    I have a speech on evolution and i was wondering if anyone knew of any models video excerpts or handout type things i could use?

    Maybe a quick activity that my audience can get involved in?

    Ha depending on the size of the audience you can give someone a sentence on a piece of paper, and have them pass it on verbally down a chain of individuals to see if changes accumulate. It's not quite analogous to evolution though.

    Tell half of the room that thy have disfigurements, and that means that they can't survive long enough to pass on their 'retarded' genetic material - the other half are normal, and therefore can live long enough. Then add something about how this factor weeds out the people with genetic disadvantages, and that's basically how evolution workd.
    You might also have to put in something about the people with genetic advantages - longer legs, better eyesight - and say that they wuill live longer and therefore be able to produce more offspring!

    Evolution is more about relative reproduction rates than absolute ones such as: preproduction vs no reproduction.

    You could analyze two families.

    See how many offspring one had after 3 generations, and compare that with another family who had less or more.

    Then speculate whether this could influence the relative propagation of genetic material within a small population.

    Hand out a large glass of milk to everyone as they enter the room and have them drink it before they can go in. Block the exits. Nobody will forget that day.

    Take a look at videos by Potholer54 on YouTube, particularly the "Made Easy" series, a fair chunk of which are dedicated to explaining evolution. You might find inspiration there. The videos are also copyright-free so you could even show them if you wanted.

    NOVA online has some teachers guide type stuff. In the Classroom Activities section there is a section on evolution.

    One activity is called "From Wolf to Dog," and has students learn through an evolution card game how selective pressures can affect an organism's evolution. It's for Grades 6-8, 9-12. I've not looked at the details myself, although I can see that there are bunch of PDF's to download; you also need scissors and dice,

    Use an alife program. You can give your speech and project the simulation behind you, and with any luck by the end of your speech you'll have seen some evolution.

    Nanopond is what I'd recommend.

    I like the comparison of biological evolution to the diversification of language. How if two populations seeded by the same language are left isolated from each other for a long enough period of time, subtle variations in slang will eventually result in distinct separate dialects. If left isolated even longer, the two languages may eventually become unrecognizable to each other. It would probably require a whole section of your presentation, but a tree diagram similar to this next to an evolutionary tree diagram might be helpful.

    No offense, but I don't think this would be a good choice. The inheritance and change of cultural traditions like language have fundamentally different mechanics than the inheritance and change of gene-based biological systems. They do sometimes result in similar outcomes, but it's not something I'd want to mix up together if I could avoid it.
    Man can will nothing unless he has first understood that he must count on no one but himself; that he is alone, abandoned on earth in the midst of his infinite responsibilities, without help, with no other aim than the one he sets himself, with no other destiny than the one he forges for himself on this earth.

    You might try looking through this book for ideas:
