This year's edition of Rings of Fire!

Students are given initial height and velocity of the launched marble. Each group has to calculate the height of their ring at their assigned horizontal distance.

I know AI is everywhere in our lives, but this one really surprised me. I'm uploading my recommendation letters, and Naviance has offered to write my rec letters for me, using just 4 bits of information from me.

The absolute gall to call this "meaningful and personalized"

#EduSky #iTeachPhysics
Screenshot from Naviance: "Get started with your recommendation for [redacted]. To generate a meaningful and personalized recommendation letter, select the information you'd like to highlight. You can also set the tone, level of formality, and your relationship to the student. After you make your suggestions, generate the letter. How formal should this letter be? What tone would you like to set? What's your relationship to the student? Would you like to use bullet points? Upload a template letter.

Update: It appears that this question was in fact not thrown out? No scoring commentary yet, but 2 points for a dimensional analysis question in which the dimensions don’t make sense 😑🎢

Link to scoring guideline: apcentral.collegeboard.org/media/pdf/ap...
Picture of text: AP® Environmental Science 2025 Scoring Guidelines G Calculate the energy use in the school building in kilowatts per year using LED light bulbs. Show your work. Point 09 One point for the correct setup to calculate the energy use in the school building in kWh/year using LED light bulbs. Examples of acceptable responses may include the following: • (2.8 × 10* bulbs) x 0.0085 kilowatt x 2,340 hours • (2.8 × 10^4) × 0.0085 × 2,340 One point for the correct calculation of the energy use in the school building in kWh/year using LED light bulbs. Point 10 Examples of acceptable responses may include the following (if units are included in the response, kWh/year or kW/year are accepted): • 556,920 5.6 × 10^5 5.6E5

Thought maybe nobody had made a springs in series and parallel #iTeachPhysics simulation yet, but JavaLab has one here: javalab.org/en/springs_en/
physics simulation of 3 sets of springs, each holding up the same amount of mass. The first is 3 springs in parallel, the second is a single spring, the third is 3 springs in series.

First time teaching this class, and I don't think I came up with this idea (some fuzzy twitter #iTeachPhysics memory), but planning to have them guess the power rule first.
Worksheet titled "Magical Mystery Machine" At the top it reads: Shhhhh…don’t tell your math teacher that I know about this secret information… Mr. Freeman has discovered a magical mystery machine hidden in an old closet near the math department offices. It seems to take functions & turn them into other functions. What seems to be the rule for this operation? What are the missing functions? Below there are 3 columns, with functions in each cell. The titles are : Input Function, 1st Time Through, and 2nd Time Through. Between the columns are Mario Brothers question mark boxes with arrows pointing in and out, indicating the function goes through the box to become the function in the center, then again through the box to become the function on the end.

Starting to question my own sanity making Google Slides...in what way would this have made more sense?
Screenshot from a google slide reading "on the simulation linked in Google Classroom" where "linked in" is underlined in red, with a suggestion to change it to "linkedin" like the social media platform.

Another Reddit find: jello cube!

Seems like it would be fairly straightforward to show the lattice points and internal springs, and add some energy bars for #iTeachPhysics

Love this #iTeachPhysics toy my daughter got. Might need to get a class set to do an angular momentum lab.

From comics community on Reddit A black and white hand drawn comic with 5 panels 1: Isaac Newton saying, “If I have seen further, it is because…” 2: …a giant stood on my shoulder (a red X is shown with the drawing) 3: …I gave a giant a shoulder on which to cry (a red X is shown with the drawing) 4: …I was a giant (a red X is shown with the drawing) 5: …I stood on the shoulders of giants. Isaac Newton appears small standing on some giant arms (A check mark is shown.)
