1. How did the temperatures of the water in the red Solo cup and the water in the bucket compare at the beginning?
2. What happened to the temperature of the cold water over time?
3. What happened to the temperature of the warm water over time?
4. How did your graph show what happened?
5. After 15 minutes, what did you notice about the lines on your graph?
6. What happened to make the temperature of the cold water get warmer?
7. What happened to make the temperature of the warm water get colder?
8. Use your line graph to predict what the temperature of the warm and cold water would be after 10 more minutes. Record your predictions below. Why did you choose these temperatures?
9. Did the water go through the red Solo cup? How do you know? Can the food coloring in the warm water help you explain this answer?
10. Which direction did the heat energy move?
1. There was a 43 degree difference. The red solo cup was warmer.
2. The cold water became warmer. The readon it became warmer because the heat from the hot water went through the cup to the cod water.
3. The warm water became warmer because the cold water was getting warmer because the heat from the cold water was going into the cold water.
4. The graph showed the tempetures decline and go up.
5. The lines on the graph had crossed. They crossed because the heat from the warm had gone into the cold water.
6. The warm waters heat went into the cold water trying to warm it up.
7. The warm from the cold water was going into the cold water. Trying to warm it up.
8. I predict that the warm water will be 55 degrees and the cold water will be at 65 degrees.
9. The warm water didn't go through because there was no red food die in the cold water. The warm food coloring helped because you could see were the warm water was.
10. The heat energy moved down because it was giving it's heat to the warm water.
