My favourite subject

Writing is my favourite subject because sometimes you get to make up your own story and put your own character in it.
I enjoy doing this subject because it lets me imagine everything that I put in my story.I also enjoy it because it lets my brain think harder.

Question:
What is the different between hard and soft water?

Introduction:
To determine the difference between hard and soft water by mimicking hard and soft water conditions.

Hypothesis:

I think that water with a high mineral count consisting mostly of calcium, magnesium, and other dissolved compounds, is "hard water".

Additional information:

Water with a high mineral count consisting mostly of calcium, magnesium, and other dissolved compounds, is "hard water". Calcium usually gets into the water in the form of chalk or limestone. Dolomite is usually the predominant source of magnesium found in hard water.
One way to determine if your water is hard is to check how it lathers. When mixed with soap, hard water will have a difficult time lathering. In contrast, soft water will lather / froth easily.

Required materials:

* 2 empty soda bottles of the same size with caps (20 oz kind)
* Epsom salts
* Dishwashing liquid
* Water

Estimated Experiment Time:
Less then 10 minutes

Step-By-Step Procedure:

* 1. Add two cups of water to each soda bottle.
* 2. Add two teaspoons of Epsom salts to one of the bottles. Screw the cap onto the bottle and shake vigorously for a for a few second
* 3. Open the bottles by removing the caps. Add a few drops of dishwashing detergent to each bottle. Replace the bottle caps. Shake both bottle vigorously for a few seconds.
* 4. What do you notice happens?

Observation:

Can you think of other minerals you can add to the bottle of water to make it hard? What do you think you can add in addition to the detergent to make the water soft?

Result:

The bottle with the Epsom salts have far less bubbles than the bottle without Epsom salts. This is because you made the water "hard". Water in many areas is hard because it has minerals dissolved in it. These minerals interfere with the action of detergents. Chemicals can be added to hard water to make it "soft" again, so the detergents can do their job.

Conclusion:
When we put Emsop salt and dish washing liquor into one of the bottles it was very easy to shake and it had less bubble,but when we put dish washing liquor into the other bottle it was hard to shake and it had more bubbles.
