Even though the modern electric utility industry didn’t begin until the late 1800s, we have been fascinated by electricity since our ancestors first witnessed lightning. So here are a few ideas for projects. The simplest experiment with electricity might be an exploration of conductors versus insulators. A conductor is simply a material through which electricity will flow with little resistance; an insulator prevents electricity from flowing. This can be tested by creating a simple circuit with a battery and a light bulb. If a material completes the circuit, the light bulb will luminesce, indicating that it is a conductor. Most metals are conductors, while most nonmetals are insulators. Therefore, it will not be a surprise to see that silver and copper are conductors, while cotton and glass are insulators. However, you may be surprised by the results of lead (a metal) or graphite (a non-metal). Epoxy molding engineering plastics mainly … Read the rest

The health risks of GMO food are hotly debated, but there is significant evidence to suggest that they may pose a health risk. Although any risks are likely to fall short of the kind of doomsday scenarios being considered here, it is not impossible. Virtual graveyards” have now appeared online. Visitors from anywhere around the world can visit a memorial to a deceased loved one in virtual reality. These memorials can include pictures, video, audio and virtual reality simulations of the deceased person. Some people predict that virtual graveyards will replace real graveyards in … Read the rest
