• Suggest improvements or alternative approaches
• Assess the reliability and validity of data
• Discuss ethical considerations if relevant

Providing balanced and reasoned evaluations demonstrates higher-level understanding.

Sample Questions and Model Answers for Pearson Biology Scientific Skills

Sample Question 1: Describe how to investigate the effect of light intensity on photosynthesis.

To investigate the effect of light intensity on photosynthesis, an experiment can be designed using aquatic plants like pondweed. The setup involves varying light intensities using different distances from a light source while keeping other factors constant such as temperature, carbon dioxide concentration, and the type of plant.

Procedure:

1. Place pondweed in a test tube filled with water and bicarbonate solution.
2. Expose the setup to light sources at different distances representing varying light intensities.
3. Allow the plants to photosynthesize for a fixed period, such as 10 minutes.
4. Measure the oxygen produced by counting bubbles or using a dissolved oxygen sensor.

Results can be recorded and plotted to analyze the relationship between light intensity and the rate of photosynthesis. Ensuring consistent conditions and multiple repeats improves reliability.

Sample Question 2: Analyze the data showing the effect of temperature on enzyme activity.

| Temperature (°C) | Rate of Reaction (units/min) |
|------------------|------------------------------|
| 10               | 15                           |
| 20               | 35                           |
| 30               | 50                           |
| 40               | 45                           |
| 50               | 20                           |

Interpretation:

• The enzyme activity increases with temperature up to 30°C, indicating optimal activity at this point.
• Beyond 30°C, the rate declines, likely due to enzyme denaturation at higher temperatures.
• This data suggests that enzymes have an optimal temperature range for activity, and deviations can impair function.

Sample Question 3: Evaluate the reliability of a survey measuring students’ dietary habits.

When evaluating the survey's reliability, consider factors such as sample size, sampling method, and question design. If the survey sampled only students from one class, its findings might not be representative of the entire school population, reducing reliability. Similarly, ambiguous or leading questions can bias responses, affecting accuracy. To improve reliability, the survey should use random sampling, clear questions, and include a sufficient number of participants to account for variability. Cross-checking responses with other data sources or repeating the survey can also enhance confidence in the results.
