Some facts about air that can be useful for my project on how to build an air pump for my hydroponic system.

This is my version of the hand watered hydroponic system, pleas do let me know if this would or would not work in real life.


This is an idea i would use in a collective responsibility project for middle school classes, to teach about the value of collaboration. This version needs to be watered four times a day manually and I am thinking there could be a light that lets the students know when to "dipp" the plant in water. If they do this correctly and often enough, the plant will grow faster and more healthy.
