This document provides guidance on techniques for answering science questions in an exam. It outlines the key elements to include in responses such as the aim of an experiment, variables being tested, hypotheses relating variables, and patterns observed. Students are advised to state the aim as investigating relationships between a manipulated variable and responding variable. Hypotheses should relate how the responding variable changes as the manipulated variable increases or decreases. Conclusions should follow the pattern of "if X, then Y".
Teknik menjawab sains
- 1. TEKNIK MENJAWAB SAINS (BAHAGIAN B)
- 2. INFERENS 1. Inferens berbanding : - Jika terdapat dua perbandingan: Eg: Pokok A mendapat ruang yang mencukupi berbanding pokok B. - Jika terdapat lebih daripada dua perbandingan: eg: Pokok A paling subur kerana mendapat ruang yang mencukupi.
- 3. TUJUAN / TAJUK EKSPERIMEN/ PENYIASATAN • Untuk menkaji/ menyiasat hubungan / kaitan di antara ……………(PMN)….. dengan / dan ……….(PBG) …….. • Eg: Untuk mengkaji hubungan di antara bilangan titisan air dengan saiz kulat pada roti
- 4. PEMBOLEHUBAH 1. Dimalarkan (yang sama / yang tetap / yang tidak berubah) 2. Dimanipulasikan (yang mesti diubah / yang berbeza / tidak sama) 3. Bergerakbalas (apa yang diperhati / apa yang dikaji/ hasila kajian)
- 5. HIPOTESIS / KESIMPULAN / RUMUSAN 1. Semakin …(corak)…(PMN)…. , semakin … (corak)…(PGB)…. 2. Jika ………….maka ………….. Contoh: 1. Semakin bertambah masa semakin berkurang suhu air. 2. Jika pokok mendapat air yang cukup maka pokok akan tumbuh dengan subur.
- 6. CORAK PERUBAHAN • Menaik / bertambah / meningkat • Menurun / berkurang • Sama / tidak berubah / kekal / tetap
- 7. VARIABLES 1. What to kept the same (Constant / controlled variables) 2. What to be change (Manipulated variables) 3. What to observe (Responding variables)
- 9. AIM / PURPOSE • What is the aim / purpose of the experiment / investigation? - To investigate the relationships (between )…..(manipulated variable) …. and/ towards/ upon/ on/ with .. .. (responding variable) … or
- 10. Aim/ purpose • To investigate the effect / influence of …….(mv)….. towards …..(rv) Or - To find out the relationships between ……..(mv)….. and ….(rv)…..
- 11. INFERENCES • Give reason • State why Eg: Humans need shelters to protect themselves from danger, sun and rain.
- 12. Hypotesis: • Examples of question given: 1. What is the hypotesis of the investigation/ experiment? 2. What is the relation between the variables? 3. What is the conclusion can be made?
- 13. Hypotesis 1. When mv increases/decreases, the rv increases/ decreases. 2. The more/ less mv is, the longer/ higher/ shorter/ more/ less rv . 3. If / when ……………….., so ………..
- 14. Hypothesis: • Examples: 1. When the number of nichrome coil increases , the water temperature increases // vice versa. 2. The more the number of coil is, the higher is the water temperature // vice versa
- 15. Hypothesis: • Examples: 1. The more the quantity of the salt is, the longer the food can be preserved.
- 16. CONCLUSION / HYPOTESIS • Eg: 1. The plant wilted if there is no water. 2. If no food, animals will die 3. If the time increases, the temprature of water increases too. 4. The more the size of the magnet is, the more the number of pins attract.
- 17. PATTERN/ TREND • Increases • Decreases • Same / unchange
