Unit 1 - What is Water?
Where does the water in our homes come from?
Is it a good idea to drink the water from a pond or a lake? What might be in the pond or the lake that would make the water unsafe to drink?
The water that comes in to our homes has to be cleaned before it is safe for us to drink. The water that we use in our homes also has to be cleaned before it goes back into our rivers and seas.
