ENVIRONMENTAL SCIENCE

RECYCLABLE PLASTICS:
IDENTIFICATION USING RELATIVE
DENSITY AND FLAMMABILITY
Kit #704
Besides having students identify polymers, this lab activity
can be used as an enrichment unit on density .
Students use specially designed trays to identify recyclable
plastics by determining their relative density . They also
test the flammability of the plastics and their physical
characteristics . Students attempt to identify unknown plastics
using the information they have collected .
Accommodates two classes, each with 8 groups of four students.

MAKING AND MODELING
POLYMERS

Kit #706S — Developed by SEPUP
Every day, students use numerous products made of plastic .
This kit introduces the structures and properties of the polymer
molecules that make up all plastics .
Students first investigate the properties of the linear polymer
found in white glue, and then add a cross-linker to explore the
properties of the resulting cross-linked polymer . They then use
paper clip models to investigate the molecular structures of
monomers, polymers, and cross-linked polymers, and explore how
their structural differences alter the properties of the molecules .
Accommodates one class with 16 groups of two students.

EVOLUTION: EXAMINING FOSSIL
AND DNA EVIDENCE
Kit #903S — Developed by SEPUP
In Activity 1, students investigate how whale fossils provide
a line of evidence in support of the theory of evolution .
Students then apply the theory of natural selection to whale
evolution, using anatomical adaptations to infer the habitats
and lifestyles of extinct species . In Activity 2, students
examine classification from an evolutionary perspective.
They compare DNA sequences from a number of vertebrates
and create an evolutionary tree .
Accommodates unlimited classes, each with 12 groups
of two students.
