Abstract
Objectives:
Students will be able to explain and give examples of both parts per million and parts per billion. In the next activity students will use these values in the analysis of air quality data.
National Science Education Standards:
Earth materials are solid rocks and soils, water, and the gases of the atmosphere. The varied materials have different physical and chemical properties, which make them useful in different ways, for example, as building materials, as sources of fuel, or for growing the plants we use as food. Earth materials provide many of the resources that humans use.
Scientific investigations involve asking and answering a question and comparing the answer with what scientists already know about the world.
Scientists develop explanations using observations (evidence) and what they already know about the world (scientific knowledge). Good explanations are based on evidence from investigations.
