QUIZ on the electroscope lab and charging Today!
Today, we'll be starting an investigation into electric force. As a whole class, we'll be doing two labs, but each lab group will collect data for only one of the two labs. Then the groups will share the data with a partner group. The groups will either do:
↩️ Pivot Interactives lab called "Forces and Electric Charge I: Force vs Distance (Scaffolded)" In this activity, we'll try to quantify the relationship between the electrostatic force and the distance between two charged objects. This lab will focus on our new concept of electrostatic force, but will utilize lab skills that we've used in previous labs such as how to linearize graphs to find mathematical relationships as well as how to use slopes and intercepts to quantify the relationship.
↩️ Pivot Interactives lab called "Forces and Electric Charge II: Force vs Charge (Scaffolded)." In this activity, we'll try to quantify the relationship between the electrostatic force and the charge on two objects. This lab will also focus on the same skills as the previous lab. Then, the focus will be consolidating the results from both labs to come up with a relationship between electrostatic force, distance, and charge. While focusing on our new concept of electrostatic force, and utilizing the same scientific skills in the last lab, this lab also focuses on the skill of combining two experiments to find the mathematical relationship between three variables.
If your group finishes early, then you will exchange data during this period.
Each person will be responsible for analyzing their own data for both labs. The labs will be graded individually. Getting data for your group's assigned lab is due at the beginning of next class so that we can share data at that point. Then, the completed analysis is due in ↩️ Pivot by the date below.
Homework: ↩️ Pivot labs are due on Tuesday, March 11th at 10pm. No late work will be accepted in ↩️ Pivot. Before next class, completely finish the lab that your group was assigned so that you don't have too much work to finish the other lab. Do the intro to the lab you were not assigned as well.

Today, we'll make sure to exchange data so that you have data for both labs. Each person will be responsible for analyzing their own data for both labs. The labs will be graded individually. The completed analysis is due in ↩️ Pivot by the date below.
We'll also do test and quiz corrections today as well as finishing ➕ Positive Physics if you have not completed it yet.
Homework: ↩️ Pivot labs are due on Tuesday, March 11th at 10pm. No late work will be accepted in ↩️ Pivot.

Today, we'll put together what you were supposed to learn in the Pivot labs. We will review how to use Coulomb’s Law by going through the first five slides of the Coulomb's Law Presentation. We will draw similarities and differences to Newton’s law of universal gravitation (inverse square law). Note that the unit for charge we'll be using in Coulomb's Law is the Coulomb (abbreviated C). The magnitude of charge on an electron or proton is e = 1.60 x 10-19 C.
Then, complete the 📄 Coulomb's Law WS.
Finally, we'll practice Coulomb's Law problems by doing 📖 Coulomb's Law textbook problems #10, 11, 13, 14, 19, 66.
Presentation: Coulomb's Law Presentation (focus on the first 6 slides)
Handout: 📄 Coulomb's Law WS
Homework: Finish the problems above. If you missed today's class or are looking for additional support, you can catch up on Coulomb's Law by watching this video:
