amount of space in a given volume
dependent variable
factor that we can measure or record in an experiment

a graph that shows circles that are "sliced" apart to represent percentages of the total for particular groups or categories
procedure
specific step-by-step instructions for how to conduct an experiment
qualitative data
These are observations that describe something. These would include characteristics such as texture, color, shape, and do not involve counting or measuring.
quantitative data
involves counting or measuring using standard scales
question
It is created after an observation; it is what you want to answer by the end of the experiment.
report
Sharing our results so that someone else can repeat our experiment.
research
