It’s the thing that I can’t live without!This is the water filter that I made in science class.
The challenge is to make a water filter to survive on an island.
I think engineering is important because you can make things to make life easier.
I design this water filter because I searched for water filters online. It worked pretty well. I will remove the sand and add another layer of cotton balls if I could do this again.
Our challenge is that the water filter is not doing anything.
Material used:
-cloth
-little rocks
-sand
-tape
-plastic bottle
-screen
