Biology Lesson

Last night my Dad read a biology book called "Introduction to Biology" by John Holzmann. `While my Dad was reading I took some notes, here is a picture of them.
 When you look at the picture you can see that there are arrows pointing to the different keywords like it starts at the keyword Wondering then from that phase it goes into Theory and Hypothesize and then comes from Hypothesize and Theory into Experiments and from Experiments goes into Observing, Testing, and Hypothesize and from Observing into Testing etc.
