HEAT & THERMODYNAMICS, CONTINUEDIce Melting BlocksDemonstrate heat conductivity with identi-cal-looking blocks—one cold and the other warm. Place ice cubes on each, and one ice cube rapidly melts. The “cold” block melts the ice faster because it is a heat conductor that easily transfers heat energy while the “warm” block is an insulator. The unmistakable discrep-ant event will clarify the difference between a heat conductor and a heat insulator. Instructions provided. Blocks are 10 x 10 cm.AP6488 I $25.75Conduction, Convection and Radiation—Activity-Stations KitStudents discover basic heat transfer princi-ples with hands-on experiments that test the thermal conductivity of different materials, investigate temperature effect on liquid density as convection currents are created, observe the effects of convection currents on a lit candle and explore heat transfer by radiation with temperature increases in sand exposed to heat. Includes comprehensive background information, Teacher Notes and student worksheets.AP7183 I $73.20Up, Up and Away—Hot Air Balloon Student Activity KitStudents construct and launch mini hot air balloons to learn how these balloons lift from the ground, stay aloft and eventually descend. Includes a unique apparatus for safe and successful balloon launches, easy-to-follow instructions and materials needed to construct 15 hot air balloons. A heat gun or propane torch is required and available separately. Includes Flinn Exclusive STEM Integration Guide.AP6310 I $72.40Collapsing Can—Demonstration KitWith over 1,800 lbs of force, this demon-stration convinces students that air exerts significant pressure. Place about a centimeter of water in the bottom of the can, and heat it until it boils and steam comes out of the uncapped top. Remove the can from the heat, cap it tightly and watch and listen to the drama. As the can cools, a vacuum forms inside and the can dramatically collapses. Includes one can and detailed instructions.AP4695 I $12.65Calorimeter, FoamImprove student results when conducting ther-modynamics and heats of reaction experiments. The thick walls and lids make these calorimeters more effective than ordinary foam drinking cups by preventing heat loss in all directions. The wide, stable base prevents tipping when mixing with a magnetic stir bar. Use a sharp knife to cut the foam lid to fit any thermometer. 900 mL capacity. Package of two.AP6456 I $10.05Hand BoilerAmaze students by causing liquid to boil with the touch of your hand. You can even perform a fractional distillation (instructions included) with the Hand Boiler.AP9293 I $8.00
