Teacher Tip:George offered a suggestion for a similar apparatus using the clear plastic trays used under flowerpots. These can be supported by Styrofoam cups cut to height and the temperature differences are created by hot water in one cup under one end of the tray (touching it) and icy water in a cup under the other. |
