Collect water samples from different sources.
Label each bottle with the water source.
Follow the instructions on the hardness test kit to measure hardness levels.
Record the hardness levels for each sample.
Test the pH of each water sample using pH strips.
Compare the results and analyze any patterns.
Research the impact of water hardness on daily life and appliances.
Prepare a report based on findings.
It is expected that the hardness levels will vary across sources, influencing soap lathering and leading to scale buildup in appliances. Data will reveal these differences.

Water hardness refers to the concentration of calcium and magnesium in water.
Hard water can reduce soap effectiveness, leading to soap scum and less lather.
Yes, hard water is safe to drink, but it can affect taste and may cause scale buildup in pipes.
