Hypothesis 
I believe that out of: tap water, bottled water, filltrated water and water out of Lake Michigan that filltrated water has the least chlorine.
Abstract 
My purpose was to find out what chlorine is, can do to you and which water is safest to drink. 
First I needed all four waters which are: tap water, bottled water, filtrated and water from Lake Michigan. Also, a testing kit 
My conclusion is that all waters seem to have no chlorine.
Materials   
  • Test tubes
  • Testing liquid
  • Filltrated water
  • Lake Michigan water
  • Tap water
  • Bottled water.

Procedure   

I will go to the lake to get my lake water then to the store to get the bottled water and everything else I need is at home. Then I will test them to get my result.
Results   

The water samples had too little chlorine for the test to measure.
Conclusion 

All waters tested had small enough amounts that I could not tell how much chlorine they had.
