Electricity and Magnetism Standards
S5P2. Obtain, evaluate, and communicate information to investigate electricity.
a. Obtain and combine information from multiple sources to explain the difference between naturally occurring electricity (static) and human-harnessed electricity.
b. Design a complete, simple electric circuit, and explain all necessary components.
c. Plan and carry out investigations on common materials to determine if they are insulators or conductors of electricity.
S5P3. Obtain, evaluate, and communicate information about magnetism and its relationship to electricity.
a. Construct an argument based on experimental evidence to communicate the differences in function and purpose of an electromagnet and a magnet. (Clarification statement: Function is limited to understanding temporary and permanent magnetism.)

Static Electricity
What is Static Electricity?
Here are a few things to remember about static electricity:
DO NOT ATTEMPT TO DO THESE SCIENCE TRICKS UNLESS you have your parent's permission to do so. Parents should supervise.

Vocabulary Words
circuit: complete path an electrical current flows through conductor: substance which allows heat, electricity, or sound to travel through electromagnet: temporary magnet formed when electricity flows through coiled wire electron: negative charged tiny particle found in the electron cloud of an atom insulator: substance which does not allow heat, electricity, or sound to travel through neutron: neutral charged tiny particle found in the nucleus of the atom proton: positive charged tiny particle found in the nucleus of the atom |
BACKGROUND INFORMATION
If you charge two balloons by rubbing them on your clothing, numerous negative charges will be created. The balloons will repel each other because of the number of negative charges. If one balloon is negatively charged and you have pepper on a plate, the pepper will jump towards the balloon because it has a positive charge and the opposites attract. This is a kind of electricity-static electricity. Molecules are the smallest bit of a substance. Atoms are made of protons, neutrons, and electrons. Moving electrons create electricity. The ability of the electrons to move freely allows for energy to form and work to be done. Electricity will only flow when a circuit is complete. Metals are the best conductors of electricity, offering the ability for the current to flow easily. Copper is the most widely used conductor for wiring. Insulators are “poor conductors” of electricity. Electricity and magnetism are closely related. Both have a magnetic field in which electrons flow. Bar magnets attract objects most strongly at their poles (the ends). The magnetic attraction weakens towards the middle of the bar magnet, offering little to no magnetic attraction power. Electromagnets are created by wrapping insulated wire around a nail and connecting both ends of the wire to the battery. The electrical current flows through the coiled wire, charging the nail. This nail is then magnetized and will remain a strong magnetic force as long as the electrical current flows. When the electrical current is broken, the nail is no longer considered a magnet. |
