Syringes and pipettes
Use separate syringes for measurements such as 1ml, 5ml, 10ml
or 20ml. Syringes with plungers can have notches marked on them
using a sharp Stanley knife or scalpel.
You can buy accurately calibrated auto-pipettes that can be set to
reliably deliver volumes of liquid accurate to 1 per cent particularly good for pupils whose manual dexterity is poor.
Available from suppliers such as Griffin Education and Philip
Harris.
Measuring cylinders, beakers and test tubes
Marking up the top of the cylinders with bright yellow tape, Day-Glo
orange tape (DL95) or paint makes them much easier to spot and
can reduce breakages.
Beakers, test tubes and measuring cylinders can be marked up
with Tacti-Mark (DL40/40A/40W); a non-toxic liquid that when
applied to a surface dries and hardens within hours of application.
It can be used mark levels on beakers, define the tops of beakers,
etc. Bear in mind that it will melt upon contact with a high heat.
Elastic bands can be useful to show changes of level in a test tube
or measuring cylinder.
Test tube racks, tripod legs and retort stand legs can all also be
rnib.org.uk
painted in bright colours to increase visibility, reduce accidents and
stimulate residual vision
Trays
One tray (or washing up bowl) containing equipment for each pupil
with sight problems, such as scratch-free goggles and much of the
adapted equipment mentioned above and below. This can be kept
in a safe place by the lab technician ready for the pupil to use.
One empty tray with a lip for pupils to work in a defined area,
making equipment easy to locate.
Light detectors
Our audible light detector (DH248) emits a high pitch tone when in
full light and a deep low pitch when in darkness. Light detectors
are useful for detecting colour changes, as in the formation of
precipitates or a bulb going on or off. They are invaluable in light
and shadow work, for detecting the needle on some measuring
instruments and even for reading a cathode ray oscilloscope.
Timers
Invaluable for crucial timings in experiments. We have a range of
easy-to-see, tactile and electronic timers.
Also, you could consider using the widely available stopwatches
that beep at regular intervals (available from shops such as Argos).
rnib.org.uk
Calculators
View our selection of clear print and talking calculators.
There are various calculators based on laptops. Allercalc can be
downloaded and has the facility to make the font any size and
entry can be via the laptop keyboard rather than having to click on
keys on the screen.
Thermometers
Some pupils find alcohol thermometers easier to read (but it is
worth ensuring that the temperature range is suitable for use) these are available in bright red or blue. Alternatively, some digital
thermometers have fairly large displays. Griffin Education produce
one that may be suitable.
Colour detectors
The Colbolt talking colour detector (DH289) detects 12 basic
colours, not including the variations, such as light, very light, dark
and very dark or combination of colours. Bear in mind that as it
measures pigment, it would be useful for independence in, for
example, pH testing experiments, but not in a titration exercise.
rnib.org.uk
The Colorino talking colour detector (DH288) detects up to 150
colours, including shade variations.
Graph paper and embossing film
We have a range of clear print and tactile graph paper and pie
charts.
Alternatively you can make your own using thermoform, minolta or
a computer system and photocopier. There are several websites
which offer free graph paper templates.
Large squared exercise books are available from Philip and Tacey.
Plastic embossing film (LC22/23) (also known as German film) can
be used on a Geometry mat (LC177) and drawn on using an
embossing tool or 'dead' (inkless) ballpoint pen, to create tactile
images.
Bumpons and Wikki Stix
Bumpsons are great tactile markers and are also great for
indicating levels and measurements. They are available in a range
of bright colours and shapes and provide a great contrast.
rnib.org.uk
Useful for so many things, versatile Wikki Stix (LC49/50/115/116)
can bused for plotting graphs, marking the tops of test tubes and
even plotting light rays.
White screen or card
Placing a piece of white card behind any demonstrations reduces
clutter and improves contrast. In addition, the contents of test
tubes etc can often be seen more easily this way and is particularly
useful when reading the scale on a measuring cylinder.
Blue and red food colouring
The addition of bright food colouring to water can make it visible,
yet it is unlikely to affect the outcome of many experiments.
Braille labeller and Dymo tape
The easy to use, hand-held Braille labeller (DL65) can be used to
produce braille labels on Dymo tape (DL31/53/54), without needing
a knowledge of braille. At only 9mm or 12mm wide the tape is ideal
for marking chemicals in bottles, and the clear tape can be stuck
on without obscuring print labels.
rnib.org.uk
Gas or battery powered lighters
These lighters with long handles are much safer that matches and
provide some independence for pupils.
Rulers and tape measures
We have a range of clear print, tactile and talking tape measures
and rulers.
NES Arnold do an enlarged print ruler.
Using the braille science code
Our Using the braille science code publication covers the code
required up to A Level and is laid out in key stages. It has
particular emphasis on layout students will encounter during
exams. The guide can be purchased in clear print (TC21085P)
from our Online Shop or the PDF file can be downloaded free of
charge.
Accessible image books
Our range of curriculum accessible image books are designed to
support pupils studying subjects at Key Stage 4 of the National
Curriculum. The images in these books have been designed to
rnib.org.uk
convey the information as easily as possible, although the subject
matter may be complex. Each coloured clear print and tactile black
and white image has accompanying supportive descriptions in 24point print and contracted braille (grade two). These descriptions
encourage the user to read the image in a structured and logical
way, additional support from a teacher may be required.
There are three biology titles, two chemistry titles and one physics
title.

Library catalogue
The RNIB Library Catalogue contains all titles available from our
National Library Service including Talking Books, braille, giant print
and braille music.
