biology speech

[mcoy]

I am doing a speech in chemistry about some natural resource extraction. Well it is basic stuff, but i don't have an idea where to start. I am thinking of doing something about fossil fuels. I got another speech for physics, and i need some other resource for GPS other than the ones i found at howstuffworks. Any other suggestions are definitely welcome

 

 

 

thank you in advance
