39. Activity 5: Role play 1
Student B: “Hey (name) don’t forget your safety glasses”
Student A: “I’m not wearing them – I’ll look stupid”
Student B: “Don’t be daft – everyone wears them. Anyway, if something flies into your eyes you could be really badly hurt.”
Student A: “Don’t mind that – I’ll be grand”
Student B: “I’m serious (name) you really should put them on – anyway, you heard (teacher) if anyone is caught not wearing the safety glasses (s)he’ll turn it off for the rest of the class”
Student A: “Would you just get lost and mind your own business”
Student B: “Okay – suit yourself. But I’m telling (teacher) ‘cause if you get hurt none of us will be allowed to use the lathe ever again”
Student A: “Alright, alright – I’m putting them on”
Student B: “Good – call me when you’re finished, I want to use it after you”.

40. Activity 5: Role play 2
Student A: Throws a waste piece of wood/ plastic/ steel at a group of students
(Remember this is a role play – don’t actually throw anything!!)
Student B: “Cut it out (name)”
Student A: “Ah, don’t be such a loser, I’m only messing” Throws another piece.
Student B: “Listen, if you hit someone in the eye it could be serious”
Student A: “Who left you in charge? I’ll do whatever I like” Throws another piece.
Student C: “Would you ever cop on”
Student B: “Stop now or I’m calling (teacher)”
Student A: “Alright, alright – I’ll stop”. Student A & B look at each other and throw their eyes up.

41. Activity 5: Role play 3
Student B: “(Name) you should lower the guard before you use that”
Student A: “What do you mean?”
Student B: “Well, the guard should be just above the work-piece. The less of the blade exposed, the less likely you are to get injured.”
Student A: “Oh right… Could you remind me how to lower it? I can’t remember.”
Student B: “No problem – you just twist this…” Shows the student how to lower the guard.
Now, go ahead and make up your own role play…
