STATIC ELECTRICITY WB P.62 STATIC ELECTRICITY Above the title on WB p. 62 write the following: Static electricity accumulated on an object to form an electric charge Charges are stationary  which means static electricity does NOT move through wires Examples: Lightning during thunderstorms Static cling when emptying the dryer RECALL: ATOMS Matter is made up of atoms. The atom is made up of: protons, electrons, and neutrons. Most of the mass of an atom and the positively charged proton are found in the nucleus. Moving around the nucleus are very small negatively charged RECALL: ATOMS The total negative charge in the electron is equal to the total positive charge on the protons. All objects normally contain the same number of protons and electrons, therefore they are neutral (uncharged). STATIC ELECTRICITY An object that has extra electrons is negatively charged. An object that is short electrons is positively charged. (EXAMPLE) Determine whether the materials in the following images are electrically neutral, positively charged or negatively charged. STATIC ELECTRICITY How are electrons transferred from one object to another? Protons DO NOT In an atom, the protons and neutrons inside the nucleus MOVE! cannot move. Only the electrons are able to move. STATIC ELECTRICITY When different materials are rubbed together or bump into each other a lot, electrons leave one surface and collect on the other Let’s draw this scenario Examples: together! Socks rubbing against the carpet STATIC ELECTRICITY Substances through which electrons can easily move are called conductors. Eg. metals STATIC ELECTRICITY Substances through which electrons cannot easily move are called insulators. Eg. Non-metals BILL NYE THE SCIENCE GUY – STATIC ELECTRICITY FILL IN WB P.66 https://www.youtube.com/watch?v=83-_GObxk_k
