the study of matter and energy
the stuff of which things are made
the study of all forms of matter and how they interact
(properties, structure, how substances behave under different conditions, i.e. heat)
the study of energy and how it effects matter
(motion, force, gravity, electricity, light, sound)
a series of steps that scientists use to answer questions and solve problems
any use of the senses to gather information
possible explanation for a set of observations or possible answer to a scientific question
an "if-then" statement
a control group and an experimental group. both groups are the same except for one factor.

decide if data supports hypothesis
(sometimes data can be misleading)

a representation of an object or system
volume:basic unit-liquid and solid
volume of an irregular object
measure how much liquid the object displaces (1 ml=1cm cubed)
the amount of matter something is made of
a measure of how hot or cold something is
Quantities formed from combinations of other measurements are called
a measure of how much surface an object has
the amount of matter in a given space
steps of the scientific method
problem/question, observation, hypothesis, testing (experiment), data, analysis, [conclusion]
