The Situation

Getting high school students to read a textbook can be like pulling teeth. With this explanimation, I helped an anatomy and physiology teacher take a different approach. One concept students were struggling to understand was how oxygen in the air we breath reaches the cells of the body to be used as energy. I talked to the teacher to grasp students' most common points of confusion.

The Solution

I went back to my high school notes (yup, I'm a packrat) to help me get in the mindset of a high schooler trying to understand this concept. I compared these notes to two different textbooks to get an idea of how the info is typically presented and how I could fill in any gaps in understanding. I broke down the physiological steps and explanimated them to help students visualize the process at each key point in the body.
