Shows a small selection of individual cells (typically 3 to 4 adjacent cells). Draw cell walls clearly as double lines. Eyepiece Graticule and Stage Micrometer Calibration
Interpreting data and identifying errors. 2. Quantitative & Qualitative Techniques 2.1 Biological Testing (Qualitative Analysis) These tests require precision in observation.
Mastering the Biology 9700 practical exam is not about memorising every possible experiment. It's about developing a confident, systematic approach to scientific investigation. By focusing on the core skills—making clear drawings, handling equipment accurately, designing controlled experiments, and analysing data critically—you will be prepared for whatever the exam presents. biology 9700 practical notes
Things you must keep constant (e.g., temperature using a water bath, volume of reagents). Use the word "volume" or "concentration" specifically—never just say "amount." 4. Precision and Data Presentation
Acidify with hydrochloric acid, boil to hydrolyze glycosidic bonds, neutralize with sodium hydrogencarbonate, then perform the standard Benedict's test. Shows a small selection of individual cells (typically
Enclose all cells with clear border lines. Place the independent variable in the first column.
Distinguish between (calibration) and random errors (human judgment). 4. Key Tips for 9700 Practical Exam Day It's about developing a confident, systematic approach to
For the A2 Level, you must demonstrate the ability to design an investigation from scratch. Define the Problem : State a clear, quantifiable, and testable hypothesis. Control Variables : Identify which variables must stay constant and specify
