Product Details

Oh, no! Labels have been removed from the kitchen containers at a luncheonette. There are four white solids—they all look alike, but are they the same? Students must use the scientific method and their knowledge of physical and chemical properties to solve the mystery. Students learn about chemical reactions, indicators, melting point and solubility as they help the luncheonette owner reopen for business. This kitchen chemistry demonstration kit is a fun way to introduce basic chemical concepts and to develop students’ problem-solving skills.

Concepts: Chemical reactions, solubility, acids and bases, density, melting point.
Time Required: 25 minutes

Performance Expectations

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.
