PROTOTYPING BOARDS
5 P ROTOTYPING BOARD
This Prototyping Board, also known as ‘Breadboard’, is ideal for making up 5 P ROTOTYPING BOARD
electronic circuits or test circuits without the need for soldering, as wires and
components can be simply pushed in or pulled out again. This makes it ideal
for designing circuits or when components need to be changed, and allows
components to be used many times over. Components and wires are held
in place by clips below the holes, the clips being interconnected in groups to
create connections between components.
Made from white high durability Acetal board mounted on an adhesive foam
base, the contact positions are clearly indicated by screen printed alphanumeric
grids and colour coded polarity indicators. The boards are also interlocking,
enabling two or more boards to be fixed together. There are a total of 400 tie

and an improved specification and can be used with or without a computer. 3 MAINS POWER/JOULE METER
BEST
Designed to be simple enough to use at KS3, and flexible enough for more
advanced use at KS4 and beyond, the Joulemeter simply requires an input SELLER
supply and a load to be plugged in (e.g. a solar panel and a motor) and the
meter will display the values of the power and the energy transferred. For
simplicity, the instrument automatically adjusts the display to show suitable
units and an appropriate number of decimal places, so that it can deal with
a very wide range of values (e.g. for energy, from 100 nanojoules up to
1.75 megajoules).
This version of the Joulemeter functions almost identically to the previous
version but in addition the meter also keeps a log at the chosen sample rate
when the total energy transferred is being measured; the data can then be
loaded on to a PC using free mini-datalogger software. The function button
allows any of four settings to be selected for the required quantity to be
measured (energy and time; power; average power; voltage, current and
power).
Please Note: The new version is suitable for use with immersion heaters
(HE18720), but the old version is not.

(Safety /Separated Extra Low-Voltage) classed, which means that no part of the
system is at more than 50 volts - which means it is very safe and suitable for
student use. The system allows the user to compare electrical transmission at
low and high voltages and the results are displayed by the brightness of the two
on-board MES lamps.

transmission of electricity? SELLER
The National Grid Simulation Kit
simply and safely demonstrates
the advantages of high
voltage transmission, and the
disadvantages of low voltage
transmission. Two clear boxes with
viewable step-up and step-down
transformers are connected, and
by gripping the insulated cable that
connects them, the wasted energy
can be felt in the form of heat.

1 B RIDGE RECTIFIER
1 BRIDGE RECTIFIER
This convenient and useful apparatus transforms alternating current (AC) into
direct current (DC) using diodes in a specific arrangement. The Bridge Rectifier
consists of four diodes connected in a bridge circuit, which allows AC current
to be input into the circuit and, by full wave rectification, DC current will be
output. The unit has a circuit diagram printed on the top so that students may
gain an understanding of the importance of diodes and how they can rectify
alternating current to direct current. Weight: 0.2kg. Dimensions (L x W x H):
150 x 100 x 100mm.

liquids of their choice (not supplied). The kit comes with 6 specially designed 6 DARK AND CLEAR
containers and a number of clips and cages to hold the materials in place. In
addition the kit comes with a quantity of metal, card and bio-degradable plastic GROW BELL
samples to experiment with, and a project work book is provided. Pupils should be A
encouraged to bring their own materials to conduct experiments and observe the B
amount, and rate of degradation over time, in differing materials and liquids.
The BioDegradability Kit has been designed to support the teaching of
Geography and Science within the National Curriculum framework and

A
This innovative composter allows students to clearly observe how the
composting process works. Pupils can discover, through scientific enquiry, C
methods of composting and its potential to reduce the impact on climate
change, whilst benefiting the world’s fragile eco systems and promoting
recycling and sustainability. The composter can be used to discover and
demonstrate how everyday waste, including uncooked vegetable peelings,
garden cuttings and any suitable kitchen scraps, when properly composted can
provide an excellent fertilizer for organic gardening and free nutrients for the
soil. The transparent containers allow students to view the gradual composting
process and observe the changes in colour and texture that occur. In addition,
the drop in level of waste materials and the increase in volume of liquid can
be observed and measured. The pupils will be able to conduct experiments
to investigate the process of how micro-organisms break down the contents,
compare the impact of different levels of light and temperature or try different
combinations of waste matter to analyse the quality of the compost produced.
The composter includes 4 specially designed transparent containers with carry
handles, 4 inner liners complete with drainage holes, 4 lids with lifters and a
comprehensive teacher guide.

FORENSIC SCIENCE BLOOD ANALYSIS
1 T HE MYSTERY OF THE BLOOD STAIN 1 T HE MYSTERY OF THE BLOOD STAIN
Learn how blood stains can be used to solve crimes. Students will become
forensic scientists as they try to solve a murder using a “bloody stain” left at the
scene of the crime using simulated Neo/BLOOD®. First, they’ll identify whether
or not the stain is actual blood by searching for simulated blood cells under the
microscope. Then they’ll solve the crime by performing ABO and Rh typing of the
stain as well as of samples from the victim and several suspects. The match will
help them “nab” the perpetrator! As a result, the students will learn about blood
groups, blood typing and how blood stains can be used in solving crimes.

3 FORENSIC CHEMISTRY OF BLOOD TYPES
2 BLOOD TEST KIT 3 F ORENSIC CHEMISTRY Blood typing is a method of classifying blood based on the presence or
OF BLOOD TYPES absence of specific proteins (erythrocytes), on the surface of red blood cells.
Blood type, an inherited characteristic, is valuable to know in that it affects
medical procedures, such as surgery and transfusions, paternity testing, as well
as serving as evidence in criminal investigations. Determining blood type can
help provide supporting evidence or eliminate a possible suspect’s involvement
in a crime. This activity includes a teachers manual and student guide and
analysis copy-masters. There is enough material for 15 groups.
Note: This activity uses Innovating Science Simulated Blood and is safe for
classroom use.

4 CHEMILUMINESCENCE IN BLOOD
Crime scene investigators examine the scene of a possible violent crime for
evidence, such as fingerprints, hair, fibre, etc. After collecting the evidence, they
notice there is no visible blood. Someone sprays the area with a liquid then
turns out the lights. A strange, faint glow appears in certain areas of the scene.

Fluorescent fingerprint powder is used in conjunction with an alternative light
source (i.e. lasers and low powered ultraviolet lamps). It allows the visualisation
of latent prints which otherwise may go undetected when using conventional
processes. Suitable for either rough or contaminated surfaces or multi coloured
surfaces where it may not be possible to choose a conventional powder which
separates the latent print from its background. Easily applied with a soft brush,
this powder fluoresces at slightly different wavelengths to provide a choice
when dealing with problematic backgrounds.
