This exploration allows you to travel to the tiny world of DNA. Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll also see the intricate bending and winding that takes place within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell. This resource is part of the Biology Links for One Laptop Per Child course which contains units on Exploring Life; The Cell; Genetics; Mechanisms of Evolution; The Evolutionary History of Biological Diversity; Plant Form and Function; Animal Form and Function; Ecology; and Astrobiology.

I think that the visualization in the flash animation is good. It does a good job of breaking DNA down into 15 compartments that help students understand how it is such an important element of the human body.
However, I think that this is very passive for a lesson. I don't think that it actively engages students. If this is done in class, there is a high possibility that students will just click through the activity without actually reading the material.
I also think that the animation does not necessarily provide an equal learning opportunity for students with an IEP. There's no audio to accommodate students with who are blind or have dyslexia and will have difficulty reading the text.
The following lesson plan provides great insight for students to go through the various levels of cellular organization in the human body. I think it does a great job of showing how these levels of organization are related to one another and build upon one another to conceptualize the entire scientific concept. I feel that this lesson could be improved if you added more content that is focused on student participation and active learning. As is the current lesson only requires students to click on a few various links and magnify the different levels of organization of the human body. I feel that this website if combined with other sites or learning modules that focus on investigative learning would be a great part of a human system unit.
What the above reviewer said is true; it is mostly just clicking with some reading as well. It would be up to the teacher to provide more active thinking. However, to see where DNA is located and the different levels of organization of the DNA, it is a very nice (but easy to understand for students) animation.
nice animation, but just passive click through, no exploratin or active thinking/processing involved.
this is way cool!
