Look across the scale to find another point where two lines align perfectly.
| | Definition | Example | |---|---|---| | Independent | Factor that is changed by the experimenter | Temperature, concentration | | Dependent | Factor that is measured as a result | Rate of reaction, mass change | | Controlled | Factors kept constant to ensure a fair test | pH, volume, time |
: Focus on 3–4 representative cells. Use clear, continuous lines and do not use shading or "fuzzy" sketching. biology 9700 practical notes
Here are some practical notes on Biology 9700, which is a Cambridge International A-Level Biology course:
Paper 5 is a written exam lasting 1 hour and 15 minutes. It tests your ability to design a theoretical experiment, evaluate data sets, and draw statistically sound conclusions. 1. How to Write an Experimental Plan (Question 1)
The Cambridge International A-Level Biology qualification, with the code 9700, is a highly respected and rigorous program that prepares students for a career in biology or further study in the field. As part of this qualification, students are required to complete practical assessments that demonstrate their ability to apply theoretical knowledge to real-world biological investigations. In this article, we will provide a comprehensive guide to Biology 9700 practical notes, helping students to understand the requirements, prepare for the assessments, and succeed in their studies. Do you need assistance with like the Chi-squared
is on the y-axis. Use at least half of the provided grid and plot points with small, sharp crosses. Significant Figures
Must include the quantity and the unit separated by a slash (e.g., Temperature / °C Consistency:
What you change (e.g., concentration). Dependent Variable: What you measure (e.g., volume of gas). Use clear, continuous lines and do not use
Paper 5 requires you to determine if experimental results are scientifically meaningful or just the result of random chance.
Measure gas volume using a gas syringe, or use colorimetry/indicator charts to track color disappearance (e.g., starch-iodine blue-black color fading). 3. Microscopy and Cytology
Used to determine if there is a significant difference between the means of two distinct groups.
Clearly identify your Independent Variable (what you change), Dependent Variable (what you measure), and Controlled Variables (what you keep the same to ensure validity). 2. Microscopy and Biological Drawings The second question almost always involves a microscope.
What you keep the same (e.g., temperature, pH). Experimental Errors: Systematic: Faulty equipment (e.g., a thermometer that is 2∘2 raised to the composed with power
