What do scientists use to make charts and to communicate the results of an experiment?
A chart or a graph is often used to present the numeric results
of an experiment. This makes much more clear the way one property
changes as the other changes.
For example, the change in density of water as it is heated.
These results will be communicated in words, explaining the
results obtained, and your conclusions which explain the behaviour.
Your graph will be included in the results.
