## Learning Outcomes for Static Electricity

The list below displays sample learning objectives for the unit on Static Electricity. The various activities from the Lesson Plans have been organized by objective. This format of organizing The Physics Classroom's activities may be more useful to some teachers than the Lesson Plan format. It is worth noting that the activities identified below only include those activities included on the Lesson Plans and in the Pre-Built Task Tracker courses. Additional activities are referenced on the Teacher Notes page.

### 1. Charged vs. Uncharged Objects

Use an understanding of the structure of an atom to describe the distinction between neutral, positively-, and negatively-charged objects; in terms of subatomic particles, explain how a neutral object can become charged and how a charged object can become neutral.

### 2. Charge Interactions

Identify all the interactions between the two types of charged objects and neutral objects; use such an understanding to make a claim regarding the type of charge on an object if given observations of how it interacts with objects of known charge.

### 7. Coulomb's Law

Use the relationship between the electric force, the distance between the charged objects, and the quantity of charge on the objects in order to calculate the force or to predict the effect of changes in Q and d on the force.

A subscription allows teachers to set up classes, add students, customize online assignments, view student progress/scores, and export student scores. Task Tracker accounts allow your students to begin assignments in class or at school and to finish them at home. View our Seat and Cost Calculator for pricing details.

2. The Solutions Guide
We publish a free curriculum with >200 ready-to-use Think Sheets for developing physics concepts. The Solutions Guide is a download containing the source documents, PDFs of source documents, and answers/solutions in MS Word and PDF format. An expanded license agreement is included with the purchase. (Cost: \$25 download)

3. Teacher Presentation Pack
This is a large collection of downloadable content packed with nearly 190 Microsoft PowerPoint slide decks, the corresponding Lesson Notes (as PDF and fully-modifiable MS Word format), about 170 animations (in .gif, .png, and .mp4 file formats), a countless number of ready-to-use images (including the original source documents that would allow for easy modification of those images), and a license that allows teachers to modify and use all the content with their classes on password-protected sites (such as course management systems).  (Cost: \$40 download)

4. Question Bank
We distribute a Question Bank that includes more than 9300 questions neatly organized according to topic. The Question Bank is the perfect tool for busy teachers or new teachers. Even if you don't use the website with your classes, the Question Bank will assist you in quickly putting together quizzes, tests and other documents with high-quality questions that target student's conceptions of physics principles. And if you do use The Physics Classroom website, the Question Bank is the perfect complement to the materials found at the website. (Cost: \$25 download)
