Bell Ringer: Based on previous knowledge, what type of charge is an electron? Fact of the Day: Electric eels can produce strong electric shocks of around 500 volts for both self defense and hunting... Lesson-What is Electrostatics: PART 1- Pg. 10 Joke of The Day: Why did the tree go to the dentist? A: It had nothing to be positive about… Joke of The Day: Why was the electron so sad? Agenda 1. Bell Ringer What is Electrostatics PART 1: -Background on Atoms -Background on Atoms BM A.1-Explain knowledge by using specific terms using specific terms -Pith Ball Activity -Pith Ball Activity BM A.1-Explain knowledge by using specific terms using specific terms BM C.4-Validity of Method BM D.1-Explain how Science is Applied Applied BM D.3-Scientific Language - Foldable-The Atom and the Pith Ball - Foldable-The Atom and the Pith Ball BM A.1-Explain knowledge by using specific terms using specific terms 3.

Proton Neutron Electron If the positively charge nucleus balances the negative charge of the electrons the atom is balanced. ++ + + + ++ + + + - - - - - - - - - - At the end of the lesson I should be able to: explain what is electrostatics and how it relates to charge Lecture/ Notes: What is Electrostatics PART 1- 1 electron= -1 1 proton= +1 0 Statement of Inquiry: Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk. Factual Inquiry Question: What is an electron? Conceptual Inquiry Question: How are charges created? Debatable Inquiry Question: Can electrostatics have enough charge to harm someone?

If an atom is not balanced it can be persuaded to give up an electron from its outer shell. Electrons migrate to other objects all the time ProtonProton ProtonProton Electron Electron Electron Electron ProtonProton Proton Proton Proton Electron Electron Electron Electron Charge just transfers to the other object An atom that gets its electrons taken away is called an ion. Lecture/ Notes: What is Electrostatics PART 1- At the end of the lesson I should be able to: explain what is electrostatics and how it relates to charge Statement of Inquiry: Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk. Factual Inquiry Question: What is an electron? Conceptual Inquiry Question: How are charges created? Debatable Inquiry Question: Can electrostatics have enough charge to harm someone?

4 PITH BALL ACTIVITY ESSENTIAL QUESTION: How can I show the force between two objects by creating a charge between them? BACKGROUND: A pith ball is a very small, lightweight object that picks up electric charge quite well. A charged pith ball works well to show the force between two charged objects. Hypothesis: If ____________________________________________, _______________________________________________________ then ____________________________________________________. Lecture/ Notes: What is Electrostatics PART 1- At the end of the lesson I should be able to: explain what is electrostatics and how it relates to charge Statement of Inquiry: Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk. Factual Inquiry Question: What is an electron? Conceptual Inquiry Question: How are charges created? Debatable Inquiry Question: Can electrostatics have enough charge to harm someone? there is a charge between two objects there is a force (push or pull)

5 PITH BALL ACTIVITY DIRECTIONS: Step 1: Rub the glass rod is with the fur or silk. the silk rubs some electrons off the rod. The rod thus becomes positively charged. Step 2: Place the glass rod near the two pith balls. What happens? (Explain in your own words below and draw a picture to represent the reaction) Step 3: Now take the rubber rod and rub it with fur or silk. the rod rubs some electrons off the fur. The rod thus becomes negatively charged and attracts the positively- charged pith balls. Step 4: Place the rubber rod near the two pith balls. What happens? (Explain in your own words below and draw a picture to represent the reaction) Pic for Step 4 Pic for Step 2 Lecture/ Notes: What is Electrostatics PART 1- At the end of the lesson I should be able to: explain what is electrostatics and how it relates to charge Statement of Inquiry: Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk. Factual Inquiry Question: What is an electron? Conceptual Inquiry Question: How are charges created? Debatable Inquiry Question: Can electrostatics have enough charge to harm someone? The two pith balls attract each other ++-- The two pith balls repel each other -- --

6 FOLDABLE-THE ATOM AND THE PITHBALL Complete the following foldable by cutting out the boxes and cutting the dark solid lines. The foldable are in the back of your class workbook. Glue the gray part in your book and place the answers underneath the tabs. Lecture/ Notes: What is Electrostatics PART 1 At the end of the lesson I should be able to: explain what is electrostatics and how it relates to charge Statement of Inquiry: Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk. Factual Inquiry Question: What is an electron? Conceptual Inquiry Question: How are charges created? Debatable Inquiry Question: Can electrostatics have enough charge to harm someone?

Review of Lesson 1.What are the three part of an atom? ____________________ 2. Complete the following sentence based on the lesson: If the positively charge nucleus balances the negative charge of the electrons the atom is ____________________. 3.When static charge is present, and two objects are of opposite charges they: a. connect b. push away c. both d. none of the above 7 Lecture/ Notes: What is Electrostatics PART 1- At the end of the lesson I should be able to: explain what is electrostatics and how it relates to charge Statement of Inquiry: Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk. Factual Inquiry Question: What is an electron? Conceptual Inquiry Question: How are charges created? Debatable Inquiry Question: Can electrostatics have enough charge to harm someone? Complete the following the review of lesson for a formal assessment at a later time.
