Has anyone done the resistivity rod lab from Vernier? Its taken me a few years of grants to get the current meters, instrument amplifiers and resistivity rod sets. When I try to follow the lab manual the test seems to contradict the images? I'm hoping to use it for the first time next week. 🎢🧪

Van De Graff tune up 🧪🎢

Lots of props in electrostatics: Fairy lights that can light inwards to represent a negative charge or outwards for a positive charge. Hula hoop from the ceiling representing a ring of charge. I used chicken wire to make an odd Gaussian surface and a plastic sheet for an "infinite" nonconductor.🎢🧪

Got my @ncnaapt.bsky.social postcard for our Spring meeting! Looking forward to seeing everyone and meeting our keynote, astronaut Yvonne Cagle! 🎢🧪

While picking up soup & chili cans for rotational derby I was asked how one flavor tasted by another customer. I told him I wasn't going to eat it and that they were going to be rolled down an incline for science. I got a funny look but told him a bit more. Physics outreach can happen anywhere. 🧪🎢

Check out the many great workshops happening at #AAPTWM26 on Saturday, January 17th! These workshops are a perfect opportunity to gather with your colleagues and learn new #teaching techniques. ow.ly/UwMN50XmFlz #AAPTWorkshops #ITeachPhysics

Who in #iteachphysics had the list of physics events created by AI recently? I forgot to save it.😭 🎢🧪

Congratulations to the 2025 #PhysTEC National Teacher of the Year, Deborah Armstrong! Deborah teaches at Mineola High School. Each year, one national winner and several local winners are recognized for their exemplary work as high school physics teachers. ow.ly/qPEh50Xx1mP #ITeachPhysics

I write a lot of letters of rec for students that were juniors in my AP Physics class. So far, 28 students with 35 letters submitted, 6 to go by 11/1, 4 at a later date. There will be just as many current juniors asking for summer program letters. Necessary but exhausting process full of privilege.

Join us for the next AAPT Virtual Coffee Hour on "An Evening with Paul Hewitt" with presenters Paul Hewitt and John Suchocki, Conceptual Academy on November 18 at 7:30 pm EST. This event is open to the public. ow.ly/fJfn50XbSZy #AAPTCoffeeHour #PhysicsEducation #ITeachPhysics

🧪🎢Each year I do a pumpkin bungee drop in AP C Mech. Groups are randomly given a spring length? Spring constant, Pumpkin height and mass. They have to determine if it smashes or not and find either max speed if it survives or impact speed. I want to add graph sketching this year. Ideas so far: 1/2

Targeted advertising showed me an ad for a Chemistry Advent Calendar with cute ornaments each day. I am disappointed but not surprised there wasn't a Physics one. What would you put in such a countdown type calendar for Physics? I'm thinking small toy car, flying pig, tennis ball, rocket, etc.🎢🧪

#Teach180 blog post about how questions can grow into activities that can keep growing & getting better. This activity on positive/negative work started as a warm-up question but is now a nearly full day activity I added to again for next year. 🎢🧪 breebarnettdreyfuss.blogspot.com/2025/10/grow...

#Teach180 blog post explaining my day 1 Newton's Laws explorations, except we don't call it that yet. ✅️tennis balls ✅️bowling balls ✅️rubber mallet 🎢🧪 breebarnettdreyfuss.blogspot.com/2025/10/intr...

Vital piece of physics equipment for AP Physics to learn about forms on an object in UCM on a banked turn. 🎢🧪

Excited to see my @ncnaapt.bsky.social friends in about a month! 🧪🎢

Fabulous discussion of friction, just shared with my AP C kids and hope they have time to watch it before they start their forces test today! 🧪🎢

Forgot to share the Bear Bosun Chair I made last week. I had rushed something last year and always meant to redo it. When AP C students did the '86 FRQ about it, I made this. Simple wood frame as the bear "seat," rubber bands to hold it, eye hooks and wire at the top, binder clip at hands. 🧪🎢

@fnoschese.bsky.social do you know how to show students if their @desmos.com card sorts match the key? I feel like I've seen that on a card sort before but don't know how.

Days 15 and 16 of #teach180: It's OK to have boring days, and we can learn a lot on those days. lerner180.posthaven.com/days-15-and-... #iteachphysics

#teach180 blog post about the "salami problem" I do in AP C about equilibrium & forces. It's built up as a big memorable demo. I have done this same type of problem, based on a Hewitt Drew-it, in our college prep Physics as well, sans salami. 🎢🧪 breebarnettdreyfuss.blogspot.com/2025/09/sala...

#Teach180 blog post about the brick, balloon and block student experiment I do to illustrate changes in contact forces. Its based on Darek Dewey's set-up: breebarnettdreyfuss.blogspot.com/2025/09/bloc...

I want students to collect data of accelerating motion (not just constant/ave v). I want them to use equations to calculate other values and model the motion with graphs. I'm thinking driving because walking/running won't give final v. No tracking motion software. Anyone done a project like this?🧪🎢

Did NOT need an unscheduled evacuation with no information as to WHY, TODAY. 😤

#Teach180 blog (3rd post) about how I did name cards this year. It's the little things you try that help a classroom run smoothly. You have to try new things, tweak and try again if it doesn't. Each room and each year is different. breebarnettdreyfuss.blogspot.com/2025/08/name...

@lernerphysics.bsky.social reminded me how great daily reflection can be for teaching when he facilitated the Q&A after my award. I hope to move to a blog format but #Teach180 posts here will do for a start! 🧪🎢
