Pd 8 - QUIZ Today on the electroscope lab and charging.
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.
Homework: Both "Forces and Electric Charge" ↩️ Pivot labs as well as Collaborative Team Member Self-Evaluation in ✏️ Google Classroom are all due on Wednesday 10pm. We'll work on finishing both labs next class as well.
Pd 6 - QUIZ Today on the electroscope lab and charging.
Today, we'll finish both labs in ↩️ Pivot Interactives called "Forces and Electric Charge I: Force vs Distance (Scaffolded)" and "Forces and Electric Charge II: Force vs Charge (Scaffolded)." The focus today 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: Both "Forces and Electric Charge" ↩️ Pivot labs are due on Wednesday 10pm. Don't forget about the Collaborative Team Member Self-Evaluation in ✏️ Google Classroom also due Wednesday at 10pm.
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 (PH)" in ✅ GoFormative.
Then, 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 19: electric force "work" problems from the section:
electric force (5 problems)
Homework: Finish these ➕ Positive Physics problems by Thursday, April 29th at 10pm. Only completion score counts. No late work will be accepted. Also, "Coulomb's Law WS (PH)" in ✅ GoFormative is due on Friday, April 30th at 10pm. If you missed today's class or are looking for additional support, you can catch up on Coulomb's Law by watching this video:
