Each lab comes with a portable table top work station, step by step instructions, explanations, theory and assessments. The supplied curriculum is student friendly and geared for general education not vocational study. This trainer offers children, grades 6-12, the opportunity to see into the walls of their home and discover how electrical energy is supplied for their use. Help your students solve the mystery of: Where does electricity come from? How does it get into our home? How is electricity distributed through the home? How do we make electrical energy safe? and How are circuits created? Using KELVIN®’s EXCLUSIVE proprietary low voltage DC system, students will safely wire AC components (such as outlets, switches, breakers, a dimmer switch, light fixture and a ceiling fan) for practice with DC voltage. 841890 Assembled Trainer ...... $895
