Title: Radiation Lab
Question: Does the color of objects affect the amount of energy transferred by radiation?
Hypothesis:

Mar 197:45 AM
Analysis:1. How does the temperature of the two cans compare at the start of the experiment?2. How does the temperature of the two cans compare at the end of the experiment?3. Describe the change in temperature of each can.
Conclusion: How does the color of an object affect the amount of energy transferred by radiation?

Analysis:
1. What is the relationship between the time it took each paper clip to fall and the location of theclip on the wire in respect to the candle?
2. What can you infer about how heat moved from one end of the wire to the other?

Conduction Wheel Races
Question: How can you determine which type of metal is a better conductor?
Hypothesis:Metal type Time to drop
Aluminum
Steel
Stainless Steel
Copper
Brass
Mar 197:45 AM
Analysis:
1. How would you rank the metals from best to worst conductor of heat?
2. The denser metals are better conductors of heat. Infer which metal is the most dense and which is the least dense.
3. Why would a denser metal be a better conductor?

Convection Tube
Question: How does water move when heated?
Hypothesis:
Data: Draw pictures at each step:1. Before adding heat2. One minute after heating3. Three minutes after heating4. Five minutes after heating
Oct 258:29 AM
Analysis:
1. What was the source of heat?2. Was heat added or taken away from this experiment?3. The flame heated the glass and then the glass heated the water inside the tube. What type of heat transfer is this?4. The warm water in the tube started to expand and mix with the cold water. What type of heat transfer is this?5. Why was the food coloring added to the water?6. Did the food coloring move toward or away from the heat source?7. Did the heated water become more or less dense?8. Why did the dye move away from the heat source?
