3 Hot Nail Lab: Inquiry Version MISSION: Determine the temperature of a Bunsen burner flame without sticking a thermometer in it. METHOD: Heat up a nail in the flame, drop it in water... you figure out the rest. Discuss your materials & procedure with your table group for 10 minutes! What materials did your groups determine they’d need tomorrow? Is there any non-physical equipment you’ll need to accomplish your mission? What are you NOT going to do with the thermometer tomorrow?

4 Purpose Materials Procedure Data Conclusions

5 What follows is what Barnes calls the “Where can we go from here?” method of problem-solving.

6 When we finished doing the procedure with the materials, what data did we have at that point? m water, m nail, T i-water, T f-water, T f-nail, C p-water, C p-nail What new information can we calculate based on that data? How? We can subtract T i-water from T f-water to get  T water We use the equation  T = T f – T i What new information can we calculate based on those new results? How? Q = m  T C p, so we can calculate Q water... measuredbook/www

7 What follows is what Barnes calls the “How can I accomplish my mission?” method of problem-solving.

8 1. What am I trying to find out? What is my mission? 2. What tool(s) do I need to get that? 3. How do I use the tool? 4. Use the tool(s) 5. Eat the banana.
