Quality of Water Test Kit
Conduct qualitative tests on samples of water from
various sources and identify pH, dissolved oxygen, odor,
colour, turbidity, and coliform bacteria. Students also
learn to distinguish between ground, surface, drinking,
and waste water. Includes: enough materials to complete
six water quality tests, teacher’s guide, and reproducible
student worksheet. Grades 6—12.
For 10 students.
For 24 students.

Electrochemical Remediation
of Wastewater
Water pollution is one of the largest threats facing
the global population. Water is a finite resource. Once
polluted, it cannot be set aside in the hopes that the
environment will “make” new, clean water. Recently, a
great deal of attention has been given to less traditional
alternatives to the typical process of coagulation/flocculation.
One such approach receiving a good
deal of attention is a process called electrocoagulation.
Electrocoagulation is a coagulation process carried out
by an electrical charge.

Detergents and the Environment
Understand the consequences of cultural nutrient
overloading on the aquatic environment. Demonstrate
and monitor the effects of two detergent builders on
natural water samples. Visually quantify the differences
between phosphate and non-phosphate detergent
builders on aquatic organisms.
1323M — $43.95
The Production of Biodiesel
In this activity, students will be performing a twophase
process to produce small batches of crude
biodiesel. The crude biodiesel produced is of sufficient
quality for use in the demonstration of the burning
qualities of both biodiesel and vegetable oil. Included
is an optional small-scale exercise where the students
will use a washing procedure for the crude biodiesel.
1319M — $53.95
Water Treatment and Filtration
Students will develop a knowledge of the processes
performed at a water treatment plant and understand
the reasons for each process. They will perform, on a
small-scale, several of the procedures that occur in a
water treatment plant on “polluted” water. They will
examine the changes in the water after each treatment
step is performed.
SB45473M — $64.00
Cleaning Up Oil Spills with Oil-Hungry
Bacteria Lab
Model various oil spill scenarios and monitor the effectiveness of
the provided freeze-dried, oil-degrading microbe mixture in remediating
the waste. Students set up a simulated oil spill in water and treat it
with the microbial product to observe the physical changes and degradation
of the oil film over time. Additionally, students simulate three spill scenarios on
beach sand, gravel, and cobbles to observe the difference in degradation rates.
The class will also explore bioremediation methods for other waste chemicals
and compare their effectiveness to traditional clean-up methods. Materials for
40 students. Grades 7-10. Sh. wt. 7 lbs.
SB48359M— $95.15
Refill Kit. Sh. wt. 1.25 lbs.
SB48360M — $33.30
Bioremediation by Oil Eating Bacteria
The naturally occurring process of biodegradation can be
enhanced by bioremediation to minimize the catastrophic
effects of oil spills. Students grow a mixture of oil eating
bacteria and demonstrate how the enzymes produced by
these microbes digest hydrocarbon molecules, causing
degradation. Includes: instructions, background information,
study questions, oil-eating bacteria pellets, growth
medium, and pipets. Grades 6—12. Sh. wt. 0.63 kgs.

Using Chemical Reactions to Reduce Waste
Students learn that wastes from many industrial processes
contain toxic or valuable substances that can sometimes
be reclaimed then recycled or disposed of safely. Working
in groups, students reclaim copper from a liquid “waste”
containing dissolved copper chloride. They measure the
effectiveness of three different metal replacement reactions
at removing the copper from the “waste.” They then
compare the effectiveness, cost, and safety information for
each replacement reaction and decide which metal would
be the best to use for removing the copper from the “waste.”
Designed for six groups of 4 or 5. Grades 6—12. Sh. wt. 3 lbs.
