,
definite/indefinite volume
definite/indefinite shape
Molecules are far apart/close together
Indefinite
Indefinite
Far apart
Less dense gasses _______ (sink/float)
Float
How tightly packed molecules are
Density
Data collected with tools
Quantitative
What is being collected in an experiment
Dependent variable

Condensation
More dense gasses _______ (sink/float)
Sink
Pulled into wires
Ductile
Statement that connects the evidence to the claim to form a conclusion
Reasoning
List the 6 steps in the scientific method
