Artec"s Peltier Device Experiment Kit is a great device that confirms and teaches the concept of the Peltier Effect. A Peltier device is an electrical device that transfers heat when an electric current is applied to it. These devices are commonly found in refrigerators. When one side of the device heats up, the other side cools. The Peltier Device Experiment Kit shows both the Peltier Effect and the Seebeck Effect (electricity is generated by applying temperature to the front and back of the device). This device is an excellent source of hands-on learning!Peltier Device Experiment Kit contents:1- Peltier device1- Heat sink1- Transparent case1- Aluminum dish1- Instruction manualArtec"s line of science educational supplies for classrooms are a great source for STEM (Science, Technology, Engineering, and Mathematics) education and curriculum development for elementary, middle, and high schools.
