Great use of a recycled PET bottle!

The Recognition 
EcoClub Pizza! Harvest time is approaching for the Hanging Gardens of the EcoClub. We’ve talked the School Canteen into turning the garden’s produce into Pizza (and Salad!) for lunch on June 11.:o Stay tuned!

That said, I’ve been asked to provide updates on our Hanging Garden Project. We’ve got new ORGANIC VEGGIES, all from ‘freshly donated seeds’… Our middle/high school students have been deeply involved in building a system with planters made from recycled PET bottles, as seen on the right. What originally was a school research project, has become a multidisciplinary task (see left), and a passion for all the gardening lovers! Besides that, we’ve discovered a great source of cost-free clean/distilled water for all the watering needs: the several air conditioning devices, spread throughout the school campus.

Hanging Garden: Making good use of (free!) 6,000 liters of water/year

Wordle: herbsI’ve been asked to provide updates on our Hanging Garden Project. We’ve got new planters, ‘freshly donated seeds’… and a cost-free watering system. For the ones not (yet!) familiar with the ‘mathematics behind getting cost-free water‘, here’s how it works: Our middle/high school students have been deeply involved in building a system with planters made from recycled PET bottles, as seen on the right.

Besides that, we’ve discovered a great source of clean/distilled water for all the watering needs: the several air conditioning devices, spread throughout the school campus. So, the students began collecting the not-before-managed water… But, how could they find out how much water would be “released” by the AC devices?


The answer to that question morphed into a mini-mathematical project: Math students were asked to develop a strategy to evaluate the volume of water released by the AC equipments, write their assumptions down (hourly rate, number of school days, etc), and today presented their results: on average, an AC device is capable of releasing over 6,000 liters of water during the course of a regular school year.

 

 

Way more than enough for keeping the Hanging Garden alive and growing! 😮

Having fun with graduated cylinders & Math!

Let’s see… once more, science and math can definitely be fun (and rewarding!) 😮

So far, we’ve got seedlings of:
Arugula, rocket (Diplotaxis arucoides) [Rúcula, in Portuguese)
Basil (Ocimum basilicum) [Manjericão]
Chamomile (Chamaemelum nobile) [Camomila]
Cherry tomato (Lycopersicom esculentum var.) [Tomate-cajá]
Anise (Agstache foeniculum) [Erva-doce] 
French onion 

Salvia
Spinach
