📖 What is Biology?📖 Apakah Biologi?

🔑 KEY CONCEPT:🔑 KONSEP UTAMA: Biology (from Greek: bios = life, logos = study) is the scientific study of living organisms and their interactions with the environment.Biologi (daripada Greek: bios = hidup, logos = kajian) ialah kajian saintifik tentang organisma hidup dan interaksi mereka dengan persekitaran.

🔬 Scientific Method🔬 Kaedah Penyiasatan Saintifik

7 Steps:Langkah-langkah: Identify problem → Form hypothesis → Plan experiment → Collect data → Analyze → Conclusion → ReportMengenal pasti masalah → Membuat hipotesis → Merancang eksperimen → Mengumpul data → Menganalisis data → Membuat kesimpulan → Menulis laporan
💡 Memory Trick:💡 Trik Ingatan: "I Hate People Calling Everyday At Custard""Bio = Bios (hidup) + Logos (kajian)"
Scientific Method Flowchart 1. Observe Identify a problem 2. Hypothesis Testable prediction 3. Experiment Test with variables 4. Data Record results 5. Conclude Analyze & accept/reject 6. Report Share findings If rejected -> new hypothesis SPM GUARANTEED Identify the steps

SPM 2021 Paper 2

A student wants to investigate the effect of light intensity on the rate of photosynthesis.Seorang pelajar ingin menyiasat kesan keamatan cahaya ke atas kadar fotosintesis.

(a) State the manipulated variable. [1 mark]Nyatakan pembolehubah dimanipulasikan. [1 markah]

(b) State the responding variable. [1 mark]Nyatakan pembolehubah bergerak balas. [1 markah]

(c) List two constant variables. [2 marks]Senaraikan dua pembolehubah dimalarkan. [2 markah]

📌 Exam Tip:📌 Tips Peperiksaan: Manipulated = What you CHANGE, Responding = What you MEASURE, Constant = What you KEEP THE SAMEDimanipulasikan = Apa yang DIUBAH, Bergerak balas = Apa yang DIUKUR, Dimalarkan = Apa yang DIKEKALKAN SAMA
