TIPS FOR FINDING KLU INFERENCE
Tips for finding inferences
1) There is on the keyword of the question
example:
Figure shows an experiment to show the effect of cylinder type on bone strength
that's the key word for inference - bone strength
the diagram shows an experiment studying the effect of a solution on the oxidation process
that's the key word for inference - the oxidation process
the reason for the observation..because what..so the inference is to follow the given keyword
inference (usually behind the experiment) - invisible objects
observation (is what is visible)
Example: apple slices turn brown (visible - observation)
the reason is that there is an oxidation process (invisible object - inference)

TIPS MENCARI KLU INFERENS
Tips mencari inferens
1) Ada pada kata kunci soalan
contoh :
Rajah menunjukkan eksperimen bagi menunjukkan kesan jenis silinder terhadap kekuatan tulang
itu kata kunci untuk inferens - kekuatan tulang
rajah menunjukkan eksperimen mengkaji kesan larutan terhadap proses pengoksidaan
itu kata kunci untuk inferens - proses pengoksidaan
alasan kepada pemerhatian..sebab apa..jadi inferens adalah ikut kata kunci yang diberi
inferens (biasanya di sebalik eksperimen) - benda tak nampak
pemerhatian (adalah apa yang nampak)
Contoh : hirisan epal menjadi perang (nampak - pemerhatian)
alasannya telah berlaku proses pengoksidaan (benda tak nampak - inferens)

INFERENCE WRITING TIPS for QUESTIONS WITHOUT OBSERVATION
For example, if the question asks for inference but does not ask for observation
1) must have to start with what observations it has
example:
1) Apple slices turn brown when placed in distilled water because distilled water does not have antioxidants
2) The 10 complete oscillation time of 70g plasticine is longer than 3g plasticine because 70g plasticine has large inertia
3) The number of textbooks that can be supported by a hollow cylinder is more than a compact cylinder because a hollow cylinder is stronger than a compact cylinder
4) The time for the 'X' mark to disappear from view for the temperature of sodium thiosulfate solution 70 oC is faster because it has high kinetic energy

TIPS MENULIS INFERENS bagi SOALAN TANPA PEMERHATIAN
Contoh kalau soalan tanya inferens tapi tak ditanya pemerhatian
1) mesti kena mulakan dengan apa pemerhatian dia
contoh:
1) Hirisan epal menjadi keperangan apabila diletakkan di dalam air suling kerana air suling tidak mempunyai bahan antioksida
2) Masa ayunan 10 lengkap bagi plastisim 70g lebih lama berbanding plastisin 3g kerana plastisin 70g mempunyai inersia yang besar
3) Bilangan buku teks yang dapat disokong oleh silinder berongga lebih banyak berbanding silinder padat kerana silinder berongga lebih kuat daripada silinder padat
4) Masa untuk tanda 'X' hilang daripada pandangan bagi suhu larutan natrium tiosulfat 70 oC lebih cepat kerana mempunyai tenaga kinetik yang tinggi

HYPOTHESIS WRITING TIPS
Hypothesis writing tips
In questions are usually already given or on the table
If in the table - left side (Variables manipulated) - VM
Right side (Enabler to react) - VM
So just put it in the formula
The more or less the VM, the more or less the VR
Example:
Figure shows an experiment to study the effect of the size of the reactant on the rate of the reaction
so VR - The size of the reaction material
RR - Response rate
So, the hypothesis
The smaller the size of the reaction material, the higher the reaction rate
Statement type hypothesis
Bone Strength Questions
Write a hypothesis like this. A hollow cylinder is stronger than a solid cylinder
Alloy question
Write a hypothesis like this - Bronze blocks are harder than copper blocks

TIPS MENULIS HIPOTESIS
Tips menulis hipotesis
Dalam soalan biasanya dah diberikan atau pada jadual
Kalau dalam jadual - sebelah kiri (Pemboleh ubah dimanipulasi) - PM
Sebelah kanan (Pemboleh bergrak balas) - PM
Jadi masukkan sahaja dalam rumus
Semakin bertambah atau berkurang PM, semakin bertambah atau berkurang PB
Contoh:
Rajah menunjukkan eksperimen untuk mengkaji kesan saiz bahan tindak balas terhadap kadar tindak balas
jadi PM - Saiz bahan tindak balas
PB - Kadar tindak balas
Jadi, hipotesis
Semakin berkurang saiz bahan tindak balas, semakin tinggi kadar tindak balas
Hipotesis jenis penyataan
Soalan Kekuatan Tulang
Tulis hipotesis macam ni Silinder berongga lebih kuat berbanding silinder padat
Soalan aloi
Tulis hipotesis macam ni - Bongkah gangsa lebih keras daripada bongkah kuprum
