Suggestions for a 20 to 30 minute presentation for school?

I would make a paper mache model of the human body and do an inside so they can see the organs. Then I'd make a little video or something, an animation depicting the growth. Then, I'd have one of you act out the different stages--for a child, act whiny and needy and for an adult, act busy and frantic. Then I'd show a quick poster on characteristics that occue during each-maybe a quick show of jeapordy..Lastly, I'd try to sound very excited about the whole boring subject, haha..

I like Crazy Lovely's idea of acting stuff out--maybe you could do disorders and what happens when genes mutate? u can test the class before ur presentation on facts about reproduction and then after your presentation quiz them again to see the difference. or maybe bring food--everyone loves free food! to show like the healthy foods that help u develop and the ones with all the chemicals and preservatives. u could take pipe cleaners and show them a model of dna replication or x and y chromosomes and have them make their own model.there's a lot u could do, good luck!
