WATER FILTRATION SCIENTIFIC INVESTIGATION… MRS. T. SEYMORE SCIENCE PERIOD 5 TITLE PAGE

PROBLEM Are some minerals in water too big to be filtered out? Are pathogens completely removed after filtering water?

HYPOTHESIS I hypothesize that …… (An educated explanation that can be tested.)

RESEARCH 3 – 5 SLIDES Information about: -Contents in water -Pathogens in water -Minerals in water -Good & bad contents in water -Most important materials that needs to be removed from the water.

HARDNESS The amount of calcium and magnesium that is dissolved in waters result in the hardness of the water. To have hard water, this affects your health, the taste of certain foods or liquids that contain hard water.
