Scientists and Problem Solvers of the Future
DEFINE
Our group of three was challenged to discover a problem and create a way to fix it using our scientific knowledge about technology.
So right away, we got to work and started thinking long and hard.
DISCOVER
We started our discovery process with a brainstorm of possible issues we could attempt to solve. Some big categories we though of are pollution, floods, wildfires, quality of health, decision making, exercise, natural disasters, and sleep scheduling.
As we looked more into the ideas, and expanded them into more precise problems. We found ourselves being able to eliminate problems that are already solved or that are much out of our capabilities to solve. The big category we ended up choosing is pollution which led us to decide to help our quality of water.
DREAM
We put on our thinking caps and started thinking about what we can do to help improve our water quality. We remembered all the different aspects and characteristics of water quality that we learned in the previous unit and used that knowledge to help us out. With our current abilities, we thought to to program a micro: bit to be able to test the turbidity, temperature, speed, and pH levels of the water. Ideally, the micro: bit would sit in water and would be sophisticatedly programmed, but we got pretty close to our ideal idea.
DELIVER
We were able to code our micro: bit to be able to use its sensor to detect the level of light, which allows us to see levels of turbidity in the water. We also used the temperature sensor to signal the temperature in the water and notice any changes. Another sensor we used was the acceleration which lets us know the speed of which the water is going. We also wanted to be able to find the pH level, but that was out of our reach of knowledge and sources however, we were able to find a video that explains how to create a pH sensor.
