Unit 3 Investigative and practical skills in AS Biology
Practical work carried out in the context of Units 1 and 2 should enable candidates to gain experience of collection of reliable quantitative data where
  • colour change takes place
In addition to these specific examples the colorimeter has many other applications that can be used to fulfill the objectives described in detail in the AQA specification document to teach and assess practical and investigative skills such as
