Why does hot water in a cup get colder over time? Where does the heat go? Can this be prevented? In this lab activity, you will design, construct, and test a device that minimizes the transfer of thermal energy. Your challenge is to design a cup that will prevent the transfer of thermal energy (i.e., heat loss). You must be able to drink from the cup. For one design, you may only use three materials to modify the cup. For the second design, you may use as many materials as you wish. If you need help with materials, reach out to your teacher. Modifications can be made. Materials · hot water · paper cups, large (3) · stopwatch (or timer from your computer or on phone) · thermometer Suggested Materials Note: For suggested materials, you can use anything you have that you think will work! · aluminum foil · bubble wrap · cotton balls · masking tape or duct tape · packing peanuts · paper · sand · styrofoam · tissues or tissue paper · wool or argyle sock · yarn Procedure 1. Plan, design, and sketch or describe two ideas for a cup that prevents heat loss. You can use the materials listed or any others that you have available. 2. Construct your modifications on two different cups using your design plan. Cup 1 will remain unchanged with just hot water as a control. 3. Add hot, not boiling, water to your insulated cups. Record the starting temperature of both cups immediately. 4. Start the timer and record the temperature every minute for 10 minutes. Note: If you are not seeing the temperature drop, you may choose to continue for an additional 5 minutes. Check out this video to learn more about how to set up and carry out your investigation. Data Record your data appropriately for your investigation. Make sure to explain how you modified cup 2 and 3.
