You can find the file for the arrows at @brianwfrank's blog post: teachbrianteach.com/2018/08/19/mag… But I modified his file. Removed color fill inside shapes and photocopied into colored paper instead. Added double-headed arrows to acceleration vectors. Will post modified file later.
Day 36: Modified the traditional "up and down the ramp lab" to use cards! Students tried matching position and velocity graphs to the 8 verbal description cards. Then they tested their predictions with motion detectors and fixed any incorrect predictions. #teach180 #iteachphysics
Cards made this lab so much better! Instead of having students just draw their predictions, the cards allowed for richer discussion between students. And instead of having students draw what they see on the LabQuest (which usually has blips), they find the closest matching card.
Here's the file with the cards: 1drv.ms/w/s!ApnZRKSJ0l…

Day 80: Which team will win the tug-of-war? Students take data to calculate the coefficient of friction between their shoes and the floor in order to find out. #teach180 #iteachphysics
Day 81: Every free moment I had today was spent piloting a new rotation lab:
• collecting data to see how clean/repeatable it is
• analyzing data to see if it works as predicted
• figuring out how to account for friction and minimize air resistance
#teach180 #iteachphysics
• Clean and repeatable data? Yes.
• Did data analysis work as predicted? Not initially b/c I made a physics error that I didn't realize until after school. This frustrated me all day. I almost gave up, thinking there was just too much friction/air resistance to work.
• After fixing my error, data analysis was great and I got under 3% error.
• Minimized air resistance by adding a wooden dowel into the horizontal tube.
• Accounted for friction by graphing torque vs. angular acceleration, so slope = inertia and y-int = frictional torque.
My initial physics analysis error that took me all day to figure out? I mistakenly used the angular acceleration of the pulley (rotational motion sensor) as the angular acceleration of the T-shaped apparatus. #oops
Day 82: Students had time to review and prep for their 2nd quarter lab practical. Here's the 3 tasks students must complete individually. #teach180 #iteachphysics
Day 83: Lab to determine the internal resistance and emf of a 6 volt battery. #teach180 #iteachphysics

Day 85: Which way will it roll? Students whiteboarded predictions then tested with yo-yos. Followed up with Hewitt's worksheet, testing each case and determining the torque. Ended with task to determine the angle needed for yo-yo to slide w/o rolling. #teach180 #iteachphysics
BTW, Dollar Tree has the "butterfly" style yo-yos for $1 each, called the Soaring Eagle. They are perfect because they don't tip over easily while rolling.
Day 86: A sequence of photos to introduce rolling motion. (Photos not mine.) #teach180 #iteachphysics

More information about Invention Tasks, including other examples, can be found here: depts.washington.edu/pits/index.html #iteachphysics
Day 112: Happy International Women's Day! Thanks to @neverthelesspod for these great women in STEM posters we have on display in the science hallway! medium.com/nevertheless-p… #teach180 #iteachphysics #IWD2019
Day 113: Using conservation of momentum to determine if the same M&M cannon was used in 2 different videos. Thanks to @bohacekp for making the videos and to @treddtaylor for the idea to add mass and velocity columns in the momentum table. #teach180 #iteachphysics

Day 125: Introduction to Gauss's Law. I tried a new approach this year, which feels like it's been the best yet. This sequence of problems helps students intuit that ϕ = q/ε, no matter the shape: 1drv.ms/w/s!ApnZRKSJ0l… #teach180 #iteachphysics
It's important to note that my students were first introduced to the concept of flux back when we did Faraday's Law, so they didn't need much help figuring out how to calculate electric flux.
Day 126: Breaking the simple pendulum model! Students predict the theoretical periods for a 1-m pendulum bob and a 1-m stick. Then they find the periods experimentally and compare. Why are the predictions for the 1-m stick so far off? #teach180 #iteachphysics
Day 127: How does the period change as the mass is moved down the meter stick? What position gives the shortest period? (An S-hook clamped to a rod with a binder clip makes for a nice pivot.) #teach180 #iteachphysics
Day 128: Crumple Zone Testing and Modification. The goal is to not let the empty film canister topple forward. (Inspired by a similar activity in the Active Physics textbook.) #teach180 #iteachphysics
It's hard to see in the previous video, but there's a flap of tape on the front of the canister that allows it to tip over without sliding off.
Day 129: Getting quantitative with our crumple zone investigation by using force sensors and motion detectors. Comparing the force vs. time graphs for different cushioning materials. #teach180 #iteachphysics

