Ever wanted to do a play but not done it because you teach Science? No problem! Here is a script I have used for a theatre play fully justified in a Science context! With minimal resources, short duration (about 20 minutes) and for a class set (around 25 people, plus minus a few if you tweak the script a little). Each character says only a few sentences avoiding complex language, there are 5 dialogue sequences (acts). Ideal for year 6 or 7 students, it can help with laboratory safety awareness both for actors and for spectators, and has a some annotations on how to improvise the scenario and attrezzo in a normal classroom. Since it can be fitted (preparation and tidying up included) into one single lesson, I went round the school making the play for other class groups and it was a great success! Also great fun!
