Details: Investigate the water cycle.
Driving Question: How does the water cycle affect life and the environment?
Recently we have been looking at the water crisis going on in the world and how it affects people trapped in it and how lucky we are to have clean drinkable water piped to our homes.
We watched a video and discussed how would we solve this problem.
We posed a question.
All that water what’s the problem?
Our learners wondered;
I posted a question. How could YOU solve the problem of dirty water using recycled, cheap and available materials?
There was a great deal of discussion including desalination plants and other ideas that when we planned it out were not achievable. Then we looked at who goes hunting? What do you drink in the bush? What can you use to clean the water you get from the stream?
We discussed how could we use the design process and some limited materials to build a water filter.
Ask - Our big question. How could we build a water filter?
Imagine - What would this look like - brainstorm size, materials etc.
Plan - Can we build what we imagined?
Create - Build it, test it.
Improve - What could you do better.
What the students thought about the project.
How can a water filter help the water crisis?
It can save lives by filtering water
It takes out some of the minerals in the dirty water and it saves money so kids can do things.
It can help because people who don’t have clean water can make one then boil the water leftover
It can save the water from being dirty the bad thing though is it doesn’t get rid of the bugs it only gets rid of the poo, bark, and dirt and you have to filter it again and again till it’s clean
We can save water from dirty water to clean water to help our environment stay clean. It takes them 3 hours to get back safely but when they get home the waters always dirty so then people started making filters to give clean water to others that don’t get water.
No, because it only changes the colour but the bacteria in the particles are still in the water.
