Product Details

General, Organic and Biological Chemistry What better way to understand the concept of density than by using scientific observations, patterns and trends to determine relationships among variables? Students determine the density of two “mystery metals” by plotting mass and volume measurements and then analyzing the precision and accuracy of their data. Students feel like accomplished scientists discovering the concept of density for themselves just as Archimedes did with a crown many centuries ago. Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
