How I Use It
I let my 3rd grade son explore the app after a recent lesson in our circulatory system. It was a nice reinforcement of those topics.
Very simple but elegant app takes students into the human body to see it at work. Nothing gross or overly realistic but a gentle introduction to body systems. It's not going to teach them deep knowledge, but it is another tool to encourage exploration of the human body. I also like that it allows for customization (girl/boy, etc) and has some interactive elements such as the heart beats faster when the character is running.
