- So?



~ ANSWERING OPEN-ENDED ~


1) Read the question once first

2) HIGHLIGHT the key words

3) Identify the TOPIC of the question

4) Which concept in the topic is this question testing me on?

5) What are the key words/pointers to this concept?

6) Answer the question in DETAIL using Science terms/key words.


Electricity


1) Electrical Conductors allow electric current to flow through easily: Silver, Copper, Aluminium, iron, gold

2) Electrical Insulators do not allow electric current to flow through easily: Rubber, Plastic, Fabric, wood, etc.

3) ELECTRIC CURRENT FLOWS ...

4) Electrical conductivity of a material .....

5) Open circuit ...Closed circuit ... gap ....series....PARALLEL   (Better know how to SPELL !)

6) Electricity can cause electric shocks, fires and burns (when appliances are overheated due to high currents flowing through them).

7) CONNECT

8) Negative end, positive end




Safety precautions:

Do not touch electrical appliances or power points when your hands are wet. Water conducts electricity.

Do not poke anything into electrical power points

Do not use apliances which are damaged or have exposed wires

etc.


Fossil Fuel

Fossil fuels include oil, coal and natural gas.

They are formed from the remains of plants and animals which lived very long ago and they cannot last forever.

Burning of fossil fuels produce harmful matter such as poisonous gases. They pollute the air and cause damage to our health.

~Do you know these? ~

Human & Plant Reproduction

1) What is gestation and how long is it?

2) What happens during fertilization?

3) What is "maternal" and "paternal"?

4) Name some inherited traits and non-inherited traits

7) Name all the Male and Female parts needed for reproduction in plants

8) Name all the Male and Female parts needed for reproduction in humans.





Water & Changes of State

1) Boiling ONLY OCCURS @ 100-degree celcius!

 Anything before 100 is heating, has not boiled yet !!

2) 0-degree celcius can be FREEZING or MELTING! Depends where your graph is heading to!

3) A pure substance will have a FIXED melting/boiling point.

4) Why is the temperature constant during melting/freezing/boiling

5) What is the difference between Boiling & Evaporation? What is the similarity?

6) What are some factors that affect the rate of evaporation?

7) How does water droplets/dew form on the window, etc. ?

~ Science Practice Paper 2 ~

31a) When the water was heated, the hot water vapour came into contact with the cooler surface of the funnel, lost heat (1M) and condensed (1M), thus forming water droplets on the underside of the cover.



b) The liquid is colourless and tasteless.
(Don't be tricked !!!

Water vapour condenses to form the water droplets!

The liquid will not be coloured, if not your water vapour in the air would already be coloured too!

Also, salt is solid, it will not evaporate! Only the water! Salt will be left behind in the beaker!)



32) 






33a) He should change only one variable / physical condition for each seed.

b) Seed R

c) Germination of seeds does not require mineral salts, so there is no need for soil to be used.






34a) The seeds are dispersed by animals which ate the fruit.

b) The small, hard seeds are swallowed by the animals, but are undigested (1M). They are dispersed when the animals passed out the seeds (1M).    *See! Got to be very detailed!* 





35a) Blood vessel P. Blood from the heart going to the lungs has the least amount of oxygen as oxygen is used by the other parts of the body.

*READ the question properly!

They asked for WHICH BLOOD VESSEL and you are given blood vessels P, Q, R & S!

Do not give me other answers like A, B, C, D, veins, capillaries, arteries...etc.*



b) It is to supply digested food and oxygen quickly to other parts of the body to release more energy

*Many of you will miss out the 2nd part! Important! Must talk about ENERGY always!*





36a) The water is used by the leaves for photosynthesis / to make food.

b) Water moves in one way in plants while blood circulates throughout the human body.




37a) T
b) F Blood carries digested food, YES. But now the question is only asking about RED BLOOD CELL. It only carries oxygen!
c) T
d) F




38a) The bulbs in both circuits are arranged in series, that is why the brightness of the bulbs are the same in both circuits.

b)



39a) Ali was investigating the flexibility of materials / if the materials are flexible or not.

b) Thickness / length of material.



40a) She should bring each electromagnet close to some paper clips / pins/ staples. (0.5M)

        She should count the number of paper clips / pins / staples attracted by each electromagnet. ( 0.5M)

        The more pins attracted, the stronger the electro magnet. (1M)


b) Use different number of batteries for each iron nail but same number of coils around each iron nail.





41a) Group A: Plants
        Group B: Fungi

b) He is wrong. Moss is a non-flowering plant not fungi. It can make its own food. *Elaborate! Explain!*





42a) Translucent / Frosted

b) As the thickness of Material Z increases, the amount of light passing through it decreases.

c) The experiment will not be accurate if other light sources are captured by the light sensor.



43a) As the flask was heated, the air in it gained heat and expanded causing it to be forced out of the glass tubing and into the coloured water as air bubbles.

b) The water would move up the glass tubing.

c) The air in the flask cools down and contracts (0.5M). The water in the beaker then moves up to take up the space previously occupied by air.



44a) This is to ensure that the reading is consistent and more reliable.

b) In Flask B, air was able to escape through the outlet (0.5M) of the flask. This enabled water to enter to occupy its space (0.5M).

c) Remove the cork from the mouth of the flask and lift the funnel above the flask.

~ Answers ~

Answers for those people who stayed back during recess to do the extra questions.

Sorry that you've got to tilt your head!
I have no time to edit and straighten the pictures.


* Error in Q5. answer. 

2nd step should be "97/4" instead of 96/4.
Ans: 23 11/12







~ MATH CA Pointers ~

Important Pointers You MUST know:

1) Multiplication & Division of Mixed numbers / fractions

2) Converting fractions to decimals / decimals to fraction

3) Volume = Length x Breadth x Height

4) Volume = Area x Height

5) Height = Volume / Area

6) Area = Volume / Height

7) 1000 cm3 = 1000 ml = 1L

8) Rounding off to 1 Decimal Place / 2 Decimal Place

9) Conversion from ml to L , L to ml, g to KG, KG, to g , etc.

10) Area of Triangle = 1/2 x Base x Height

11) Height of Triangle is always PERPENDICULAR from BASE
to HIGHEST POINT of triangle

12) Area of Square, find the sides

13) Perimeter is the OUTLINE of the figure

14) Area is the space inside the figure (cm2 / m2 / km2)

15) Conversion of fraction to SIMPLEST FORM

16) BODMAS ( Bracket, Division, Multiplication, Attraction, Subtraction)

17) HEURISTIC Booklet

18) NO ml divide by Litre or Litre divide by ml, KG divide by grams, etc.

Example:
1.5L divide by 300ml = 1.5 divide by 300 = 0.005 (WRONG!)

Must convert all to the same units before dividing or multiplying etc.!     1500ml divide by 300ml = 5





Things you MUST remember:

1) NEVER FORGET to write the UNITS. Even in the WORKINGS!!!

2) Give a reason first for number sentence before even doing.

Example:    Marbles left -----> 25/100 x 400 = 100 marbles


3) Highlight KEY WORDS




4) READ the question again and again and AGAIN.

Solve 1 SENTENCE AT A TIME.

BREAK the problem up and solve it slowly part by part. 

Use pictures or diagrams or models, etc. to allow yourself to have a clearer picture of the question.




5) Be careful! Stop using MENTAL calculations.
    Do working to get METHOD MARKS !
    Working must be clear and makes sense if not NO Method Marks.
