Archimedes and Density

Creator:

Robin Spoon

School/Organization:

White Plains High School, Calhoun County School System

Overview:

This podcast is an introduction to using displacement to determine the density of an object. Because density is an intrinsic property, it can be used to identify a substance. A follow-up lab should be used so students can apply the ideas introduced.

 SC (9-12) Chemistry 1. Differentiate among pure substances, mixtures, elements, and compounds. Distinguishing between intensive and extensive properties of matter Contrasting properties of metals, nonmetals, and metalloids Distinguishing between homogeneous and heterogeneous forms of matter MA2015 (7) 16. Solve real-world and mathematical problems involving area, volume, and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms. [7-G6] SC2015 (9-12) Physical Science 1. Use the periodic table as a model to predict the relative properties and trends (e.g., reactivity of metals; types of bonds formed, including ionic, covalent, and polar covalent; numbers of bonds formed; reactions with oxygen) of main group elements based on the patterns of valence electrons in atoms. SC2015 (9-12) Chemistry 4. Plan and conduct an investigation to classify properties of matter as intensive (e.g., density, viscosity, specific heat, melting point, boiling point) or extensive (e.g., mass, volume, heat) and demonstrate how intensive properties can be used to identify a compound.
