Construct: Conceptualize 1. Make and state the observation
- Observation skill & critical thinking 2. Make comparison - State the similarities and differences
3. State the relationship - from the similarities and differences or state the principle/law involved.

Q.12-2008
• A new harbour is to be built at a new location. The suggested new location is either at a bay or a cape. Four models for the structure of the retaining wall are given. Table 12 below shows the location and the characteristics of the four retaining walls.
• Explain the best location and the suitability of each characterictics in Table12.
• Determine the most suitable retaining wall to be used.
• Give the reason for your choice.
Answer Characteristic Explaination / reason
The ______ Water is calmer
______retaining wall.
Decrease the wavelength / higher water pressure at
higher depth.
______ surfaceReduce energy, wave is
reflected at different direction.
______ retaining wall
Protect form high wave / overflow of water.

No 11 – characteristics ExplainationMethod of moving lawnmover- Push the handle
- Bigger force produced
Mass of lawnmower - Big
- To increase the stability
Size of cutter blade- Big size of cutter blade
- Increase the cutting area of cutting grass
The angle between handle and the horizontal- large
- Force exerted to the ground bigger
- Therefore, I choose lawnmover M, - because it has push handle, big mass of lawnmower, big size of cutter blade
and has large angle between handle and horizontal line

No 12characteristic Reason
Connection of cell- series
Increase the voltage
Connection of battery-Positive terminal of cell to negative terminal of next cell
To allow the flow of current
Connection of resistor and bulb-series
Increase the resistance
Connection of bulb- parallel
If one bulb blow, another bulb still function
