Scientific Method Review

You and your friend are walking along a beach in Maine on January 15, at 8:00 AM.

You notice that there is melting snow on the roof of the building and icicles hanging from it.

You answer, “I think that the salt in the sea water keeps it from freezing at 21°C.”

You further notice a pool of sea water in the sand near the ocean.

You notice a thermometer on a nearby building that reads 21°C.

You state “How come the water on the roof is frozen and the sea water is not?”

“I’m going to get fresh water and salt water then place both at 21°C to see what happens."

You go on to say, “I think under the same conditions, the same thing will happen tomorrow.”
