Heat Transfer: Radiation, Conduction, Convection Sequenced Activities
I put together a series of activities to teach heat transfer. Here they are in Microsoft Word format.
Many of them use liquid crystal thermometer plastic. They are plastic that change color as they change temperature. You've probably seen thermometers that are made this way. You can get them from a few places, but I am big fan of the 12 inch x 12 inch squares from Edmund Optical. They work well and one sheet is enough for a whole class. http://www.edmundoptics.com/testing-targets/calibration-standards/temperature-sensitive-liquid-crystal-sheets/1642
What's great about liquid crystal thermometers is that they require very small temperature changes to have a noticeable change.
Activity 2.01 You have a white index card with a liquid crystal thermometer on the top. Discover what it does when you hold it between a thumb and a finger, let it go and hold it in the air, hold it again and then put the bottom against a table, press your thumb against it while it is on the table.