Day 139: Starting a project-based unit on roller coasters, but instead of having everyone do every lab in the unit, we are trying the jigsaw method. First, each expert group does a different lab. Then, home groups pool their knowledge for the project. #teach180 #iteachphysics
For folks looking for more information about the project -- it is modeled after Chapter 4 of Active Physics. Here's a PDF with a detailed outline of all the chapters in the book: web.archive.org/web/2009090221… Great place to get ideas for physics projects! #iteachphysics
Also, the jigsaw graphic is not mine. It's from here: …iesforspecialinterventions.weebly.com/jigsaw1.html
Day 140: Students are using a class notebook in OneNote to record their lab results. That way, everyone in the class can see all the different experiments done by the other expert groups in the jigsaw. #teach180 #iteachphysics
Day 141: Used @desmos scientific calculator to breakdown problems that required many steps. Being able to see intermediate values along the way allowed us to catch and fix mistakes easily, without having to recalculate everything from the start! #teach180 #iteachphysics
Just noticed I forgot the negative sign in the exponent for G in the last step. #oops
Day 142: AP Mechanics students working on a great PhET lab about orbits written by @kilroi22. You can get the lab here: phet.colorado.edu/en/contributio… #teach180 #iteachphysics

Day 158: NGSS, NYSSLS, ADI, and 3D instruction. Got these books from our department leader at today's department meeting. Looking forward to digging in! #teach180 #iteachphysics
Day 159: Today was Wellness Day. No regular classes. Students attended workshops about a variety of topics. @MrLonghurst and I led a short session about the myth of meritocracy, based on lessons from underrep.com. (Thanks @RiPhysKin!) #teach180 #iteachphysics
These were the other workshops, plus there was a guest speaker on addiction. And at lunch there were tables set up with folks from outside organizations such as GLSEN. Such a shame that the majority of students decided NOT to come to school today.
Day 160: I made a HW guide to help students with this week's WebAssign problems. Although problems aren't solved completely, hopefully the explanations will be more helpful than Chegg or Yahoo Answers. And helpful to those who don't like asking for help. #teach180 #iteachphysics

More puzzles and clues hidden inside the locked pouches:
Here's a link to the file. I tried my best to explain how it works.

I bought 3 extra locks and 4 zipper pouches from Amazon to supplement the standard breakout kit.
Attaching clues to whiteboards was helpful and gave students a VNPS to show everyone their thinking and allowed for easier collaboration. Whiteboards were propped up on small easels:
Day 175: Proctoring final exams. #teach180 #iteachphysics
Day 176: Senior Internship Fair! Seniors sharing what they learned during their 5-week internships. Such a wide range of experiences: organic gardening, mobile phone repair, helping at the local library... #teach180
... More internships: architecture, state government energy initiative, painting murals, and PCB design.
Day 177: Working with colleagues to plan the beginning units for next year's college-prep physics course. Link to pendulum wave QFT video: #teach180 #iteachphysics
Day 178: More proctoring and planning for next year! Looking to incorporate more projects and engineering design activities. I like the Pasta Cantilever challenge for wrapping up our balanced forces unit: static.nsta.org/pdfs/BookBeat2… #teach180 #iteachphysics
Day 179: In order for students to build a wave pendulum next year, they will first need to collect data for the length and swing rate (not period) of various pendulums. However, the graph isn't linear. But a power law fit works well. #teach180 #iteachphysics
I'm thinking about only using 2 types of curve fits next year:
• y ~ mx+b for linear graphs
• y ~ ax^b+c for non linear graphs and looking at the value of b to determine if the relationship is quadratic, inverse, inverse square, square root, etc.
Day 180: For the past 2 years, I've been part of a wonderful cohort of innovative teachers from across my district. This portfolio documents the new methods I've tried: QFTs, performance assessments, and project-based learning: sway.office.com/nEpOWEU5AgDLAC… #teach180 #iteachphysics
Day 181: Graduation! Congratulations to the Class of 2019! 🎓👍🏻 #teach180
Day 182: Last day and final post. Goodbye school, hello summer! #teach180
