SPM 2011 Students

All the best
You have done a great jobs last year, now is the time to harvest
God will protect and bless you
May the force is be with you

Due to extreme high request for a Facebook account
Finally i decided to start an account this year

Chemistry and Biologic

Chemistry

Paper 2

Section A

1) Definition for proton and neutrons number, isotopes

2) Neutralisation

3) Elctrolysis for molten lead bromide and sodium sulphate solution

4) Redox reaction

Section B and C

1) Periodical table for elements

2) Silicon compound, soap and detergent

Paper 3

1) Rusting iron

2) Voltaic cell (experiment)

Biology

Paper 2

1) Respiration for unicellular and multicellular organism

2) Bread mould

3) Hormonal changes in menstrual cycle

4) Musculoskeletal system

Paper 3

1) Seeding in the soil

2) Experiment on study of population of rats

Remember, I’m not sure how true are the tips, please don’t take it so serious, take it as a reference only

Good luck and all the best

Chemistry and Biology

Feel great, my tips really help

Thank God

Give me some time, i will try to find out for the Chemistry and Biology

But, remember, i'm not a Chemistry and Biology teacher, so i'm not really sure the truth of the "tips" , not like Physics, i know how true it is

Just stay tune, and please put some comments for my physics tips if you think it really help

Thanks and good luck

Final Updates And Confirmation

Structure

1) Forces in equilibrium and resultant force, scale drawing

2) Archimedes' principle, hot air ballon, high temperature make it fly higher, bigger size allow it to carry more load. Best time for hot air ballon is at night

3)Heat transfer and thermal equilibrium

4) Convex lens, ray diagram. Convex lens is best on light refraction, calculation for Snell's Law

5) Sound wave interference for loud speaker

6) Ohm's law, distance electric transmission, high resistance for long cable, using transformer to increase the potential difference

7) Logic gates circuit, using transistor to control it as a switch, with LDR, 1 is circuit ON and 0 is circuit OFF

8) Radioactivity, chemical equation

Essay

9) Pascal's principle, hydraulic system

10) AC and DC motor, dynamo

11) Convex lens on projector

12) Radioactivity, GM tube for Beta detection

Paper 3

1) Measurement by using micrometer screw gauge

2) Loaded spring, period and frequency of oscillation

Report

3) Pressure law or Boyle's Law

4)Water wave refraction, ripple tank

REMEMBER, nothing is 100%, through my teaching experience, some of my prediction that i put for Paper 2, it is appeared in Paper 3 and vice versa, please take note

All the best

Paper 3 Standard Format

Manipulated variable (MV) : Object distance

Responding variable (RV) : Image distance

Constant variable (CV) : Type of lens

Inference: RV is depending on MV

Hypothesis : If MV increases / decreases then RV increases / decreases

Aim : To investigate the relationship between MV and RV

Variable : MV

RV

CV

List of apparatus ; copy from the question

Arrangement : simple diagram

Procedure : 4 or 5 steps

1. Arrange the apparatus as shown in the diagram
2. Explain how we going to start the experiment for 1 suggested value of manipulated variable, a
3. Explain how to obtain the responding variable
4. Calculation for the responding variable (if require)
5. Repeat the experiment with__b_, _c__, _d__, and __e__

Tabulate

Manipulated Variable	Responding Variable
a
b
c
d
e

Hypothesis is accepted

Precaution for Paper 3 as i promised

Measuring Instrument
a. Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale read. ( for ammeter/voltmeter/measuring cylinder etc)
b. Take into account zero error of instrument. (for calipper/micrometer/weight scale etc.)

Spring/Hookes Law
a. make sure the spring is not loaded beyond the elastic limit.(spring return to original length when load is taken off).
b. Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale of the ruler.

Heat
a. Liquid must be stirred constantly so that temperature rises evenly.
b. Alluminium block must be wrapped with insulating material to prevent heat lost.
c. Thermometer bulb should be smeared with oil to give better thermal contact with the block.
d. Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale of the thermometer.

Light
a. Experiment must be carried out in dark room.
b. Lens, screen and object must be in line
c. Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale of the ruler.

Electricity
a. All connections of wire & other device must be tight.
b. Off the switch after readings are taken to prevent wires from heating up (resistance increase)
c. Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale of the ammeter/ voltmeter
