# Science Reasoning Center - Reflection and Mirrors

There were two Reflection and Mirrors passages in the Legacy version that targeted students' science reasoning abilities. They have each been converted to a Version 2 activity. We have included the links below:

Concave Mirrors
This passage describes a collection of experiments in which students investigate the characteristics of images formed by a concave mirror. Information is presented in the form of two diagrams and a data table. Questions target a student's ability to analyze and interpret a complex diagram, to identify the effect of variations in one quantity upon another quantity, to draw conclusions that are supported by one or more data presentations, to identify evidence that supports a conclusion, to transform data in a table into a graph, and to interpolate and extrapolate from data in a table.

Object-Image Relationships
This passage describes an experiment in which students investigate the effect of the distance an object is from the mirror upon the height and location of the corresponding image. Data is presented in the form of two graphs. Questions target a student's ability to identify the effect of one variable upon another variable, to select values and to compare values on a graph, to draw conclusions that are consistent with a data presentation (or two), to combine data from two graphs in order to identify an accurate conclusion, and to interpolate using values on a graph.
