Match the following

• engineering

• if an apple fell from a tree it would be seen to move towards the center of the earth with a specified and constant acceleration.

• evidence

• applies scientific knowledge to design processes, structures or equipment.

• prediction

• understanding and studying phenomena in the natural world

• claims

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

• scientist

• statements made in science based on an experiment.

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

• analyze

• conclusion

• hypothesis

• reasoning

a statement based on experimental measurements and observations. It includes a summary of the results, whether or not the hypothesis was supported, the significance of the study, and future research.

• analyze

• conclusion

• hypothesis

• reasoning

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 .

• analyze

• conclusion

• hypothesis

• reasoning

The (a)   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

• Prisms
• spectroscopes,
• analyzing
• emit
• internal

The ​ (a)   scale is convenient for scientists, because a temperature change of ​ (b)   is the same size as a change of 1 K. To convert from one scale or another, all that scientists have to do is ​ (c)   or subtract ​ (d)   degrees.
