Heat Saver Contest Reminder

Hi All,

Just a reminder that your heat saver device is due this Wednesday, January 23rd.  The project is worth 20 points; here is the point breakdown:

12 points: Report (you do not need to include standards or a group number)
5 points: Your device meets the specified criteria (fits through 50cm hoop, holds 250ml water, etc.)
3 points: How well your device minimizes heat loss (top 1/3 of the class gets 3 points, next 1/3 2 points, etc.)

Please include the following text at the end of your report.  You will fill in the numbers in class.  Have your report completed before class on Wednesday, as you will have minimal time to work on it in class.

Initial Temperature (T_i)             ________°C
Final Temperature (T_f)             ________°C
Change in Temperature (ΔT)  ________°C
Heat Lost (Q = mcΔT)             ________Joules

Thanks in advance for your hard work!
