My Materials were a plastic bowl, standard #1 paper clips, containers to hold ice and dry ice, small pot for boiling water, thermometer, and 4 magnets. My methods were that first I got the pot and the plastic containers.
Second, I put water into the pot, and ice and dry ice into the plastic containers. Next, I put the water to boil and started putting a magnet in each container and pot, i left one magnet in room temperature.
After, I got a plastic bowl and put 200 paper clips in it. Then, after 10 minutes had past I took each magnet out from each obstacle and put each magnet in the plastic bowl(full of paper clips)for 2 seconds. Finally, I counted how many paper clips each magnet had for each trial. (4 trials)
