4A30.10 Click for full description Bimetalic Strip This demonstration shows the thermal properities (thermal expansion) of two diffrent metals.
4A30.20 Click for full description Ball and Ring This demonstration shows the thermal properties (thermal expansion) of metal. One set has a ball that fits through the ring at room temperature, and the other has a ball that does not fit through at room temperature.
4A40.30a Click for full description Smashing Rose This demonstration shows that the physical properties of an object may change when cooled. This can also be done with a fruit (see 4A40.30b).
4A40.30b Click for full description Smashing Fruit This demonstration shows how the properities of fruit change at low temperatures. This can also be done with a flower (see 4A40.30a).
4B20.10 Click for full description Convection Tube This demonstration shows convection currents.
4B30.10 Click for full description Rate of conduction (dropping balls) This illustrates different material's rate of conduction.
4B40.10 Click for full description Light a Match This demonstration visually shows that a mirror can focus Infrared waves at the focal point.
4B50.60 Click for full description Greenhouse Effect By using a computer and digital display thermometer, you can show the class that equilibrium temperature increases when the thermocouple is encased in a plastic bottle, and then increases again when water vapor (a greenhouse gas) is present inside the bottle.
4B70.10 Click for full description Fire Syringe This demonstration shows the relationship between Pressure, Volume, and Temperature in an adiabatic compression.
4C20.20 Click for full description Ice Bomb This demonstration illustrates a decrease in density when a liquid undergoes a phase change to a solid.
4C30.35 Click for full description LN2 Bomb This demo shows what happens when LN2 warms up inside a closed container.
4C32.10 Click for full description Sling Psychrometer Use a commercial sling psychrometer to determine relative humidity. Two thermometers, one with a wet wick, are mounted on a device swung around the head.
4C50.20 Click for full description Critical Opalescence This apparatus is used to illustrate critical opalescence near the critical point.
4D20.10 Click for full description Crookes' Radiometer This demonstration shows a crookes' Radiometer.
4E10.15 Click for full description Balloon on a Flask This demonstration shows that the pressure increases as water is heated up and changed to steam.
4E10.20 Click for full description Balloon in LN2 This demonstration shows what happens when an air filled balloon is placed in LN2. When the balloon cools down, the pressure decreases and is compressed by atmospheric pressure.
4E10.25 Click for full description Crush the Can (Thermo method) Crush the can using the principles of thermodynamics.
4E10.40 Click for full description Hot Air Balloon Hot air rises!
4E20.25 Click for full description Boyle's law apparatus This apparatus is used on the overhead. There are two ways to use this.
First, you can connect it to the syringe and view what happens when you change volume.
You can also connect it to the ball and change its temperature by cooling it in LN2.
4E20.40 Click for full description Balloon In Vacuum This demonstration shows what happens to the volume of a balloon when pressure is reduced.
4F30.01 Click for full description Hero's Engine This demonstraion uses a hero's engine to illustrate that with increased temperature and constant volume, the increase in pressure causes the steam to escape.
4F30.10 Click for full description Sterling Engine This demonstration shows that a sterling engine operates simply by heating one end. A description of how the sterling engine operates can be included here.
4F50.12 Click for full description Thermoelectric Fan (Peltier) By keeping the plates of a peltier at different temperatures, a current is produced to run the fan.
