solid
An organized approach to solve problems
The Scientific method
a type of science which studies the composition, structure, and properties of matter
chemistry
grinding, cutting, and melting are examples of this
physical change
anything that has mass and takes up space
matter
when a substances changes its state
change of state
This typically has "if, when statements"
A hypothesis

hairspray
a feature that can be observed at without changing the substance's identity.
physical property
this mixture does not have a uniform composition
heterogenous mixture
does not have a definite shape but has a definite volume
liquid
This part of the scientific method must have every step to the procedure so it can be repeated by other scientists
An Experiment
