This is the brainstorming that we did together in class. If you find it helpful, you can fill out the causes, solutions, and terms with your own water hardness subtopic to bring clarity to research.

------------------------

Topic: Water Hardness

Causes - cosmetics, manufacturing, natural minerals, ph balance

Solutions - carbon filters, descaling, filtration 

Remember to think of synonyms & like terms to help with your research. If your original search terms, don't work, use a synonym or like term!
