Melissa Canales 12/8/11 Period 1

2. RESEARCH
There are four different types of temperature scales that I researched.
The Absolute scale, Fahrenheit scale, Celsius scale, and the Kelvin scale.
The Celsius scale is also known as the Centigrade Temperature Scale.
When a metal passes through the magnetic field, the electrons start to line
up to the electric current, the part of the metal closer to the field
becomes the South Pole and the other end of the magnet becomes the
North Pole.

3. How does a magnet’s temperature affect its strength?
PROBLEM STATEMENT
How does a magnet’s temperature affect its strength?

4. HYPOTHESIS If the magnet’s strength depends on
Its temperature, then I hypothesis that the
cold temperature magnet will have a stronger
magnetic force therefore its strength will
be the strongest out of the rest.

5. INDEPENDENT VARIABLE:
The temperature of the
magnets

6. DEPENDENT VARIABLE The amount of paper clips the
magnets have magnetized

7. CONSTANT
VARIABLES
The time the magnet is left in the freezer and in the boiling water(5 min)
The time for the magnet to collect the paper clips(1 min)
The heater
Type and shape of magnet
Same type of paper clips
Number of paper clips
The timer

8. materials 3 Magnets 1 Freezer 1 Timer 1 heater 12 Paper clips
Safety gloves
A bowl
A dry towel cloth
A tea kettle
Pencil & Paper
materials

9. Put one magnet in the freezer for 5 minutes
PROCEDURES
Grab all materials
Put one magnet in the freezer for 5 minutes
While your waiting for the magnet in the freezer you layout the 12 paper clips on a table
Take the magnet out and start the timer until it reaches 1 minute, during that one minute you collect the paper clips with the magnet
Record how many paper clips the magnet has magnetized, repeat steps 2-5 two more times to get an accurate average.
You grab the tea kettle with water and you boil the water, use your safety gloves to carefully put the water in the bowl
Lay the magnet inside the water and leave it in for 5 minutes, then take the towel cloth and dry the magnet
Then, do steps 4& 5

10. PROCEDURES
9. Grab the room temperature magnet, start collecting the paper clips 10. Record how many paper clips the magnet magnetized, repeat steps 9-10 two more times, then find the average with the magnet until the timer reaches 1 minute

Results
The cold magnet was resulted stronger than the other temperature magnets. The cold magnet resulted with an average of 9.33 , the hot magnet resulted with an average of 7.33, and the room temperature magnet resulted with an average of 7. The warm magnet wasn’t as strong as the cold magnet. Same with the room temperature magnet.

12. CONCLUSION
My hypothesis was correct, the cold temperature magnet’s strength would be the strongest. This experiment would benefit man-kind by using colder magnets to get stronger results. For example: a scientist wanted to test his magnets to find out which can pull a metallic cube from a table, he can use my answer to make his prediction with confidence. Magnets can probably be used in the future to replace glue.
