This unit re-introduces students to the metric system and its base units and prefixes in a context that emphasizes language and the quantitative data sets they will encounter in science texts.

Students learn how to convert units within the decimal-based system as well as learn the abbreviations used in texts and lab instructions. They apply their understanding of the  metric system in a measurement activity. Additionally, the unit introduces the scientific concept of displacement, and students measure the volume of an irregular shape by using this concept.
