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

#### Summary

In this Spreadsheets Across the Curriculum activity, students create spreadsheets to convert units between and within the English and the metric systems. They work with units for temperature, volume and mass. The module includes a review of the basics about unit conversions and an introduction to spreadsheets for new users.

## Learning Goals

Students will

• Practice performing conversions of temperature, mass, and volume by developing spreadsheets to carry out the calculations.
• Develop spreadsheet skills including building formulas and creating graphs.
• Learn how to add a trendline to a graph and interpret the relationship between its slope and the conversion factor.
• Review the metric system and scientific notation.
• Use the TREND function to facilitate conversions.

In the process the students will

• Increase their ability to perform calculations using spreadsheets.
• Increase their skill at unit conversions.
• Acquire an understanding of the magnitude of metric units.

## Context for Use

This activity is intended for use in a first semester college course in chemistry, biology, earth science, or other class where unit conversions are used. It will be a review for many students. It is also appropriate for advanced placement classes.
