Product Details

Big Idea 2

Watch students’ engagement in this exciting guided-inquiry chemical bonding and intermolecular forces activity! Solidify student understanding with the quick Splatter Test demonstration and get the thought process ball rolling. Students complete a homework assignment and create their very own schematic flow chart as part of their procedure for lab day. The wet lab portion may be done in one 50-minute class period. The identity of four unknown solids are determined, based on bond type, and beautiful dyed fabric colors are observed and identified based on bonding and intermolecular forces. The homework reinforces the prerequisite knowledge needed for lab day, and the hands-on activity helps build enduring understanding.

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.
