# Integers and Science

Exploring Integers and Scientific Facts #### Introduction

There are many connections between integers and science. The boiling and freezing point of liquids, the melting and freezing points of solids, and the temperature of planets, are all expressed as integers. You have been selected to explore these connections.

To prepare for these explorations, you will need to browse our lessons on integers, completing the interactive exercises at the end of each. You will then complete a worksheet on integers and scientific facts. Next, you will extend your knowledge by searching on the web for additional scientific facts similar to the ones from the worksheet. Lastly, you will use the facts you gathered to create original problems for your own worksheet. These tasks will require a computer, access to the web, paper and pencil.
