Berikan sebab mengapa planet Pluto mengambil masa yang lama untuk membuat satu putaran lengkap menggelilingi matahari.

Kerana kawasan orbitnya besar.

Berikan sebab mengapa planet tidak berlanggar antara satu sama lain ?

Kerana planet bergerak mengikut orbit masing-masing

Gambarajah di bawah menunjukkan satu litar.

Pemerhatian : Mentol menyalaa) Berikan inferens berdasarkan pemerhatian di atas.

Mentol menyala kerana paku adalah konduktor

Berikan inferens berdasarkan pemerhatian.

Pemerhatian :pokok A kekal hidup, pokok B mati

Pokok A hidup kerana mendapat udara dan cahaya matahari, pokok B mati kerana tidak mendapat udara dan cahaya matahari.

Pemerhatian yang di catatkan oleh Nellina seperti berikut:-

Kereta mainan bergerak laju atas permukaan kaca.Kereta mainan bergerak perlahan atas permukaan kertas pasir.a) Tuliskan dua inferens berdasarkan pemerhatian di atas.

i) Permukaan kaca yang licin menyebabkan kurang geseran.

ii) Permukaan kertas pasir yang kasar menyebabkan geseran lebih kuat .

THE TECHNIQUE FOR THE TECHNIQUE FOR ANSWERINGANSWERING

something that changes in different situations

Terdapat tiga jenis pemboleh ubah :- a) what to changed ( WTO)/Pemboleh ubah dimanipulasi (PM) - Sesuatu yang berubah-ubah atau tidak sama dalam

satu eksperimen

b) What to observed/measured ( WTO ) / Pemboleh ubah bergerak bals ( PG )

- Hasil sesuatu eksperimen/sesuatu yang ingin diketahui.

c) What is kept the same / Pemboleh ubah dimalarkan - Sesuatu yang sama atau tidak berubah dalam satu

eksperimen tetapi harus mempunyai parimeter.

THE TECHNIQUE FOR ANSWERING

REMEMBER!!! FOR THIS QUESTION, YOUR ANSWER SHOULD START WITH WTC

The number of swings depends on the length of strings

What is the relationship between the two variables in the statement above?

The more the length of strings, the lesserthe number of swings.The longer

Write a relationship between the two factors in the statement above.

The more the number of chicks in a container, the greater the competition among the chicks.

Which one is C and which is MO?

The brightness of the bulbs is influenced by the number of dry cells.

The more the number of dry cells,the more the brightness of the bulbs

An investigation was done to study the relationship between the number of sponges used and the amount of water absorbed. Table 1 above shows the results obtained.

What does happen to the volume of water absorbed when the number of sponge increases?

The more the number of sponge, the more the volume of water absorbed.

610141822

What is the relationship between the number of pupils having diseases with day ?

As the day increases, the number of pupils having disease X increase.

Two similar potted balsam plants are used in this experiment, They are labelled A and B. A transparent plastic bag is placed over plant B and tied at the base. Then, two potted plants are placed outdoors and watered every day for two weeks .

State the relationship between the presence of air and the condition of the plants.

If/ When the plant does not get air, the plant will die.

THE TECHNIQUE FOR THE TECHNIQUE FOR ANSWERINGANSWERING

Yazid poured 50 cm³ of water into a measuring cylinder. He had several marbles of the same size. He wanted to measure the volume of each marble. He dropped the marbles, two at a time , into the cylinder. The volume of water was recorded each time he dropped the marbles as shown in the table below.

The number of marbles

Predict the volume of water if 20 marbles were dropped into the measuring cylinder.

70 cm³

2 marbles = 2 cm³

1 marbles = 2 ÷2=1 cm³

20 marbles = 20 cm³ + 50 cm³

= 70 cm³
