MARKING SCHEMES
SUMMER 2007
DESIGN AND TECHNOLOGY
INTRODUCTION
The marking schemes which follow were those used by the WJEC for the 2007 examination
in GCSE Design and Technology. They were finalised after detailed discussion at examiners'
conferences by all the examiners involved in the assessment. The conferences were held
shortly after the papers were taken so that reference could be made to the full range of
candidates' responses, with photocopied scripts forming the basis of discussion. The aim of
the conferences was to ensure that the marking schemes were interpreted and applied in the
same way by all examiners.
It is hoped that this information will be of assistance to centres but it is recognised at the
same time that, without the benefit of participation in the examiners' conferences, teachers
may have different views on certain matters of detail or interpretation.
The WJEC regrets that it cannot enter into any discussion or correspondence about these
marking schemes.

method. Give one mark for each correct fact about the
named method. Just three examples are given below but
others are acceptable see note.
Canning
Bacteria are deprived of air [1] so they cannot multiply and
cause decay or poisoning [1];
Bacteria are destroyed / killed if the food is heated to a
very high temperature [1] so they cannot multiply and
cause decay or poisoning[1];
Bacteria cannot multiply [1] in high acid, salt or sugar
liquids [1] and cause decay or poisoning[1]. Micro
organisms require an optimum pH [1] to sufficiently
reproduce / multiply to cause food poisoning [1].
Too acidic. Too salty / sugary. No air.
Freezing
Bacteria cannot multiply [1] and cause decay or poisoning
because the freezing temperature -18/ 32C [1] makes
them dormant / inactive [1].
Too cold.
Vacuum Packing
Bacteria are deprived of air [1] so they cannot multiply [1]
and cause decay or poisoning[1].
No air.
Dehydration/drying
Bacteria are deprived of water/moisture [1] so they cannot

Defrosting: Make sure that the chickens are thoroughly
defrosted before cooking [1]. Parts inside the chicken that
are still frozen when in the oven will be slower to reach the
maximum cooking temperature [1] and could allow
bacteria to multiply [1].
Cooking: Use a temperature probe [1] to check that the
internal temperature is correct for ensuring complete
cooking to destroy bacteria [1].
Check oven temp
Hot holding: Monitor the temperature [1] that the chickens
are displayed at to make sure no bacteria develop if the

Calculate the resultant force at the tow ball and note if it exceeds 50 newtons.
[5 marks]
Listing ACWM and CWM gains 1 mark
ACWM 500 x 1, Towball x 2.5
CWM 500 x 1.2
Forming this equation gains 1 mark
CWM = ACWM
500 x 1.2 = (500 x 1) + (TB x 2.5)
600 = 500 + 2.5TB
Calculating the correct value for TB gains 3 marks
TB = (600-500)/2.5
TB = 40 newtons
An actual statement is not needed for full marks if the answer of 40
newtons is correct.
A correct statement can be given 1 mark if the preceding calculation is
not strickly correct.
Therefore downforce on tow bar is within limits or does not exceed 50
newtons.
Award marks relating to the stage reached.

A seaside town has a problem with pollution on the sand beach. A great deal of debris
is washed up with each tide and when people visit the beach some drop litter that must
be cleared up by hand.
The local authority would like your help to design a quicker method of removing the
rubbish and things that are washed up onto the beach. They suggest something that
could be pulled behind a tractor or similar vehicle.

Explain what can be done to improve this:
[2]
Use Galvanised / stainless steel / brass screws to prevent rusting. 2
marks
Fault 2: The bench is uncomfortable to sit on:
Using notes and sketches, explain what can be done to improve this.
[4]
Improvement: Make the slats more ergonomic for the user and perhaps
add a back to the design.
2 marks
Add more slats.
2 marks
Supportive diagrams.
2 marks
Fault 3: The bench is not stable or rigid when you sit on it.
[4]
