Linear Electron Transport in Photosynthesis

This is a model illustrating the linear electron transport in photosynthesis. Small balls representing electrons move through the model using air pressure. While the concept of the electron transport chain can be difficult for young children to understand, watching the electrons (balls) move with their own hands will surely capture their interest.

You can see the model in action at the link below. I have revised only the text in the model from the image and the movie. Since the moving mechanism has not been altered, it should work without any issues.

I recommend printing the electron balls with the tightest pitch possible for smoother movement.
