The aim of this activity is to develop the students’ inquiry competence. In this sense, helped by a specific scaffolding, students in groups plan and carrying out their own research to understand what and how different substances limit (or not) the bacterial growth.

Students’ resources

Starting with one of the presented cases in the activity 1 in which a girl has a urinary tract infection that persist even after the antibiotic treatment. Then the report obtained after an antibiotic sensitivity test have been presented and analysed by the students.

After that, students have been involve in an inquiry-base activity. Helped by a scaffolding students (in groups) must plan and carry out an experiment that simulates an antibiotic sensitivity test. Although similarities with the real test, they will use not pathogenic bacteria and common substances (not antibiotics) to carry out the experiment and to observe and analyse which substances limit the bacterial growing and which not.

Teachers’ resources

Although the scaffolding tool can help students in planning and carrying out their own research, it is essential that the teacher also has an active role in guiding this process.
