# Rainfall and Elevation: A Charting and Critical Thinking Exercise

This material is replicated on a number of sites as part of the SERC Pedagogic Service Project

#### Summary

This Computer Technology lab is designed to engage students in the process of organizing and presenting data in a visual way so that they can then summarize in writing their conclusions about the relationships between the data.

## Learning Goals

Goals include:
• ability to create a chart from non-contiguous data spreadsheet
• label chart data to accurately describe the content
• copy data between programs
• describe in writing what the charts portray

## Context for Use

This is a Computer Applications activity appropriate for high school freshman. Access to a computer and a spreadsheet program capable of charting and a word processing program are needed. This assignment serves as a capstone to a group of charting activies. Prior instruction includes entering data in a spreadsheet, using the chart wizard, editing chart features, and applying and understanding a trendline. This activity will require an hour (likely more) depending on the student.

## Teaching Notes and Tips

Students may wish to enhance their charts by using an appropriate picture in the plot area or chart area background. Care should be taken to keep the chart easy to read. Review of the writing rubric prior to the writing portion of the assignment may help students.
