ASSESSMENT

General Points:
• The artefact made by the student should display the range of skills and
complexity to match their abilities.
• The project must be made in school under the supervision of the teacher
• Ensure there is a balance time provision for the development of
artefact, folio and experimentation
• Encourage students to explore a wide variety of project topics and types
• Students should develop their folio in tandem with their artefact
• Where there is a need for a student to do some investigative work in an out-
of-school setting or to acquire a specialised component/process in order to
complete the coursework, this must be done with the prior approval of the
teacher


COURSEWORK

EY4106

BUILDING SCIENCE AND EXPERIMENTATION


EY4106
EXPERIMENT 1
Experiment: To show the slump of concrete
• Equipment: standard hollow slump, tamping rod, meter stick, measuring
tape.
Method
1. Place the cone on a flat surface.
2. Fill four equal layers, tamping in between each layer with a rod.
3. Carefully lift off the cone.
4. Place the meter stick on top of the cone.
5. Measure the distance from the stick to the concrete, this is the slump.

Results (Please use results from your own experiment!)
Sample A=, Sample B=, Sample C=
Conclusion
• The slump test is used to compare the consistency of mixes made of similar
materials in the same proportion. If the slump varies it can be a warning that
the composition of the concrete has been altered. It will not show what
changes have occurred but can be used as a warning.
• For the samples tested it is obvious that the greater the amount of water
used in the mix, the greater theofslump valueTechnology also shows the

EY4106
EXPERIMENT 2
Experiment: To show the amount of silt in a single batch of sand
• Equipment: sand, 1000ml measuring cylinder, salt, water.
Method
1. Pour 150ml of salt water into the cylinder.
2. Add sand until the water level reaches the 300ml mark.
3. More salt is added to bring the level up to the 500ml mark.
4. Cover the top and shake vigorously.
5. Leave to settle for three hours.
6. Measure volume of silt and volume of sand.
Result [Calculate as]
Calculate = Height of Silt x 100 = % Silt
Height of Sand 1
(Use your own experiment results!)
Conclusion
• Silt in the concrete prevents cement and aggregates bonding together,
resulting in weak concrete.
• 8% or less of silt in acceptable, anything higher than this and the cement will
not bond fully with the aggregate.

EY4106
EXPERIMENT 3
Experiment: To test for bulking of sand.
• Equipment: flat bottomed cylindrical glass container, water, rod, damp
sand, tray.
Method
1. Place the damp sand into the container and measure the volume. (D)
2. Pour the sand onto the tray.
3. Half fill the container with water.
4. Put the sand into the container and mix using the rod until fully
saturated.
5. Measure the height. (d)
Result [Calculate as]
D – d x 100
d 1
Conclusion
• This experiment shows very clearly that batching by volume can be
very inaccurate, if the sand or aggregates are damp. A miscalculation
of 32% would have an enormous effect on the strength of the
concrete. Department of Design & Manufacturing Technology www.motivatednotes.com

EY4106
EXPERIMENT 3


EY4106
EXPERIMENT 4
Capillary Action Test
Aim:
• To examine the effect of DPC in halting the capillary action in the brick/block work.
• Equipment: basin, four dry bricks, water, strips of DPC sufficiently large to cover a brick.
Method:
1. Place two bricks in the basin and add water until the bricks are half submerged.
2. Cover one of the bricks with a strip of DPC, leave the other bricks uncovered.
3. Place the remaining bricks directly on top of the bricks in the water.
4. Leave the bricks in the water for one week and observe the results.
Results:
• After the bricks had been left in the water for one week the water had soaked up to the
top of the bricks which were partially submerged. Furthermore, the top brick (A) of the
pair without a strip of DPC had become wet at its base while the brick (B) which was
placed over the strip of DPC was still dry.
Conclusion
• This test demonstrates that the water will travel upwards through block/brickwork by
means of the capillary action provided there is sufficient moisture. The results also show
that a strip of DPC completely halts the spread of moisture through brick/block-work, thus
highlighting the importance of including a suitable DPC, in walls, floors, etc., to avoid all
possible problems relating to damp penetration into a building.

EY4106
EXPERIMENT 4


EY4106
EXPERIMENT 5
Experiment: To show capillary action in narrow spaces
• Equipment: two panes of glass, match stick, container, elastic
band, water, food colouring.
Method
1. Fill the container with water.
2. Add the food colouring and mix until the water has changed colour.
3. Set up equipment as in diagram below.
Results
• Water will rise highest at the end where the pores are close together and
very little rise will occur at the other end.
Conclusion
• The larger the airspaces the less moisture will rise up by capillary action.

EY4106
PROJECT PORTFOLIO

EXPERIMENTAL WORK
Students are required to submit a record of three experiments that they undertook
during their coursework. These experiments must be their own individual work and it
is recommended that they be related to their project. The Chief Examiners Report
explains:

“Candidates who investigated aspects of the coursework, constructed a
hypothesis, investigated this hypothesis and derived a conclusion succeeded in
obtaining high marks. Such an approach is to be commended and candidates were
rewarded accordingly….. Candidates are advised to relate the experimental work to
some aspect of the coursework undertaken. This provides candidates with an
opportunity to hypothesise and to analyse in detail aspects of the coursework and to
record the results of such analysis. It also provides candidates with an opportunity to
undertake unique experimental work. Candidates who submit derivative
experimental work cannot achieve the full complement of marks. It is recommended
that three experiments be undertaken by each candidate. A detailed description of
each experiment, including a clearly stated objective, should be recorded in the folio
for assessment. Group or class experiments do not comply with the regulations of
the SEC.” Department of Design & Manufacturing Technology (Techno Teachers Association, 20

EY4106
PROJECT PORTFOLIO
EXPERIMENTAL WORK
The following is sample list of areas where students can engage in
experimentation:
1. Tests on Jointing methods for project:
a. Mortise & tenon vs. biscuit/domino vs. dowel
b. Dovetail vs. finger vs. mitre
c. Nailed vs. screwed vs. glued only

2. Test on moisture content of wood
a. Moisture content of wood ( see next page)
b. Absorbance of wood (place dry wood in damp situation and test how much
water it has gained). You can also test quality of exterior finish to see which one
allow most moisture to soak into wood.


EY4106
PROJECT PORTFOLIO

3. Test on quality of finishing:
a. Compare various finishes (varnish, oil, wax etc.) for qualities or suitability for
project. Compare under: i. Cost
ii. Ease of application
iii. Durability (scratch resistance, heat resistance, weather resistance)
iv. Aesthetics (how well it looks when finished)

4. Test on strength of structures:
a. Triangulation test on roof members (model of rafters/ roof truss) the more a
roof is triangulated the stronger and stiffer it should be)
b. Bending strengths of timbers
i. Fix on end of sample and tie weights on other rend and compare the
deflection (amount of bend) of various types of timber OR compare same
wood type (e.g. red deal) but compare thickness vs. width of samples (e.g.
10mm * 5mm piece vs. 10mm * 10mm piece vs. 15mm * 10mm piece etc.


EY4106
PROJECT PORTFOLIO

This list is by no means exhaustive. The syllabus
outlines further areas where students can engage in
experimentation. Specific project areas can also
lead to other experiments. For example a project on
domestic electricity can include experiments on
electrical circuits, resistors, photovoltaic cells etc.
