Subject: How do different types of books affect your heart rate?

I am doing a science fair project on how different types of books affect your 
heart rate. I am planing to have people read a paragraph or two of different 
types of books, and check there heart rate before, durring, and after. My 
teacher recomended that I ask you guys for information or helpful ideas on what 
else I should do. Thanks
