FLAME TESTS AND EMISSION
SPECTROSCOPY
Kit #111
The concept of spectrum analysis is introduced with this Lab-Aids kit .
Bunsen Burners are all you need to enable students to conduct these
dramatically colorful, spectroscopy experiments .
Students spray fine mists of water-based solutions, which contain
various amounts of salts, into a Bunsen burner flame. They first
observe the color that various metallic elements impart to a Bunsen
flame. Then, the students view the flame through a spectroscope and
observe the spectra of each of the elements that are visible to the
human eye .
Accommodates two classes, each with 12 groups of two students.

SOLID ALCOHOL AND ESTERIFICATION

Kit #113
In this kit, students synthesize chemical substances that are normally
found in nature . The four lab activities create a bridge from organic
chemical concepts to their practical applications .
Students first make their own heating “unit.” A solid alcohol is
ignited to provide energy for synthesizing three different esters,
Ethyl acetate, Methyl salicylate (oil of winter green) and Amyl
acetate (banana oil) . Students are asked to describe the odor and
color of each ester . In the last part of this activity, they create a
molecular model of ethyl acetate using Lab-Aids molecular model
®
parts . Each student saturates his worksheet with samples produced
(oil of wintergreen and banana oil) from the experiment .
Accommodates two classes, each with 12 groups of two students.

DENSITY: LAYERS OF LIQUIDS
Kit #114
This activity provides students with experiences that allow them
to develop an operational definition of density. Students are
provided with liquids of different viscosity and density and asked
to observe and predict, based on their observations, the relative
density of each . They then test their predictions and develop an
understanding of density by preparing sequences of liquid layers .
They are given values for the density of each liquid and asked to
use this information to estimate the density of an unknown solid .
Finally, there is an optional challenge to design and carry out an
experiment to determine the density of a fourth liquid .
Accommodates two classes, each with 6 groups of four students.
