• serves to either support or counter a scientific theory or hypothesis

• engineering

• statements made in science based on an experiment.

• claims

• understanding and studying phenomena in the natural world

For example, scientists may predict that if the climate becomes warmer in a particular region, then the distribution of plants and animals should change.

Because data usually do not speak for themselves, scientists use a range of tools—including tabulation, graphical interpretation, visualization, and statistical analysis—to identify the significant features and patterns in the data. Sources of error are identified and the degree of certainty calculated.. Which word below goes with this .

The ________ is a typical instrument used to measure the mass of various objects. (answer in small letters only)

​ (a)   of this kind are used in certain ​ (b)   instruments for ​ (c)   light and for determining the identity and structure of materials that ​ (d)   or absorb light. Prisms can reverse the direction of light by ​ (e)   reflection, and for this purpose they are useful in binoculars
