Answer 1

Idea 1: Hard water is signified by non-lathering or very low lathering of soap.
So, you can compare and contrast the bubbling effect of soft water against that of hard water.
Idea 2: Softening of water can be demonstrated.
Check http://www.lenntech.com/water-softener-FAQ.htm for more information.

Answer 2

Order some rapid biking Brassica rapa from Carolina organic and organic grant or wisconsin rapid plant life. The plant's entire existence cycle is purely 30 days. The seeds will sprout in some days, and are mature in 2 weeks. that's the classical plant sort for botanical analyze.

Answer 3

you could use different kinds of metals to see which one would rust faster in hard water thats what my sister did and she got to go to some science fair thing for the coolest projects
good luck i hate science projects

Hard water is NOT ice it is water with minerals such as salt and magnesium

Above is a high school level experiment still looking...


Hydrophobically associating polymers for oily water clean-up

Above is an interesting idea of breaking up oil in salt water (this may be too advanced I am not sure where you are academically, but if you want a good challenge) I am going to find you one more idea.

Answer 5

Punch regular water with left hand, and hard water with right. Prove that the hard water is hard by comparing the damage to the hands.

Answer 6

hard water as in ice?
i would try.. something about phase changes such as vaporization, metling, and stuff like that. Also show different ways of how the phase changes occur (fire, sunlight...)
