It helps to know what you are presenting about.
Guidelines:
Start with a 'welcome to [subject matter] presentation by ....' page
Go on to an introduction (include a quoted dictionary definition of the subject and basic history, but make sure you explain the definition), then say in this presentation what is going to be talked about and who will go over what. say who will go onto the first topic and what the topic is
Main body:
1 topic per person
1 person to introduce and conclude the presentation.
each topic should be explained for what it is, what it's used for and what advantages there are if it's social science related (geography, economics, sociology, history, PSE, etc.)
if it's art related (english, art, music, etc.), say what is the idea, why the author included in it, what are the problems, what is good about it?
if it's science related (biology, chemistry, physics), say what it is, why it happens, and under what conditions that will happen and what evidence is there (basically bombard people with facts)
Summary/Conclusion:
What was discussed (briefly in bullet points - prefably the title of each slide per point)
say what new research is out there/what the author's next book/what is the artist is doing now and the possible future it might lead to
have a page saying thank you for listening and asks whether there are any questions. If you can't answer the question they ask, say that you're sorry you can't answer it but give them recommendations where to find out more (books, websites, encyclopedias, etc.).
Also have a page showing your bibliography (just to show that you have done some work).
A typical bibliography should have:
wikipedia, encarta, newspapers/textbooks/novels, other websites, other books
Presentation techniques:
have your script low so you can glance at it when you read. Make sure when you present, you look from the back left corner of the audience to the right back corner, before you read/say your next point
speak clear, slow and loud (but do not shout - it's voice projection, not aggression)
look happy/pleased, your audience will lighten up
a few jokes (if they are good and is related to the topic)
be energetic when presenting (like you're going to have problems with that) - when you're enthusiastic and interested in what you study so will the audience in about 2 minutes into the presentation
Rehearse the presentation at least 3 times before doing it - either during lunchtimes, after school or at home. You will find things you want to change or see things that you think you can do better. Find someone to go over the presentation with you so you know it's clear to them and to the people you want to present to.
Extra posh tips:
have a quote from a poem/ book of quote that explains the moral of the presentation. e.g. if your presentation is about how things never go to plan, you can quote things from the Of Mice and Men poem (you should be studying this for English, if not ask an English Lit teacher). If your presentation is about how art is essential to society, there's a quote by Albert Einstein you can use.
If you use quote, explain the quote and say what it means. say how it is related to the topic then go into the topic.
Possible topics:
What is art?
Are video games bad?
Why do boys like football/fast cars so much?
What is the life of a teacher like? (if you do this, make sure their names do not appear on the presentation, just say Teacher A, B and C, etc. or alpha, beta, gamma (using greek letters) if you want to be posh)
Is education necessary?
Should dating be permitted for under 18s?
Does having a legal drinking age limit lower the number of drinking related incidents?
Hope this helps
