Inspiration
United Nation's 6th Sustainable Development Goal
Some communities in the Philippines lack access to safe water.
What it does
- For our turbidity sensor the numbers go up after the sample of water was filtered.
- The light intensity value will be printed on the LCD display (i.e. a value around 200 for the dirty water and after filtration, the value jumps up to 400)
- This difference tells us there are less pollutants in the filtered water, meaning less scattering of light, therefore a higher detected light intensity.
How we built it
- We build our water monitoring system inside a --- shoebox
- Program code is uploaded to print the value onto LCD display
- Using Arduino board, photoresistors, resistors and potentiometer, we are able to detect how much light passed through water
Challenges we ran into
- Finding the materials we needed. One of our group members had to go to a beach to collect sand, gravel, soil, and contaminated water
- We initially wanted to include an extraction portion but realized that since we had to work under time constraints, we needed to narrow our scope down.
- We had to ensure most of our materials were in the $15 CAD budget per kit.
Accomplishments that we're proud of
- Designed a fully working prototype with the limited access to materials.
- Our team's initial pitch received a warm welcome from the judges.
- Our team managed to quickly gel together and combine our individual contributions while learning from one another along the way.
What we learned
- Grade 11/ 12 Curriculum in the Philippines
- that the Philippines has low-resource communities that need our help, and it only takes two weekends or even one and a bunch of driven people to help solve small problems and eventually eradicate the bigger ones too
- Revised many previously learnt physical chemistry materials.
- Skills like leadership, teamwork, effective communication by working with each other and attending the scheduled workshops.
What's next for sus educators
- We would love to have our educational kit deployed in a real-world environment with Pueblo Science.
- This could mean at U of T's next Science Rendezvous or a Let's Talk Science Outreach Workshop.
