AT Cycle 28

🔴 1: F 2/26, 🟡 3: F 2/26a JJ Thomson's experiment (1)

Today, as our daily quiz, we'll do some practice with a mass spectrometer. Upload your screenshot to ✏️ Google Classroom by Sunday at 10pm.

Then, we'll use a simulation of a cathode ray tube to repeat the 1897 experiment by J.J. Thomson to find the charge-to-mass ratio. (It's actually not exactly the same, but there are similar elements.) Find the experiment in ↩️ Pivot Interactives called "JJ Thomson Experiment - finding charge-to-mass ratio." In this lab, you will combine your knowledge of electrostatics, magnetism, and circular motion. This lab is due in Pivot on Tuesday, March 2nd Friday, March 5th at 10pm.

🟥 1: M 3/1, 🟨 3: F 2/26b JJ Thomson's experiment (2)

Today, we'll continue our work on JJ Thomson's experiment from the previous post.

With any time remaining, finish the problems from this magnetism unit, find additional AP problems on magnetism, or continue your review of all of the induction topics you should have learned last year on my AT Induction Review page.

Homework: Complete the mass spectrometer activity in ✏️ Google Classroom by Sunday 2/28 at 10pm, and complete the charge-to-mass ratio lab in Pivot by Tuesday, March 2nd Friday, March 5th at 10pm. Quiz on Biot-Savart next class Tuesday, March 2nd!

❤️❗ 1: T 3/2a, 💛❗ 3: T 3/2 induction review (1)

Quiz on Biot-Savart Problems TODAY!

If you have not yet completed JJ Thomson's experiment, please make sure you have a good handle on that. This lab is due tonight at 10pm.

In groups today, we'll try to compile a list of facts and equations that you should know about induction. We'll collect all of the ideas and make sure you understand the following:

• Lenz's Law (to find direction of induced current)

• Faraday's Law of Induction (to find magnitude and direction of induced current)

• Motional e.m.f. (moving bar through magnetic field)

• Transformers (ideal transformer equation)

• how motors work

• how generators work

Take notes on all of above and upload pictures of your notes to ✏️ Google Classroom assignment due Thursday at 10pm.

Homework: Make sure you have reviewed all of the induction topics you should have learned last year on my AT Induction Review page.

📕 1: T 3/2b, 📒 3: W* 3/3 induction review (2)

Today, we'll continue with the previous post. Upload pictures of your notes to ✏️ Google Classroom assignment due Thursday at 10pm.

With any time remaining, continue on to the next post.

Homework: Make sure you have reviewed all of the induction topics you should have learned last year on my AT Induction Review page.
