Plain English in science
4(2) Fume cupboards
The Department of Education and Science (DES) has recently issued ‘Design Note Number 29 – Fume Cupboards in Schools’.
4(2) Air-rifle hazard
Example of a potentially hazardous use of an air rifle.
5(3) Bell jar implosion
A near-miss in an experiment involving the evacuation of a bell jar.
5(3) Another near miss
A close shave during the disposal of an old sample of phosphorus pentachloride.
5(3) ‘Blazing goggles’
A potential danger when goggles are being used by younger pupils.
6(4) Safety in school science’ articles
ASE publishes a collection in one volume of the articles which have appeared in “Education in Science” over the last four years.
6(4) Pulse rate measurement
In certain circumstances an aid to rapid, reasonably accurate pulse measurement could be very useful.
8(6) Petrol/oxygen explosion
We first described a safe method for such a demonstration in Bulletin 22. Work for a trial school has given rise to the simpler, more convenient set up.
8(6) Silver nitrate
Because of recent high price levels for silver nitrate the reduction of the costs of using this compound has become a topical subject.
10(8) Microburettes
By far the greatest expenditure on silver nitrate falls in titrations for CSYS work. The feasibility of reducing the scale of these operations by the use of much smaller burettes was thus closely examined.
12910) Titration curves
Some experiments lend themselves readily to interfacing, others may not. We seek here merely to illustrate some of the general features of experimental work that may make rewarding the insertion of a computer into the experimental system, using titrations as an example.

4(2) Air-guns again
Following the publication of a note of the hazards of using air-rifles in the lab. we have been sent an idea on remote firing which, it is suggested, might further reduce the hazards.

7(5) Marine aquaria
Our response to enquiries on setting up and maintaining marine aquaria.
10(8) Tidal aquarium
Our original design for a tidal aquarium appeared in Bulletin 6 The original constructional details were for glass tanks and used siphon bottles etc. Since then we have refined and changed the design several times and have decided to publish an updated version.
12(10) Experimental errors – the measurement of g
Following on from the article on computer controlled experiments in Bulletin 132, we have picked out one for further discussion here, the measurement of g.
17(15) Constant current supply
We usually expect power supplies to be constant voltage devices, ignoring the effect of internal resistance.
