Tried this for myself today. Decided to assign points based on which tape their marbles crossed: Red is +5, yellow is +3, and blue is +1. Falls off the table without crossing a tape, -1 😂

Definitely doing this again!

Does anyone have experience teaching APC E&M over a year? I’m assuming most of us teach it in 1 semester, but I’m curious if any schools are offering it as a year long course.

[Mario Carrillo @carrillophysics]

@BonkPhysics Not even close. I do 3 weeks of 1D and then about another 3 of 2D. The suggested time definitely doesn’t feel appropriate considering how strong of a foundation we need to build during those lessons on motion!

@MrJoeMilliano @kilroi22 I recently discovered that a B field is an E field from a moving charges frame of reference due to special relativity and now I can’t wait to teach E&M again next spring!

[Mario Carrillo @carrillophysics]

Do it already

Let’s give public school teachers a raise.

I’m pretty sure I’ve seen someone post a resistivity lab involving conductive clay…
Anyone in the #iteachphysics community know what I’m talking about? 😇

[Mario Carrillo @carrillophysics]

Just read the blog post, I can’t wait to try this with AP1!!

[Joe Milliano @MrJoeMilliano]

I love watching students faces light up as they do electrostatics experiments. They may be the closest thing we have in the real world to magic. #iteachphysics

[Mario Carrillo @carrillophysics]

@BonkPhysics Thanks for the heads up!

[Mario Carrillo @carrillophysics]

Teaching APC E&M for the first time starting tomorrow…
Wish me luck 😅

When the normal force is "turned off", there is no friction!

@cossettej This is amazing! Where did you get the platform?

[Mario Carrillo @carrillophysics]

@DarekDewey This is genius! If I have one of these in my storage room we’ll definitely try it out

[Mario Carrillo @carrillophysics]

I’m trying to do the classic coffee filter lab with physics C to determine the drag coefficient of coffee filters but don’t have access to motion sensors…

Does anyone have any suggestions?

I’m thinking they can find v average for several tiny intervals?

@MrJoeMilliano @gnuphysics Awesome, I’ll check it out. Thank you!!

[Mario Carrillo @carrillophysics]

@Tweetlahuac I forgot this exists, thank you for the reminder!

[Mario Carrillo @carrillophysics]

@msruggerio Are you able to graphically check whether bv or bv^2 is the best model for a coffee filter using this method?

[Joe Milliano @MrJoeMilliano]

Uniform Circular Motion lab apparatuses are a go! Shoutout to @fpoodry for helping me troubleshoot the upgrade to @VernierST GoDirect Force Probes and Photogates #iteachphysics

[Mario Carrillo @carrillophysics]

Also, thank you @BarnettDreyfuss for sharing your materials again! I found these targets in one of your folders and I’ve been using them for so many activities!

[Mario Carrillo @carrillophysics]

APC had to determine the muzzle speed of their projectile cannon and decide how to verify their results. Once they were ready, i assigned each team a launch angle so that they could predict where the marble would land.

Also, they could not use a stop watch to determine v :)

PEMDAS is trending again so I'm begging you to just use clearer notation
