I believe that Birke Baehr was trying to tell his audience to eat organic to save our world from bad chemicals that they use for our food, also so we eat healthier.
Birke always had a clear and strong voice so the audience could hear him. And Birke used hand gestures but used them to much. Like the other TED talks he let the audience laugh and Birke wouldn’t speak over them, and he said thank you to stop them laughing.
Birke used a microphone a speaker and a projector to help show what he was presting.
He always had eye contact with his audience and instead of just staying in the one spot he moved around a bit.
I believe that Richards message was that there are other ways to stop animals from eating there live stock instead of killing them.
Richard practised his lines and he never used a script to help him out. He talked clearly into the mic the whole way through the talk. Richard let the audience laugh and he wouldn’t talk over them like Thomas from the last TED talk.
To help make the message clear Richard used a microphone and a projector.
Richard used the right photos on the projector and he timed the photos with what he was saying.
I understand that one of Thomas’s main messages was to encourage kids to make and design their own apps so other people can play them. Thomas convinces the audience that kids are smarter than teachers with technology.
Thomas always had eye contact with the audience and used lots of hand gestures. Sometimes he would make a joke but not go away from the subject. He let the audience laugh and he didn’t talk over them.
To help get the message to the audience, Thomas used a microphone, iPad and a projector.
Thomas used the screen behind him well by not putting anything too distracting for the audience. The iPad in his hand was only notes to tell him what to talk about.
