Add engineering, design, and creative appeal to your electrical circuits lesson Blend design and technology while drawing a 'liquid wire' circuit. Nontoxic water-soluble paint provides a new way to engage in electronics. Paint dries at room temperature and is suitable as a cold solder. Teach resistance, circuitry, polarity, or voltage in a fun, creative way. Works with electrical components, prototyping materials, PCBs, microcontrollers, e-textiles, and conductive thread. Includes application and storing instructions, but no lab activities. Use paint within 6 months of opening. Remove from most surfaces using soap and water. Circuit components such as LEDs, alligator clips, transistors, meters, batteries, or power source (up to 12-V DC) are sold separately. The thinner the layer of paint the faster it dries. Also, conductivity increases as the paint dries. Allow drying time before testing projects. Surface resistivity is approximately 55 _/sq at 50 ' layer thickness. Only available in black but retains its properties even if coated with another material. This creates a great opportunity for exploiting its material characteristics by using it as a graphical element alongside other colors. Helps you teach the following Next Generation Science Standards Student Performance Expectations: Energy Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents. (4-PS3-2) Apply scientific ideas to design, test, and refine a device that converts energy from one form to another. (4-PS3-4) Conservation of Energy and Energy Transfer (PS3.B) Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy. (4-PS3-2, 4-PS3-4)
