Measure the population size of a common species in a habitat. Use sampling techniques to investigate the effect of a factor on the distribution of this species. This lesson was conducted outdoors hence why a powerpoint was not created.

This investigation has two parts:

  1. Investigating the population size of a plant species using random sampling
  2. Investigating the effect of a factor on plant distribution using a transect line.

AQA spec link: 4.7.2.1
Relevant chapter: B16 Adaptations, interdependence and competition. AQA Biology third edition textbook-Page 262-263

In doing this practical students should cover these parts of the apparatus and techniques requirements.
AT 1 – use appropriate apparatus to record length and area.
AT 3 – use transect lines and quadrats to measure distribution of a species.
AT 4 – safe and ethical use of organisms and response to a factor in the environment.
AT 6 – application of appropriate sampling techniques to investigate the distribution and abundance of
organisms in an ecosystem via direct use in the field.
AT 8 – use of appropriate techniques in more complex contexts including continuous sampling in an
investigation.
