ENVIRONMENTAL SCIENCE

DECOMPOSITION
Kit #35

What do the terms “biodegradeable” and “decomposition” mean,
and how do they happen? These are just two of the questions
explored in this activity and are both important concepts in the
study of life cycles . Students investigate the effect of various
factors on decomposition and biodegradability .
Students use an inquiry method to set up a series of experiments
which focus on determining the rate of decomposition, the
effect of soil type on decomposition, and the different types of
substances which decompose .
Accommodates four classes, each with 12 groups of two students.

ORGANISMS AS INDICATORS
OF ECOSYSTEM HEALTH

Kit #555S — Developed by SEPUP
Students examine simulated samples of aquatic
macroinvertebrates from the same river collected at three
different points in time . They calculate the relative proportion
of macroinvertebrates that are intolerant to pollution
compared with the total catch . These proportions are an
indicator of water quality . They then identify patterns in the
data and construct arguments for possible cause-and-effect
relationships .

Accommodates unlimited classes, each with 8 groups of students.

ENGINEERING & DESIGN: MODELING
AND MITIGATING STREAM PROCESSES
Kit #446S — Developed by SEPUP
Students model the phenomenon of sediment movement in a river
using a unique mini stream table that provides evidence for how
geoscience processes change Earth’s surface . In Part A, students
investigate how the changing energy of flowing water erodes and
deposits sediments to create common landforms . Part B is an
engineering design challenge where students use design criteria
and constraints to design and test erosion-control structures . Based
on the results of their initial testing, students redesign and retest
their structures .
Accommodates two to three classes, each with 8 groups of 4
students.
