Chemistry Experiments with the Flame Tube

// Tuesday, May 26, 2020 • Tom Kuntzleman

A Flame Tube, also known as a Ruben’s Tube, is a classic physics experiment that provides a spectacular visual demonstration of sound waves.¹ To make a Ruben’s Tube, a bunch of tiny holes are drilled in a line about 1 cm apart along one side of a steel pipe (Figure 1).

An advantage to teaching on the trimester schedule allows me the opportunity to teach the same course again roughly twelve weeks later.

Writing Conversion Factors

This worksheet is intended to be used as a "Guided Instructional Activity" (GIA). Students read a statement that gives a either a conversion factor or a pair of related measures and then write the information as two equivalent fractions ("conversion factors") and as an equality.

Finding and Writing the Molar Mass of Elements

// Tuesday, November 4, 2014 • David Licata

This worksheet is intended to be used as a "Guided Instructional Activity" (GIA). It asks students to find the molar mass of selected elements and write the molar mass as two equivalent fractions ("conversion factors") and as an equality. In each representation, students are forced to give the numeral of the measure, unit, and identity of the chemical.
