ENVIRONMENTAL SCIENCE

IDENTIFICATION OF SUBSTANCES
Kit #83
In this kit, students are asked to identify common metallic
and non-metallic ions. Through this identification process,
they learn that each substance has distinctive properties . As
a closing activity, students conduct chemical tests on four
unknown substances . All test results are safe, clear, colorful,
and unmistakable!
Accommodates three 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 the relative density of each based on their
observations . 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.
