Product Details

Nothing catches students’ interest like catching a criminal! The window is broken and the television is missing! Luckily for student investigators the burglar left something behind—fibers from his or her clothing that got caught in the broken glass. Students eagerly take the samples back to the crime lab to be analyzed. Six different types of fibers are examined using a burn test and dye analysis to discover their unique physical and chemical properties and determine the identity of each. This kit includes all the necessary materials, complete Teacher Notes and an optional microscope extension activity. Complete for 30 students working in pairs.

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-PS1-2. 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.
