- So, Rosie and Martin, let's look at what you've got for your presentation on woolly mammoths.
- OK.
- We've got a short outline here.
- Thanks.
- So, it's about a research project in North America.
- Yes.
- But we thought we needed something general about woolly mammoths
- in our introduction to establish that they were related to our modern elephant
- and they lived thousands of years ago in the last ice age.
- Maybe we could show a video clip of a cartoon about mammoths,
- but that'd be a bit childish.
- Or we could have a diagram.
- It could be a timeline to show when they lived with illustrations.
- Or we could just show a drawing of them walking in the ice.
- No, let's go with your last suggestion.
- Good.
- Then you're describing the discovery of the mammoth tooth on St Paul's Island in Alaska and why it was significant.
- Yes, the tooth was found by a man called Russell Graham.
- He picked it up from under a rock in a cave.
- He knew it was special.
- For a start, it was in really good condition,
- as if it had been just extracted from the animal's jawbone.
- Anyway, they found it was 6,500 years old.
- So why was that significant?
- Well, the mammoth bones previously found on the North American
- mainland were much less recent than that, so this was really amazing.
- Then we're making an animated diagram.
- to show the geography of the area in prehistoric times.
- So, originally, St Paul's Island wasn't an island.
- It was connected to the mainland, and mammoths and other animals,
- like bears, were able to roam around the whole area.
- Then the climate warmed up and the sea level began to rise,
- and the island got cut off from the mainland.
- So those mammoths on the island couldn't escape,
- They had to stay on the island.
- And in fact, the species survived there for thousands of years
- after they'd become extinct on the mainland.
- So why do you think they died out on the mainland?
- No one's sure.
- Anyway, next we'll explain how Graham and his team identified the date
- when the mammoths became extinct on the island.
- They concluded that the extinction happened 5,600 years ago.
- which is a very precise time for a prehistoric extinction.
- It's based on samples they took from mud at the bottom of a lake on the island.
- They analyzed it to find out what had fallen in over time.
- Bits of plants, volcanic ash, and even DNA from the mammoths themselves.
- It's standard procedure, but it took nearly two years to do.
- So why don't you quickly go through the main
- sections of your presentation and discuss what actions needed for each part?
- Okay.
- So for the introduction, we're using a visual.
- So once we've prepared that, we're done.
- I'm not sure.
- I think we need to write down all the ideas we want to include here.
- Not just reliable memory.
- How we begin the presentation is so important.
- You're right.
- The discovery of the mammoth tooth is probably the most dramatic part,
- but we don't have that much information,
- only what we got from the online article.
- I thought maybe we could get in touch with the researcher
- who led the team and ask him to tell us a bit more.
- Great idea.
- What about the section with the initial questions asked by the researchers?
- We've got a lot on that, but we need to make it interesting.
- We could ask the audience to suggest some questions
- about it and then see how many of them we can answer.
- I don't think it would take too long.
- Yes, that would add a bit of variety.
- Then the section on further research carried out on the island,
- analysing the mud in the lake.
- I wonder if we've actually got too much information here.
- Should we cut some?
- I don't think so, but it's all a bit muddled at present.
- Yes, maybe it would be better if it followed a chronological pattern.
- I think so.
- The findings and possible explanations section is just about ready,
- but we need to practice it so we're sure it won't overrun.
- I think it should be OK, but yes, let's make sure.
- In the last section, relevance to the present day, you've got some good ideas,
- but this is where you need to move away from the ideas of others and give your own viewpoint.
- Okay, we'll think about that.
- Now, shall we show you some of the...
