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
-
demonstrate and describe ethical, safe and
skilful practical techniques, selecting appropriate
qualitative and quantitative methods
-
make, record and communicate reliable and valid
observations and measurements with appropriate
precision and accuracy
-
analyse, interpret, explain and evaluate the
methodology, results and impact of their own and
others' experimental and investigatory activities in
a variety of ways.
