Summary
Water quality and contamination are studied through lab tests on tap and bottled water. Students learn about the presence of various chemical compounds in these water sources.
Hypothesis and Testing
A hypothesis is developed about which water sources will contain the most and least contaminants. The hypothesis is tested by measuring levels of different chemical compounds in tap and bottled water.
Test Results and Analysis
Results from tests for ammonia, chloride, alkalinity, chlorine, hardness, phosphate, iron, and pH are presented. The results are analyzed to determine if bottled water offers health benefits over tap water.
Health Concerns and Cost
The health implications of the test results are discussed. The value of bottled water is considered based on the experimental findings.
Fact Sheets and References
Fact sheets provide background information on the tested compounds. References are given for further reading on water quality and contamination.
Key terms
- Alkalinity
- The capacity of water to neutralize acids.
- Chlorine
- A chemical used to disinfect water.
- Hardness
- The amount of dissolved calcium and magnesium in water.
- Phosphate
- A chemical compound often found in fertilizers and detergents.
- pH
- A measure of how acidic or basic water is.
- Iron
- A metal that can be present in water, affecting its taste and color.
