I saw an interesting article on science of eggs here.
In plain English terms, they discuss what happens when you heat egg white, beat egg whites, and use egg yolks as an emulsifier to mix oil and water.
The article manages to show the readers what is happening chemically without getting too technical. If you need to write scientific subjects for non-science readers, you should read this article. It will show you a great way to discuss science without causing your listener's eyes to glaze over and without insulting the audience by making it sound like you are talking to kindergarten kids.
