Mass and Volume

For lesson 4, we will explore the concepts of mass and volume.  We will briefly discuss the ChemCatalyst from the Lesson 4 PowerPoint and students will be reintroduced to the metric system.  To help reinforce the learning, we will embrace the power that is Pete Hendley:

We will discuss common metric system prefixes and learn the difference between milli- (1/1000), centi- (1/100), and kilo- (1000) as applied to the base units of meter, liter, and gram.  For the remainder of the lesson, students will work with a partner to complete Activity A for both the Triple Beam Balance and Measuring Volume Gizmos on the Explore Learning website.
