Static Electricity Objectives To know the 3 parts of an atom and their charges To understand how objects can become electrically charged.

Electric Charge Read pg. 633-636. Take notes in Comp. Book on: Why do atoms have an electric charge? What causes objects to gain a static charge? What determines whether an object gains a + or – charge?

Intro to Atoms Atoms are the building block of all matter Even small objects have millions of atoms Atoms are made of 3 different particles

Atoms have charged particles Protons have a positive charge.

Atoms have charged particles Electrons have a negative charge.

All Matter has an electric charge Unlike (opposite) charges attract.

All Matter has an electric charge Like charges repel.

Materials can become electrically charged. At first, a balloon and a glass tube each have balanced, neutral charges.

Materials can become electrically charged. When they are rubbed together, electrons move from the glass tube to the balloon.

Materials can become electrically charged. Afterwards, the balloon has a negative charge and the glass tube has a positive charge. Friction caused the movement of electrons Static charges are caused by the movement of electrons, resulting in an imbalance of positive and negative charges.

Output page ISN 44 Answer questions 1-6 from page 640 in your textbook IQIA. Read “Electric Eels” on page 641. Answer questions 1 & 2 IQIA. Draw a picture of the eel. Show the positive and negative charges in your drawing.

Electric Charge and Static Electricity STATIC ELECTRICITY is the buildup of electric charges on an object.

Friday, October 14th Entry Task Write down three ways you used electricity today. Schedule: 19.1 Static electricity activities Objective: I will explain how charged particles behave. Please Have on Desk: ISN open to 19.1 notes, entry task brochure Homework Complete activity Read pages 642-649

Static Electricity Objectives To describe, in pictures and words, how objects can be come electrically charged. To discover what happens to the built up electrical charge in objects.

Station 1 Rub the metal rod with the plastic bag, then try to pick up the styrofoam pieces. Are you able to pick up pieces of styrofoam? Have you created an opposite charge? Explain how you know.

Station 2 Rub both balloons on counter Hold each balloon by the string and bring them close to each other. What happens? Why does it happen? Draw a picture of the charges on each balloon.

Station 3 Rub the plastic rod with the plastic bag Put the plastic rod close to the styrofoam pieces in the pie tin. Make an observation about what occurs. Are the rod and styrofoam opposite charges? Explain how you know.

Station 4 Create friction between the ruler and any other object (book, table, jeans etc…) Put the ruler close to the Cheerio. What occurs and why? Draw a color picture of the ruler and any other object after you rubbed them together. Show the charges.

Station 5 Rub the comb on the fabric. Try to pick up the paper pieces. Explain what occurs.

Station 6 Rub the ruler with the plastic bag, then put the ruler near the soda can. What happens to the soda can? Draw a picture of the charges on the ruler and the charges on the can.

Finally, Return to your seat and work on the Charging by Friction worksheet

Electric Charge and Static Electricity There are 3 common ways for an object to become charged: Friction Conduction Induction The charge on an object can be detected by an electroscope.

Electric Charge and Static Electricity Friction: Rubbing two objects together can cause electrons to be “wiped” from one object and transferred to the other. Ex: If you rub a plastic ruler with a cloth – electrons are transferred from the ruler. The ruler becomes negatively charged and the cloth becomes positively charged!

Electric Charge and Static Electricity Conduction: Charging by conduction occurs when electrons are transferred from one object to another by direct contact.

Electric Charge and Static Electricity Induction: Charging by induction occurs when charges in an uncharged object are rearranged without direct contact with a charged object. Ex: A negatively charged balloon induces a positive charge on a small section of wall because the electrons in the wall move away from the balloon.

Exit Ticket When you create __________ between your hair and a balloon, _________are transferred from the hair to the balloon. This makes the 2 objects ___________ charges The balloon and the hair are ___________ to each other. THIS IS _______ ________