The catalogue can also be found on UnityUK, which is used by
public libraries across the UK. This means that your local library
may have access to UnityUK and can check what's available in
accessible formats on their usual computer system.
Children's librarians
Our children's librarians are available to assist young people,
parents and teachers with enquiries about books and reading.
There are over 4000 titles in braille, giant print (24 point) and
unabridged audio on CD for children and young people. From
contemporary novels to older favourites we have books by authors
rnib.org.uk
such as Stephenie Meyer, Roald Dahl, Jacqueline Wilson, and
Michael Morpurgo to name just a few!
We also stock non-fiction, and although we don't loan text books,
many of our titles do indirectly support the Curriculum. Books can
be sent to home or school.
Contact our children's librarians on 0161 355 2061 or email

Promoting reading as a pleasurable activity
It is important to look for ways of promoting reading as a
pleasurable and worthwhile activity. Reading materials should be
interesting, attractive and clearly laid out.
A pupil should have as much choice as possible over the selection
of personal reading. However, the teacher should use knowledge
of the pupil's abilities and interests in directing that choice to
ensure exposure to a variety of genres and authors.
The Ways of reading leaflet is designed to help you find reading
materials in accessible formats for children of all ages. We also
have guides to finding books for leisure and books for the
classroom.
Individual texts
Pupils should not be expected to share texts with sighted
classmates. They will need their own, possibly modified, copy of
any text being followed.
Use of alternative media
Supplementary audio or video-taped material is invaluable to
enable pupils to cover the expected breadth of texts in the time
available, without compromising curriculum goals of skill
acquisition.
Access to reference books
Research and project work necessitates the use of reference
books and the selection of information from various sources. Pupils
with sight loss may need the help of a support assistant to access
information which they require. However, the assistant should work
under the direction of the pupil who needs to develop the skill of
thinking about headings under which information may be found,
and understanding different ways of classifying information, such
as alphabetically, by subject or by author.
The assistant should not take over the research task but merely
enable the pupil to access the material. When the pupil has
selected the material required, the assistant may give access to
the content by reading it, or by transposing it into an appropriate
rnib.org.uk
medium, in cases where the pupil needs sustained or detailed
access.
Dictionaries and thesauruses
Oxford large print dictionaries are designed to be clear and easyto-use, with exceptionally clear print to make reading easier. The
main font sizes range from 12 to 14 point.
Our Spelling dictionary for beginner writers is designed for new
braille writers studying at Key Stage 1 and early Key Stage 2. Each
word is shown in 18 point print, uncontracted braille (grade 1) and
if applicable, contracted braille (grade 2).
Non-literary texts
Non-literary texts must also be included in a pupil's reading. These
texts generally need to be studied closely, and the pupil is
expected to draw conclusions, compare and contrast, and evaluate
how language is used. Access to such printed material may be
difficult, but the curriculum expectations may often be met through
the use of taped material. An appropriate selection of current
newspaper articles, letters, advertisements etc should be made
available in large print, braille or on tape.
To obtain access to some reference materials, such as library
books, pupils are likely to need the support of a support assistant,
but technological equipment such as CD-ROM or an optical
scanner, or CCTV can be helpful with suitable preparation.
Pictures and graphics
If pictures and graphics are to be used as a stimulus for any
activity, suitable alternatives may need to be found for a blind or
partially sighted pupil.
Our range of accessible image books contain coloured clear print
and tactile black and white images, as well as accompanying
supportive descriptions in 24-point print and contracted braille
(grade two). These descriptions encourage the user to read the
image in a structured and logical way and, if required, enable
sighted assistants to support them.
rnib.org.uk
Oxford Reading Tree
Stages 1 to 9 (Biff, Chip and Kipper stories) of the Oxford Reading
Tree are available in the shared reading format - braille on
interleaved clear plastic sheets, so the pictures and print story can
be read underneath. The 2007 editions onwards have been
produced in both uncontracted braille (grade one) and contracted
braille (grade two) and they include the capital letter sign and the
2004 braille code changes.
The older editions of Stages 1 to 9 are available while stocks last
and have been reduced in price. These are only available in
contracted braille (grade two) and they do not include the capital
letter sign or the 2004 braille code changes.
Stages 10 and 11 are available in single sided contracted braille
(grade 2). Stages 12 to 16 are available in interlined uncontracted
braille (grade 1) or contracted braille (grade 2). The books are
available on A4 sized paper with non-capitalised braille only. They
are not produced as shared reading books like stages 1 to 9.
ClearVision Library also has some of the books available for loan.
For further information contact ClearVision on 020 8789 9575 or
email info@clearvisionproject.org
Recording
Drafting
Increasingly, all pupils are expected to produce written work such
as book reviews on a word-processor, and to draft and re-draft
their compositions before completing a final version. Pupils who
are blind or partially sighted can work in the same way, using
suitable braille or enhanced print technology. Like other pupils,
they may produce creative writing of a higher standard if freed from
the constraints of handwriting.
A digital voice recorder may be ideal for some learners who wish to
record lessons or lectures and make additional notes in an audio
format.
Reading stands and guides
Reading stands encourage good posture by allowing you to raise
the level of a book closer to your eyes. Used in conjunction with
good lighting, reading and writing is made easier and the stands
rnib.org.uk
fold flat when they are not in use.
Reading guides (typoscopes) are designed to reduce glare and
provide a small cut-out section making it easier to focus on a single
line or small section of text.
Writing frames, pens and paper
Using fine or bold line handwriting pens with clear lined writing
paper can help to make writing easier. A writing frame or guide
may help learners who struggle to write in a straight line.
