Problem- Separate a mechanical mixture.
Material and apparatus
I thought the filter would get dirty and the water wouldn’t change.
- Dirty, brown water; grass floating; swirling liquid; sand at the bottom of beaker
In this experiment, the filtering of the dirty water made the water less dirty.
I learned that dirty water could be filtered to be kind of clean again. I might not ever need to use this information but it was cool to learn.
What did you find out:
- The water got dirty, The filter caught the grass.
- We could see multiple things in a mixture and a filter will separate some of these things.
