- The water in the red Solo cup was 30.6 degrees** warmer than the water in the bucket at the beginning of the experiment, and 1.4 degrees** warmer than the water in the bucket at the end of the experiment.
- The temperature of the cold water started at 37.6 degrees* and ended at 48.5 degrees*, so the temperature went up 11.9 degrees**in 15 minutes.
- The temperature of the warm water started at 68.2 degrees* and ended at 50.9 degrees*, so it got 17.3 degrees** cooler in 15 minutes.
- The graph shows what happened by showing us how the hot water started out near the 70 degree mark on the graph, and then going down to just above the 50 degree mark, and showing how the cold water started about at the 40 degree mark on the graph and went higher until it was just below the 50 degree mark.
- After 15 minutes, I noticed that the lines on the graph were about ready to cross, and probably, they would if the data had been recorded longer.
- The cold water got warmer because the hot water inside the cup was heating it up, and the air around it wasn't as cold as it was.
- The warm water got cooler because the cold water surrounding it was cooling it down, and the air around it wasn't as hot as it was.
- My predictions of the temperatures of the warm and cold water after 20 minutes are 50.5 degrees for the warm water and 53 degrees for the cold water because the hot water looked like it wasn't going down towards the end, and I thought that it looked like about 50.5 degrees. Also, I thought the cold water seemed to be going up at a pretty constant rate of about 5 degrees for most of the experiment, and it looks like it would be at about 50 degrees if it continued at this constant rate.
- The red food coloring in the warm water didn't help me understand how heat energy is transferred because the red food coloring was not in the cold water at the end of the experiment. Also, it doesn't make sense how the water would get from the cup into the bucket, so I'm actually a little bit confused by it.
