Environmentalist: Drinkable Water for All

A group of students in Ethiopia is in need of a portable water filtration system so that they can have access to clean water on their journey to and from school. In this adventure, students will create this portable system using art supplies and building materials, test its effectiveness, and make sure the design is repeatable.

    In step 3 it states that “each explorer will take 1/2 cup of the polluted water and pour it into the open end of the bottle and let the water run through.” After watching the video in the Discovery Link, I am wondering if you want them to copy that same filter system that is demonstrated in that video? If not then how is water to “run through” the water bottle? There are no instructions regarding how to make the system or poke a hole in the water bottle, etc…In step 2 it says to give kids an empty water bottle and then just let them figure out a system?

    Also, it would be much more convenient to just click on one “button” and open up all the docs that need to be printed out, rather than click on 6 buttons and print out separately.

      Hi Anna!

      Students should create a filtration system based on the criteria (ex: have a filter on top of the water bottle). They do not have to design their filtration system identical to the one in the video. Instead, they should follow the criteria and sketch out their own ideas. The only requirements are that they should have an opening at the top of their water bottle that will be a filter, have a way to filter for objects like pebbles, and have a strap to carry the filtration system. We encourage students to use their imaginations and ideas when designing!

      We will definitely take into account feedback surroundings buttons. We find that some teachers like having separate buttons if they are showing pictures and handouts on a smart board, which is why we made the buttons separate 🙂 We will definitely make a note- we appreciate all feedback!

    I ordered materials so the students can create this at home during the lesson. I’m excited to see what they will design:)
