AP6456 - $10.60
Improve student results when conducting thermodynamic 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. Their wide, stable...
AP9031 - $15.55
Perform the classic demonstration “thermal expansion of metal” with this ball and ring apparatus. Brass ball passes freely through ring at room temperature but when the ball is heated in a flame, it no longer passes through the ring. Plastic or wooden...
AP9160 - $43.10
A specially insulated outer wall makes this quality calorimeter five times more sensitive than traditional instruments. It is constructed of an aluminum inner cylinder surrounded by a thick layer of styrofoam insulation, then enclosed in a durable...
AP4733 - $14.35
Used to measure the amount of heat generated by an electrical circuit. When an electric current flows through a conductor, some of the electrical energy is converted to heat energy. This heat energy is referred to as joule heat. The greater the resistance...
AP5650 - $7.90
A great introductory demonstration of thermal expansion, large enough to be seen in the back of the room. This bimetallic bar will bend dramatically when heated in a Bunsen burner due to the different thermal expansion rates of each metal used in the...
AP5912 - $38.00
Perform thermodynamics labs faster and less expensively-and obtain better, more precise results! Seven laboratory activities in this manual are traditional thermodynamics experiments. When used with the small-scale calorimeters described below, the...
AP5928 - $15.95
The perfect small-scale calorimeter! These high-quality, 2"-thick polystyrene calorimeters allow for quantitative thermodynamics experiments with only 15 mL of reagents. Smaller amounts provide faster results so several trials can be completed...
AP9212 - $18.20
Investigate how different types of metals conduct heat as you hold the center of the conductometer over a flame. Small amounts of wax placed in wells at the end of each metal rod melt at different rates demonstrating the relative thermal conductivity...
AP6488 - $23.35
Decisively demonstrate heat conductivity in less than 30 seconds! Touch the identical-looking blocks. One feels cold to the touch, the other feels warm. Place an ice cube on each block and watch as one ice cube rapidly melts. Which block melts the...
AP7017 - $108.85
This “series” of four hands-on experiments and one demonstration will provide students with an in-depth understanding of heat, temperature, and heat energy transfer. Students begin by comparing the thermal conductivity of five different metals. They...
AP7115 - $28.15
Teach a variety of physical science concepts with the simplest steam engine. Add water to the flask, insert the rubber stopper with exhaust arms, and hang it securely. Then, use a Bunsen burner to heat the water and watch the engine spin! Illustrates...
AP4679 - $293.90
Determine the coefficient of expansion of four different metals. The dial indicator on this newly engineered linear expansion apparatus will provide more accurate and reproducible results and is more accurate than the old micrometer form. This quality...
AP5713 - $15.55
Dramatic demonstration with only the heat from your hand. Two glass bulbs are connected with a glass tube and contain a colored, volatile liquid. Holding one of the bulbs in your hand causes the liquid to boil causing vapor to move into the other bulb...
AP5784 - $921.85
Measure the radiation left by the warm surface of a human hand pressed on a wooden desktop! This radiometer is sensitive! It will measure the energy in a beam of radiation and is calibrated in Watts per meter. The detector is a thermopile consisting...
AP7113 - $19.10
A new twist to an old classic! Demonstrate both linear and volume expansion and contraction with this simple device. At room temperature, the metal rod fits between the metal bracket and into the drilled-out holes. However, when the metal rod is heated,...
AP9214 - $12.10
Determine the coefficient of expansion of four different metals. The dial indicator on this newly engineered linear expansion apparatus will provide more accurate and reproducible results and is more accurate than the old micrometer form. This quality...
AP9215 - $20.90
Determine the coefficient of expansion of four different metals. The dial indicator on this newly engineered linear expansion apparatus will provide more accurate and reproducible results and is more accurate than the old micrometer form. This quality...
AP9216 - $21.90
Determine the coefficient of expansion of four different metals. The dial indicator on this newly engineered linear expansion apparatus will provide more accurate and reproducible results and is more accurate than the old micrometer form. This quality...
AP9217 - $8.20
Determine the coefficient of expansion of four different metals. The dial indicator on this newly engineered linear expansion apparatus will provide more accurate and reproducible results and is more accurate than the old micrometer form. This quality...
AP4640 - $29.25
The Stirling engine has been marveled at ever since its introduction in 1816. Once your students see this clever model engine in operation they'll be astonished as well! The principles involved are difficult to comprehend, so this very simple model...
AP5718 - $249.90
Need a dramatic introduction for your energy conversion unit? Students are fascinated by a functioning steam engine! Trace all the energy conversions starting with lighting the match, to burning the dry fuel, to converting the water to steam, and finally...
AP6043 - $139.20
Attach this functioning electric generator to a steam engine (AP5718) and amaze your students as you convert steam power to electrical power. The included drive belt is easily attached to the flywheel of the steam engine and starts generating power...
AP9220 - $39.20
Heat up five different metal cylinders to exactly the same temperature, add each to a precise amount of water at known temperature, and observe the water temperature change. What variation! Why? Students perform a lab activity and calculate the specific...
AP4735 - $29.55
This hands-on activity clearly illustrates how a thermostat works by demonstrating differential expansion. Students heat the bimetallic strip in the model and watch it bend to make contact, complete the circuit and light the lightbulb. After the strip...
AP5107 - $346.60
As fossil fuels become more expensive and as we become more aware of their harmful effects on the environment, alternative forms of energy increase in interest. This wind generator is a mini-research unit on wind power and windmill design. The unit...
AP5719 - $79.80
Generate steam in a controlled and safe fashion. This steam generator will not break or rupture since there are no seams. The same aluminum alloy is used throughout to minimize the problem of galvanic corrosion. Use this gas-heated steam generator...
