How do certain liquids affect magnetism?
Materials
72 GTC standard paperclips
1 cup of regular Coca-Cola
1 cup of 91% rubbing alcohol
1 cup of tap water
One 1 x 1/8 Neodymium magnet
Measuring cup
3 transparent glass jars
Introduction
I chose this project because I wondered how certain liquids could affect magnetism. Also, if we ever dropped an important material into the ocean, or a lake, and it was too heavy to lift, we could use magnetism, and get it out safely.
Hypothesis
If I test the magnetism with water, then the magnetism will be the strongest.
Variables
Dependent: Amount of paperclips that are attracted to the magnet,and stick to it.

Independent:Testing the magnetism with different liquids.

Control: Amount of paperclips, amount of each liquid used, and type of magnet.
Procedures

Fill 1 cup with tap water, 1 cup with alcohol, and another 1 cup with Coca-Cola
Pour each liquid into a glass jar
Place 8 GTC standard paperclips into each jar
( Let all paperclips settle to the bottom of the jar)
Hold magnet out to each jar, only letting the magnet touch the glass for 5 minutes, or until all of the paperclips are stuck to the magnet.
Slowly, and carefully, slide the magnet up, ( Still touching the glass jar) and count how many paperclips stuck to the magnet.
record data
Data
Test 1:
Coca-Cola: All paperclips were attracted to magnet, they reacted quickly.
Water: All paperclips were attracted to magnet.
Alcohol: All paperclips were attracted to magnet, reacted slowly.
Test 2:
Coca-Cola: All paperclips were attracted to magnet, they reacted quickly.
Water: 7 paperclips were attracted to the magnet.
Alcohol: 4 paperclips were attracted to the magnet, they reacted slowly.
Test 3:
Coca-Cola:All paperclips were attracted to magnet, they reacted quickly.
Water: 5 paperclips attracted to the magnet
Alcohol: 4 paperclips were attracted to the magnet, they reacted slowly.
Analysis
During my first test, all of the paperclips stuck to the magnet when I tested it with water, alcohol, and Coca-Cola, but it took longer for the paperclips to react when I tested it with the alcohol. Also, when I tested the magnetism with Coca-Cola, the paperclips reacted quickly.
During the second test, only 7 paperclips stuck to the magnet when I tested it with water, 4 paperclips stuck to the magnet when I tested it with alcohol (They reacted slowly),and all of the paperclips stuck to the magnet when I tested it with Coca-Cola (They reacted quickly).
In my final test, only 5 paperclips stuck to the magnet when I tested it with water, 4 paperclips stuck to the magnet when I tested it with alcohol (They reacted slowly), and all of the paperclips stuck to the magnet when I tested it with Coca-Cola (They reacted quickly).
Conclusion
My hypothesis was incorrect because the magnetism was not the strongest with water. However, it was the strongest with Coca-Cola.If I ever did this experiment again, I would probably use different liquids, different magnets, and/or different liquid temperatures.
