I need to know this for my homework so if you could just tell me, that would be great. I'm trying to find out how do we know and measure how fast the ice melts.

You have a funnel in the bottom of the container and you measure the volume of water that runs out.
This stuff was invented by a French guy, Antoine Lavoisier. He wrote a book, and you can still get it, probably in your local library.

MELTING SNOW AND ICE: Ice and snow reflect 40 to 60 percent of the sun’s incoming rays. This has the effect of cooling the planet. But as rising temperatures cause ice and snow to melt, the darker land or water underneath will absorb more heat. This could amplify the greenhouse effect, perhaps by 10 to 20 percent.
The Nature Bulletin states: “The strangest and perhaps the most important property [of ice] is that water expands as it freezes
. If . . . water contracted and became denser as it solidified, ice would be heavier than water and sink to the bottom. More ice would form on the surface until the pond was frozen solid. . . . In the cooler parts of the world the rivers, ponds, lakes, and even the oceans would all be permanently frozen.”
How thankful we can be that bodies of water do not freeze solid! And we certainly are grateful that as Jehovah’s handiwork, rain and dew invigorate the earth’s vegetation
