Is Ice really clean?

By Freya Young

Purpose Statement

The purpose of this experiment is to see if ice is clean. I became interested in this experiment because people get sick all the time after eating ice and i wanted to know why.The information gained from this experiment will help others by knowing if they can get sick by eating ice.


Research

Ice can get people sick as much as food. For instance, there is mold in ice and it is found most of the time in ice bags. Mold does not just get on the ice in bags, but also at home in your own freezer. Some people believe that the water makes people sick. It is actually the ice because when the water freezes all the bacteria goes straight into the middle.


Ice can get people sick just as much as food can. Ice is even dirter than toilet water. Seventy percent of the time, ice from fast food restaurants was dirtier than toilet water. They tested the ice and it was positive for E.coli bacteria. It comes from humans waste. Ice is likely dirtier because machines aren't cleaned. People also use unwashed hands to scoop ice.

Hypothesis

My hypothesis is that all of the ice will be dirty. I base my hypothesis on what I found out in my background research.


Materials

cheese cloth

Ice from 4 different sources

12 rubber bands

12 cups



IV- Ice

DV- Dirt

CV- Cups

CV- Ice

Procedures

1. Get ice from the following places: Teacher work room freezer, fridge from my home and Rath’s Mini Mart.

2. Put cheese cloth over top rim of any kind of cup and secure with rubber band.

3. Place some of the ice from one of the locations on the cheese cloth.

4. Let ice melt.

5. Examine the cheese cloth to see if the ice left any particles on cheese cloth, and record the information in a data chart.

6. Repeat steps 2-5 two more times with more ice from the same location.

7. Repeat steps 2-6 with ice from the other 2 locations.

Results

The origanal purpose of this experiment was to see the purpose of this experiment if ice is clean.The results of the experiment was that the teacher's work room had the most dirty stuff in the ice

Conclusion

My Hypothesis is that all of the ice will be dirty. From back round reserach i always wonderd if the ice was dirty.The results indicate that this hypothesis should be considered correct and the teachers work room is the dirtiest so please do not use that for your safety. Based on the results of this experiment all of my ice was dirty. If I were to conduct this science fair project again I would take results on more ice.
