🟢 6: F 4/1, 🔵 8: F 4/1 - ↩️ Pivot electric force vs. distance

Today, we'll do a lab in ↩️ Pivot Interactives 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.

This lab is not due till Wednesday, April 6th at 10pm, but there will be another related Pivot lab due on the same day - a lab where we will explore the relationship between electrostatic force and charge. For these two labs, you will fill out another Collaborative Team Member Rubric in ✏️ Google Classroom, so think about how you might improve on your last self-assessment.

Homework: QUIZ Thursday, April 7th on the electroscope lab and charging.

🟩 6: T 4/5, 🟦 8: M 4/4 - ↩️ Pivot electric force vs. charge

Today, we'll continue the lab in ↩️ Pivot Interactives called "Forces and Electric Charge I: Force vs Distance (Scaffolded) ." 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.

Then, we'll start a lab in ↩️ Pivot Interactives 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.

Homework: QUIZ Thursday, April 7th on the electroscope lab and charging. Both "Forces and Electric Charge" ↩️ Pivot labs are due on Wednesday, April 6th at 10pm. Don't forget about the Collaborative Team Member Self-Evaluation in ✏️ Google Classroom also due Wednesday, April 6th at 10pm.

💚 6: W 4/6, 💙 8: T 4/5 - ➕ Positive Physics Coulomb's Law

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.

Next, watch the short video called "Pith Ball and Plastic Rod Attraction and Repulsion" (Lrn Fzx). In this video, you'll be able to observe electrostatic attraction and repulsion and hopefully get an idea of what a pith ball is.

Finally, we'll practice momentum problems in two dimensions by doing ➕ Positive Physics unit 22: Electric Charges & Force "work" problems from the sections:

  • electric force problems 1 (4 problems)

  • electric force problems 2 (due later, but try them if you want)

Presentation: Coulomb's Law Presentation

Handout: Coulomb's Law WS

Homework: QUIZ Thursday, April 7th on the electroscope lab and charging. Finish these ➕ Positive Physics problems by Thursday, April 7th at 10pm. Only completion score counts. No late work will be accepted. Also, don't forget that both "Forces and Electric Charge" ↩️ Pivot labs are due on Wednesday, April 6th at 10pm. Don't forget about the Collaborative Team Member Self-Evaluation in ✏️ Google Classroom also due Wednesday, April 6th at 10pm.
