How can we describe electrostatics? How can we charge objects?
F 3/27 (elearning) After making observations in the Electroscope Lab last class, you will try to construct a model of electrostatics to describe the operation. In your written model, you should describe what you know using the words on the Electrostatics Vocabulary List (bold, highlight, or underline these words as you use them in your document). Start this document in Google Classroom by writing about the terms with which you are already familiar. We'll be learning about other terms in the next couple of lessons. Your written model should start with "All matter is made of..." and then go from there. Today, you'll construct and refine your written models for how an electroscope works. Then, you will try to explain the different methods of charging objects by refining and expanding on the information from the videos previously posted. Include these general explanations in your written model. Please read the resource provided below and try to finalize your written model of matter (The Physics Classroom  Electrostatics  review lessons 1 & 2). Remember that this is supposed to be a general statement about how charges interact in matter, not a specific explanation of how the electroscope works, so talk in general terms. Please make sure to bold, highlight, or underline the vocabulary words from the list. As you are writing, please keep all aspects of academic integrity in mind. I will check your progress in writing this model within the next 24 hours. Please make sure to have included some information about what you've learned from the posted resource.

What are the charges doing in the electroscope?
W 3/25 (elearning) Today, based on the videos you watched last class, we will attempt to explain what is happening inside the electroscope during the Electrostatics Lab. Try to draw excess charge by drawing positive and negative signs in your Electrostatics Lab and annotate with new vocabulary. (Let's assume that plastic becomes negative and acetate becomes positive for uniformity.) For example, here's what I'd expect to see for number 1. If there are no positive and negative signs, that does not mean that there aren't any positive or negative charges in that location (of course you know there will be protons and electrons there), but rather it just means that there are an equal number of those positive and negative charges. Then look at the Electroscope Lab Answers and make corrections on your own paper in a different colored pen, and try to do some research to really understand the ones you got wrong. Take pictures of all of your work including corrections and upload to the assignment on Google Classroom. Ask your classmates on your group chat if you have any questions. If you can't get answers through collaboration, email me, and we can set up a whole class Google Meet for next class Wednesday. Check the resource below for more explanations.

How can you visualize the charging of objects?
M 3/23 (elearning) Today, you'll deepen your understanding of what the process of charging looks like. In this exercise, you will visualize and draw where excess positive and negative charges appear while charging an object. You'll complete Electrostatics Charging WS (PH). This worksheet will help you to understand what is happening in your Electrostatics Lab and will give you hints as to how you will complete the next assignment. Handout: Electrostatics Charging WS (PH) Homework: Try to understand the answers to the above worksheet posted on Google Classroom. 
How does an electroscope work?
Th 3/19 (elearning) Today, we will try to describe what is happening when we operate a gold leaf electroscope. Watch the following video and record your observations on the Electrostatics Lab handout. See the example below the video for #1 for how to record your observations. Upload pictures of your handdrawn observations handout to Google Classroom. Handouts: Electrostatics Lab Homework: Then, please watch the following videos. Make a good effort to understand these videos, as you will be using the information in the next assignment on Monday. Email me if you have questions. 
How can models be used to find out physics information?
T 3/17 (elearning) Today, you'll take your lab data and do your final analysis. You should have a graph with three data points. Plot the points on a piece of graph paper. Linearize the graph if necessary. How do you extract the coefficient of kinetic friction from the best fit line? You should not be finding the coefficient using particular data points and averaging! That is not the way we do science! Upload pictures of your progress to Google Classroom. Only handdrawn graphs and analyses will be accepted. Also, in a separate document within the assignment, answer the question to the reflection and also upload this document to TurnItIn.com. II. Reflect: Why did we do this lab?

What kind of model would be most useful for police to investigate car crashes?
6: W 3/11 & F 3/13, 8: Th 3/12 & F 3/13 Today, in your group, you'll be collaboratively creating what you think will be the best model that the police could use to investigate car crashes. Homework: Finish your group model which is due on Wednesday, March 18th. Open lab notebook lab quiz on Thursday, March 19th. 
How could police use physical models investigate car crashes?
6: T 3/10, 8: W 3/11 Today, having already created a mathematical model of the car crash, you will use a physical model to take data for the Forensic Physics Lab. Your goal today is to finish your own individual writeup by hand. Homework: Finish your individual writeup. Make sure you do this! It's IMPORTANT!!! 
How well do you understand momentum?
6: M 3/9, 8: M 3/9 Momentum Exam TODAY! Homework: You should be able to complete your individual mathematical model for the Forensic Physics Lab during class time. It should be completed by next class. 
How do police use physics to investigate car crashes?
6: Th 3/5, 8: F 3/6 Today, we'll design a lab where we'll use physics from several past units to investigate car crashes. Your goal today is to come up with the mathematical model that will help us find the coefficient of friction between two surfaces. You've done this two other ways before, and this time, you'll design a third method using limited resources. Handouts: Forensic Physics Lab Homework: Study for Unit Test on Momentum next class Monday, March 9th. Remember that you must have all of your work and your data written by hand INDIVIDUALLY! You should be able to complete your individual mathematical model during class time. It must be completed by the next class (day after test) on Tuesday, March 10th (pd 6) or Wednesday, March 11th (pd 8). 
Can you predict the outcome of an explosion?
6: W 3/4, 8: Th 3/5 Today, we'll perform a lab which will demonstrate the conservation of momentum in an explosion. The lab has two parts:
Homework: Study for Unit Test on Momentum  Monday, March 9th. Make sure you've completed all of the assigned problems. If you have any questions about this material, you must ask before the weekend.
