Product Details

Imagine life without your favorite electronic devices! Use this guided-inquiry lab activity to investigate the essential function of resistors in modern electronics. In this two-part “mystery” analysis, students first decode the color bands on a series of nine unidentified resistors to predict their resistance values. They then test their predictions by placing the resistors in series and parallel circuit combinations and measure the current and voltage. Students see how resistors help control the current to circuit components and split voltage to bring power to multiple components. Versatile and very affordable activity connects concepts and applications and will fit in any electricity unit. Super Value Kit is complete for 15 student groups. All materials are reusable!

Performance Expectations

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.
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.
