A Murder Scene to Teach the Passive Voice

Criminal`s blurred photo:
Detect the Criminal!
PRACTICE

PROCEDURE
Prepare the murder `materials` and scene (e.g. red-tainted knife, scarf, credit cards, alluding words on the board, overturned chairs, victim, letter,…etc.)
Prepare a shadowed photo of the supposed `killer`. (preferably one of the students)
Prepare some handouts.
Let your class out until you finish preparing the `murder scene`.
Goad your students to use as many adjectives as possible to describe the supposed killer.
Guide your students in producing passive sentences about the murder scene (the form and use of passive should be already taught)
E.g. The knife is tainted by the victim`s blood.
Finally, let your students induce the rule of the passive voice.

The benefits of the `Murder Scene`
Create a motivating learning atmosphere for your students.
Practice the use of adjectives through describing the supposed `criminal`.
Drill students on the use of the passive voice through writing sentences about an `unknown` doer (In this context, the subject is an unknown criminal).
After writing sentences in the passive voice, the general rule (structure) of the passive sentence can be induced.

The murder scene may be `shocking` or `unpleasant` for some students.
The preparation of the scene may take some time. Sometimes, when the tutor is rushing to cope with the given course calendar, the `murder scene` may look inconvenient.
It is inappropriate to present the `murder scene` to students without teaching the passive voice in prior.
