Slide 2: What is electricity?
Electricity What is electricity? Electricity is the movement of electrons. Every single item in the whole world is made up of tiny, tiny things called atoms. Electrons are inside each of these tiny atoms circling around the nucleus. What items in your classroom use electricity? September 1, 2015 ©20
Slide 3: Electrons
Electrons What type of a charge do electrons have? Electrons have a negative charge. Most electrons stay inside their own atoms, but sometimes they leave one atom and jump to the next. This is because their negative charge causes electrons to push away from, or repel, each other. Electrons the
Slide 4: Current
Current What does the word current mean? A current is defined as something that flows. You have probably observed water current in a river or stream. The flow of electrons through conductive material is known as an electric current. September 1, 2015 ©2012 Micron Foundation, Inc. | 4
Slide 5: Water Analogy
Water Analogy ▶ Voltage is the difference in charge between two points, or the amount of potential energy. In our water analogy, the height of the tube in relation to the water level in the bottle, or the potential energy to push the water out, is like voltage. ▶ Current is the flow of electrons t
Slide 6: Conductivity
Conductivity ▶ What does it mean for a material to be conductive? It means that current runs through the material easily. The electrons are loosely bound. ▶ Materials that conduct electricity are called Conductors ▶ What types of materials are good conductors? Gold, copper, aluminum, or other me
