Nature Math

Hacking in the wild. As part of the Materials of Electronics class, the team explored the basics of electronics through connecting with nature. This project was done in 2 days of exploration. “Nature Math” intent is to observe the effect of sunlight and nature of conductivity among the growth of the same family plants with the help of electronic components. ‘Plant A’ and ‘Plant B’ were selected as part of the group’s two experiments.

The experiments:

Measurement of the effect of sunlight
The sunlight detector is switched on when it detects the sunlight. The circuit is composed of 3 Green LEDs, a photoresistor and resistors. The more sunlight it gets, the brighter the green LEDs become. The experiment was conducted by placing the circuit in different parts of the plant (“Above leaf”, “Beneath leaf” and “Root”) to record the LEDs brightness every two hours. This allowed the team to see how much voltage was given to the LEDs based on the position the circuit had along the plant.

Measurement of conductivity
A multimeter was used to measure the conductivity present in different parts of the plant (“Leaf beginning-Leaf end”, “Stem beginning-Stem End” and “Plant Base-First Stem”. Although the methodology was done in the correct manner, the data was not reliable due to the data being altered by rain. At least from observation, the team observed that the growth of plants is affected by the amount of water inside them (conductivity).
