Jim Hebden's Chemistry Resources
A Note From Jim Hebden:
The accompanying files are being donated to
the Chemistry teachers of British Columbia as a “thank you” for the
support they have given me during my teaching career. I have scoured
the available literature for several years to find good, reliable
and USABLE demonstrations that illustrate Chemistry concepts in a
clear manner and have used most of the demonstrations for several
years to help maintain a high level of interest in students. I hope
the material in the files proves useful.
should always be tested ahead of time to make sure you can make them
work properly. Some chemicals should only be used by properly
trained teachers because of the potential hazard involved when
improperly used by untrained individuals. I have tried to include
only demonstrations that are safe according to the available
literature and cannot be responsible for an unanticipated and
hurtful outcome. Teachers using the demonstrations should read over
the preparation and procedure thoroughly and must assume any risks
resulting from their decision to attempt the demonstration. If
possible, the original books quoted should be consulted.
This document lists all the Chem 11, Chem 12 and General
demonstrations by course, topic and title.
This document gives a procedure for removal of toxic cations from
solutions destined for disposal.
Chem Resource Books.pdf
This document gives a listing of general print resources that should
probably be available to every Chemistry teacher, two outstanding
sources of specialized equipment and 25 books of demonstrations. The
books of demonstrations have been given my evaluation of their
usefulness, the price and where they can be ordered.
Chem Teaching Strategies.pdf
Teaching tips and strategies for Chem 11 and 12, including a few
tips for labs, demonstrations and equipment purchase and usage.
storage and disposal.doc - NEW 2009
Storage and disposal codes for common (and some
not-so-common) chemicals. This list probably contains most chemicals
found in BC high schools. Disposal codes are at the end of the
document. With slight modification, the document can serve to keep
track of available chemical inventory
This document lists the compositions of Canadian coins. This
information is useful for teachers wishing to create a lab based on
analyzing Canadian currency.
Crystal Growing Manual.doc - NEW 2009
Gives instructions for students (and teachers) who
want to grow crystals.
Detailed Study Points.pdf
This document is intended for student use and lists every point that
a student in Chemistry 11 and Chemistry 12 should know. This is a
most useful checklist of essential required knowledge.
This document was presented at an inservice day to encourage
elementary school teachers to do more “hands on” chemistry and
includes 12 simple but engaging experiments which can be done with
commonly available materials. Each experiment’s description includes
how to perform the experiment, an explanation of what is happening
and some suggested extensions for further investigation. Many
elementary school teachers are not comfortable with chemistry
experiments and hence the explanations are complete enough to let
elementary teachers feel confident in explaining what is happening.
This document was co-written with Keith Chambers, an elementary
teacher of vast experience.
Fancy Crystals.doc - NEW 2009
Gives instructions for growing a two-layered
crystal: pale purple chrome alum in the center and a layer of
colourless potassium alum outside. Gives a stunning result!
Fit of Demos to Curriculum.pdf
This document shows exactly where in Chem 11 and Chem 12 each
demonstration fits. The individual topics follow the subheadings in
Hebden: Chemistry 11 (and 12), A Workbook for Students.
This document is a forensics lab that requires students to undertake
a forensic analysis on white powders and test them for
pseudo-cocaine, pseudo-heroin, etc. The student is placed in the
role of a “forensics technician-in-training” and requires an
official report of results when finished. This lab can be used in
grades 9-12. Warning: this lab requires a substantial amount of
setup and may not be suitable if a lab assistant is not available,
although most of the chemicals will last from year-to- year and are
used in small amounts.
This document gives the preparation instructions for the reagents
used, and the unknowns.
This document gives 40 demonstrations that can be used “when the
mood hits” to enliven a Chemistry or general science class. Many of
the demonstrations make wonderful contributions to a Chemistry Magic
Chemicals.doc - NEW 2009
This document was prepared for SD #73 so as to
address concerns as to which hazardous chemicals should be permitted
to be used by teachers and students in the District and the
guidelines under which usage is permitted.
Lab Aide Training.pdf
For those teachers fortunate enough to have a lab assistant, this is
a training document for new lab assistants. Teachers who have
less-than-optimal training in chemical handling may also find this
document useful. (Let’s face it, not every Chemistry teacher has a
degree in Chemistry.)
report check list.doc - NEW 2009
A quick check list for students to make sure that
their lab reports are properly presented
slip for students.doc - NEW 2009
This is a quick-to-use slip of paper that a teacher
hands out to students who are late getting out of a class, test or
lab. Very useful.
This document describes how to prepare buffers in the range pH 3 to
silver.doc - NEW 2009
Gives instructions for reclaiming and recycling
silver wastes, minimizing lab costs and enabling continued use of an
otherwise expensive chemical.
This document is intended for student use and describes how to make
up an outstanding set of Chemistry study notes.
Testing for Peroxides.pdf
Several organic liquids can form hazardous peroxides that can
detonate with staggering impact. This document gives a simple
procedure for quickly testing whether an organic liquid contains
sufficient concentrations of peroxides to warrant immediate
disposal. This procedure should be done once a year unless you want
to risk a highly hazardous situation!
Typical Magic Show.pdf
This document gives instructions for putting on a Chemistry Magic
Show, including equipment needed, how to prepare the required
solutions, how to perform each demonstration and an explanation of
what is happening with each demonstration.
Universal Indicator prep.doc - NEW 2009
Gives instructions for making a good universal
