Bacteria Spreader: practical apparatus
What Bacteria Spreader Is Used For
Bacteria Spreader is practical apparatus for handling cultures during microbiology practical work. In GCSE or introductory practical science, the annotated diagram helps connect the apparatus to the method, measurement, or observation being tested.
How To Use It In An Exam Answer
Use the marker labels to name the apparatus first, then say why it is suitable. A strong answer links bacteria spreader to handling cultures during microbiology practical work, rather than only saying that it is used in a lab.

Common Trap
Do not describe apparatus by appearance only. Marks usually come from explaining its function in the practical method.
