Science Snippet: Build your content knowledge to help answer youth's questions.
Replay the Special Report video from 3:25 to 4:05 to remind youth of how pipes deliver water to and from different areas.
Science Reflection
Today we engineered a process to filter a limited amount of water so it could be reused for different purposes.
Key Take Away
When water is limited, it can be filtered to remove contaminants/improve quality so it can be reused for different purposes.
Did you know?
Many buildings around the world are already piped to use reclaimed water in toilets. Reclaimed means that waste water has been treated or filtered for reuse.
