AT Cycle 21

🔴 2: W 1/17a, 🟡 4: T 1/17 - time-dependent RC circuits

Today, we'll learn what a capacitor does when it's in a circuit.  This PhET simulation will assist with our investigation.  We will compare and contrast a capacitor with a battery.  Then, we'll use Kirchhoff's Laws to determine an expression for the charge of a capacitor as time changes.  

Then, we will collaborate to understand Jon Ting's video by forming heterogeneous groups/pairs to ensure everyone understood the derivation.  NOTE: When Jon Ting talks about the "area under the curve," he made a mistake - it's not area under the curve.  Try to make sense of it without thinking about area.

Homework:  Read sections 27-3 & 27-4 in your textbook.  Rewatch Jon Ting's video.  

🟥 2: W 1/17b, 🟨 4: W 1/17 - capacitor pre-lab

Today, we'll practice the derivation of the charge on a capacitor over time (charging and discharging) as well as the currents over time.  Submit a picture of your work to ✏️ Google Classroom.  

Then, we'll complete Capacitor Pre-Lab in ✅ Formative.com utilizing what you learned from South alumnus Jon Ting's video on how to use Kirchhoff's Laws to determine an expression for the charge of a capacitor as time changes.

Homework:  Quiz on equivalent resistance (combo circuits) and Kirchhoff's Laws Friday, January 20th.  Submit a picture of your derivation of charging and discharging equations in ✏️ Google Classroom by tonight Wednesday at 10pm.  If you did not finish the pre-lab in  ✅ Formative.com above, do so by Wednesday at 10pm.  Watch the following videos on energy stored in capacitors.  They are similar with slightly different approaches.

❤️ 2: Th 1/19, 💛 4: F 1/20a - breadboard

Today, start a lab to learn about the circuits equipment we have available to us in order to measure the voltage and current "through" a capacitor.  In particular, you'll learn how to build an RC circuit with a 1F capacitor breadboard.  This is a warm up for your big formal lab next lab period, so make sure you understand this one!  

Presentation:  Breadboard Intro

Homework:  Quiz on equivalent resistance (combo circuits) and Kirchhoff's Laws Friday, January 20th.  Read sections 27-3 & 27-4 if you haven't already.  Rewatch Jon's video on charging and discharging capacitors if you feel like you need to.   

📕❗ 2: F 1/20, 📒❗ 4: F 1/20b - 1F capacitor lab (1)

Quiz on equivalent resistance (combo circuits) and Kirchhoff's Law TODAY!

Today, perform the lab to learn about the circuits equipment we have available to us in order to measure the voltage and current "through" a capacitor.  In particular, you'll learn how to build an RC circuit with a 1F capacitor breadboard.  This is a warm up for your big formal lab next lab period, so make sure you understand this one!  Today, you'll just start building your boards.  We won't take data today.

Homework:  Read sections 27-3 & 27-4 if you haven't already.  Rewatch Jon's video on charging and discharging capacitors if you feel like you need to.  QUIZ Thursday, January 26th on derivation of charging and discharging equations (marking period 2).  Watch the following videos on energy stored in capacitors if you have not already.  They are similar with slightly different approaches.
