Electricity Bingo Bingo Review Get out a blank sheet of paper and fold it into 16 equal squares (4 x 4) Write down one vocabulary word in each box from the following list in a random order. Be sure to save space to write definitions in each box along with the word. Vocabulary Words 1. Charge 9. 2. Rule of Charged Particles 10. 4. Electric Field Static Electricity 5. Methods of Charging 3. 6. 7. 8. Conductor Insulator Voltage 11. 12. 13. 14. 15. 16. Current Resistance Circuit Ohm’s Law DC AC Series Circuit Parallel Circuit charge Protons and electrons Come near eachother they create 2 different forces Attraction repulsion charge • Protons and electrons • Come near eachother they create 2 different forces • Attraction • repulsion Electric field • Extends outward from anything with a charge • When charged particle moves into electric field, it is either pushed or pulled Atom review • Why are you not attracted to your pen or coat, etc • Remember atom is neutral because protons = electrons So how produce charge • Electrons are free to move • Lose electron = + charge • Gain electron = - charge • Just as atom can become charged, so can entire object Bingo Clue: A flow of electric charge (moving electricity) Bingo Clue: - Opposite charges attract - Like charges repel Bingo Clue: Opposition to the flow of electric charge Bingo Clue: Material with atoms containing loosely bound electrons which permits electrons to flow freely ex. copper (metal) Bingo Clue: Area around charged particles that exerts a force (push or pull) on other charged particles. Bingo Clue: When electrons always flow in the same direction EX. Battery Bingo Clue: Buildup of electric charges on an object. (unbalanced charge) Bingo Clue: Electrical Potential: amount of stored electric charge Note: it requires work to move a charge. Bingo Clue: A complete closed pathway for electricity to flow Bingo Clue: Current = voltage resistance I = V/R Bingo Clue: When electrons flow back and forth, reversing their direction regularly (+ to -) (- to +) EX. Wall Socket/Plug Bingo Clue: 1. Friction- rubbing two objects together 2. Conduction- direct contact of two objects 3. Induction- rearrangement of electric charge without touching Bingo Clue: When all parts of a circuit are connected one after another in the same path Bingo Clue: Physical Property of Matter that can give rise to an electric force of attraction or repulsion • Protons (+) • Electrons (-) • Neutrons (no charge) Bingo Clue: Material with atoms containing tightly bound electrons that do not permit electrons to flow freely ex. rubber Bingo Clue: IF YOU JUST SAID BINGO… YOU OWE RYAN A POP! Bingo Clue: When the parts of a circuit are connected in separate pathways or branches Chemistry Review Notes The following note pages are the definitions from your bingo card that need to be formally recorded in your science journal. The Basics Charge: Physical Property of Matter that can give rise to an electric force of attraction or repulsion Protons (+) Electrons (-) Neutrons (no charge) Rule of Charged Particles: Opposite charges attract, Like charges repel Electric Field: Area around charged particles that exerts a force (push or pull) on other charged particles. Static Electricity: Buildup of electric charges on an object, (unbalanced charge) Methods of Providing Charge 1. Friction- rubbing two objects together 2. Conduction- direct contact of two objects 3. Induction- rearrangement of electric charge without touching Electricity Terms Conductor: Material with atoms containing loosely bound electrons which permits electrons to flow freely (EX. Copper, metals) Insulator: Material with atoms containing tightly bound electrons that do not permit electrons to flow freely (EX. Rubber) Voltage: Electrical Potential: amount of stored electric charge Note: it requires work to move a charge. Current: A flow of electric charge (moving electricity) Resistance: Opposition to the flow of electric charge Ohm’s Law A relationship exists between current, voltage, and resistance. Current = Voltage Resistance I=V R AC vs. DC Alternating Current (AC): When electrons flow back and forth, reversing their direction regularly (+ to -) (- to +) EX. Wall Socket/Plug Direct Current (DC): When electrons always flow in the same direction EX. Battery Circuits: Series/Parallel Circuit: A complete closed pathway for electricity to flow Series Circuit: When all parts of a circuit are connected one after another in the same path Parallel Circuit: When the parts of a circuit are connected in separate pathways or branches
