Activity 3 Response: As an investigation of scientific question B, consider an object that is not the human body, but that also has a consistently higher temperature than the environment. Based on your results from activity 2, describe how you would expect its thermal energy and temperature to change with time. How is it able to stay at a hotter temperature than the surroundings, even though heat is constantly flowing? Given that energy is conserved when considering an entire system, what is the energy flow process throughout the entire system that allows the hot object to stay hot? Now, relate this to the temperature measurements taken of the human body, and explain how our human body is able to consistently maintain a hotter temperature than the environment. Temperature (C) (F) Before 32.1 89.7 rubbing hand After rubbing 34.9 94.8 hand Time 46 seconds After amount 32.1 89.8 of time Activity 4 Response: Use either a human body, electronic devices, and/or light bulbs to capture two (2) images with the FLIR device that each indicate a difference in temperature between two or more objects. Capture the FLIR images with your phone camera and paste them here. For each image: Describe the heat flow between different objects visible, and indicate how these temperature differences were created and/or maintained by energy changing forms. Label the hottest/coolest objects in your images.
