List of equipment for science curriculum development
Bezel
Sautoir
List 1 Equipment lists
List 1 = Equipment for introduction to science in primary and junior secondary classes where there may be no laboratory and the teacher may not be a trained science teacher
List 1A Equipment for physics, chemistry, biology, and earth sciences
List 1B Consumables
List 1C Tools
List 1D Personal protective equipment, Safety face shield, Safety glasses, Safety gloves, Safety apron

List 2 = Equipment for middle secondary school which may be added to List 1 and which has a laboratory which has electricity, gas and tap water. The teacher is a trained science teacher but not necessarily a subject specialist of physics or chemistry or biology. Bunsen burner and microscope are used for demonstrations by the teacher
List 2AA Locally available chemicals and substances, common name first, chemicals for teaching physics, chemistry, biology, and earth sciences
List 2A Locally available chemicals and substances, chemical name first
Hazard
List 2B Chemicals and substances which can be supplied by companies which export to educational institutions, and are not usually available locally.
(List 2A + List 2B) All the chemicals and substances, if all items had to be imported
List 2C Chemicals and substances which can be supplied by companies which export to educational institutions, or may be available locally,
which are NOT needed for junior secondary science teaching
List 2D Hazardous chemicals, chemicals with information about hazard or expense which are are NOT recommended for use in junior secondary science classes

List 3 = Equipment for advanced secondary science classes up to and beyond school leaving standard, in fully equipped laboratory, taught by fully trained physics or chemistry or biology teacher and where quantitative experiments are done by students in groups.
List 3A Live materials used for biology teaching
List 3B Materials for teaching experiments in UNESCO "Document Series 39 Teaching Biotechnology in schools"

Categories
Item = Item description abbreviated from catalogues
Source = Source of supply of the item in its least expensive form and at a level of technology appropriate to junior secondary science teaching. This source classification is based upon the experience of UNESCO with supply from international or local supply sources, and the construction of low cost science teaching equipment.
Local purchase = Item which is commonly available and is normally sold for purposes other than science education, e.g. bicycle pump, jelly crystals, salt, fishing sinkers. The estimated cost quoted is based on catalogue prices from international suppliers of science equipment.
Local manufacture = Item which can be made up commercially in local workshops using basic tools and commonly available materials. The estimated cost quoted is based on catalogue prices from international suppliers of science equipment.
Low Cost = Item which can replace the locally fabricated or imported item. List 1 has a simple design and can be made by the teacher or students at no cost or at the cost of simple materials, e.g. "Aspirator polythene 1000 cm³" could be replaced by a 1 litre plastic drink bottle. Some items can be found in discarded equipment, e.g. ball bearings. The estimated cost quoted is based on catalogue prices from international suppliers of science equipment.
Catalogue = Catalogue item from international suppliers of science equipment. This item is usually obtained from local agents or is directly imported.
Class = Class of 40 students working in 5 groups.
Estimated costs of unit or individual item should be included to facilitate first level budgetary planning and to allow for preliminary calculation of costs for one class and total costs. Actual costs can be obtained only from quotations from local agents and international suppliers, which will take into account the volume of the order, destination of the consignment and packaging needs and customs and storage charges. Estimated costs should be quoted in United States Dollars, ex-works, export packed and based on an average of costs from catalogues.

The chemical names at the left margin follow the system in "Chemical Nomenclature, Symbols, and Terminology" published by the Association for Science Education, UK Other names are either the List 1 IUPAC name, if it is different, or a name in common usage, or the name of a similar substance, or the name of a mineral containing the chemical. HAZARD details are based upon information from 1991 catalogues and chemical names are taken from these catalogues.

Hazard
EXP: can explode due to flame, shock or friction.
OXD: can react with substances to produce great heat.
FLAM: can readily burn or catch fire.
TOX: severe of poisoning risk if absorbed.
HARM: some health risk if absorbed.
COR: can destroy living tissue on contact.
