You are cutting it very fine I would suggest. To stand and lecture for forty minutes takes some doing and fair amount of preparation I would suggest, and you havent even choosen a subject yet. Not a clue what to suggest if honest, perhaps something you know about all ready would be a sensible option. Anyway, hats off to you and best of luck at the lectern.
You're leaving it very late for a 40 minuter!!! As posted above, choose a subject you know well, it may be the most bone one but with a bit of flair and some decent humour etc. you'll pull it off.
If you hide behind the lectern and speak in monotones, FAIL!!!!!
Be up front, relaxed posture and scan the audience trying to make quick eye contact. If you know your subject and practise a few times you'll only need bullet points on the back of a fag packet. Don't over use powerpoint, use short videos, make it pleasing to the eye but keep it simple. Flashy presentations are hard to look at if you're trying to absorb info at the same time.
Be prepared for some in depth answers at the end, if you don't know say so. 'I'll get back to you shortly with the answer' etc.
When Albert Einstein was making the rounds of the speakers' circuit, he usually found himself eagerly longing to get back to his laboratory work. One night, as they were driving to yet another rubber-chicken dinner, Einstein mentioned to his Butler (a man who somewhat resembled Einstein in looks & manner) that he was tired of speech making.
"I have an idea, boss," his Butler said. "I've heard you give this speech so many times. I'll bet I could give it for you." Einstein laughed loudly and said, "Why not? Let's do it!" When they arrive at the dinner, Einstein donned the Butler's black jacket and striped pants and sat in the back of the room. The Butler gave a beautiful rendition of Einstein's speech and even answered a few questions expertly.
Then a supremely pompous professor asked an extremely esoteric question about anti-matter formation, digressing here and there to let everyone in the audience know that he was nobody's fool. Without missing a beat, the Butler fixed the professor with a steely stare and said, "Sir, the answer to that question is so simple that I will let my Butler, who is sitting in the back, answer it for me."
