AP Physics 1: Video Summative
Students started the week by wrapping up angular motion graphs. I took a page from Andy Rundquist and Rhett Allain by doing video assessments. I posted a goal-less problem, and each student had to record a short video explaining their work. I really enjoyed watching the videos, especially because a lot of students talked about things that almost tripped them up, but a lot of students had technical issues submitting their work. For the next assessment, I may give students the option of doing a video or a purely written version.
Physics: Projectile Motion Problems
Students worked some problems representing projectile motion, then did a video summative assessment. I tried designating part of my office hours specifically for discussing the problems, and I had a few students take me up on it. It was very different from talking in person, but the students who came felt like they got a lot out of it. Since I’m doing office hours anyway, that will be a pretty easy routine to continue.
Chemistry Essentials: Formula Writing
Students worked on translating between chemical formulas, names, and particle diagrams. Students learned how to go between names and formulas in the first half of the course, but a lot of my students took the first half trimester 1 and haven’t had chemistry since November, so it was worth some review. Plus, the particle diagrams are new to all of my students. Going by their work and the students I’ve had a chance to talk to, a lot of them needed this week, but have now gotten the hang of these representations.
The biggest issue was helping students figure out how to submit their work through Schoology. Many of them rarely visited Schoology before we switched to distance learning, so this is a lot to take in. I decided that I need to hold the line on getting students to submit assignments on Schoology rather than emailing their work to me to keep myself from getting overwhelmed. Fortunately, our digital learning coach has been putting together videos and other resources I can send along and the para supporting the course is willing to walk students through submitting their work.
AP Physics 1: Assessment
Students took their quiz over angular momentum, and we have now officially finished content. Wooo! 2 class days to spare!
Physics: Reflection Lab
We got out the geo mirrors and some plane mirrors to start exploring reflection. I like to start each optics topic with a lab making qualitative observations. The instructions I gave students today need some work; students had trouble parsing the wording to make meaningful observations.
Chemistry Essentials: Backwards Problem
As a quick warm-up before taking the limiting reactants quiz, I had students whiteboard what I called a backwards problem. I gave them a reaction and told them what should be the limiting reactant, then had them sketch a particle diagram for a situation showing starting conditions that would lead to the right limiting reactant.
A few kids were feeling stressed out about this quiz, so we also took a few minutes to revisit the reassessment policy, including the fact that I’m putting retakes into our normal assessment process, which helped lower the stakes and let students feel a little calmer about the quiz.
AP Physics 1: Pivot Angular Acceleration
I am as part of Pivot Interactive’s Chemistry Fellows program.
Students used Pivot Interactives to find a relationship between unbalanced torque and angular momentum for several different bicycle wheels. I had them start by setting up a formula they could use to calculate the angular acceleration from the change in angular position and the time. My 2nd hour had a much easier time with this; I think the difference is they worked yesterday’s problems in small groups and quickly connected this task to some of the problems they’d done. My 4th hour had a sub yesterday who was a former physics teacher that decided to go through the problems as a lecture, so I think those students didn’t have as firm a grasp on the calculations.
Students took the Force Concept Inventory as a post-test. We normally give it before moving into simple harmonic motion, so they were a little rusty on thinking with forces, but I’m satisfied with the results.
Chemistry Essentials: Limiting Reactants
Students used nuts, bolts, and washers to start connecting mass to what I’d planned for them to see about limiting reactants yesterday. While both my sections were able to get through today’s activity without trouble, I need to figure out how to adjust for some issues yesterday. My 5th hour is co-taught, so my co-teacher ran the class and the majority of students easily finished yesterday’s activity and had the ideas I wanted them to have at this point. In my 6th hour, the sub decided to go over the answers to the accompanying worksheet as a lecture without projecting the simulation, which my students really struggled to follow. Several students helped themselves to a computer and worked through the activity as intended, and I’m having trouble getting mad at them for defying the sub. I think the activity with the simulation is worth doing, but between demand for the school computers and trying to keep both sections in the same place, I’m not sure how to give my 6th hour time in-class.
Today was our last day of regular classes before final exams.
AP Physics 1: Free Response
For my tri 2 final, I like to give most of a practice AP exam. Since our final periods are 90 minutes long, I had my students do the free response portion today. I took out the problems on circuits and rotation since my students haven’t seen those topics yet. Students seemed to feel pretty good afterward; I think they are internalizing that its okay not to nail the problems.
Physics: Mistakes Whiteboarding
We used some problems from the final review for mistakes whiteboarding. Students in this course have really bought in to the value of mistakes whiteboarding and I end up saying very little during these discussions. Its a lot of fun to listen to students during these discussions.
Chemistry Essentials: Mistakes Whiteboarding
We used some problems from the final review for mistakes whiteboarding. A lot of students were having some trouble focusing, which is not unusual for this course at the end of a tri; I think a lot of them are anticipating spring break and the start of the next trimester. My co-teacher and I made some changes to how we talked about particle diagrams this tri to emphasize them as a thinking tool, and it was a lot of fun to see some of that work pay off during the discussion today.
Tomorrow was originally scheduled to be a staff development day, so all three of my classes took assessments wrapping up their last topic.
AP Physics 1: Waves Assessment
This quiz included an experimental design problem off a past AP exam. My students still find those kinds of problems really intimidating, but I’m really pleased with the work on the quizzes I’ve looked at so far. In general, both this year and in the past, I’ve had a lot of trouble helping my students feel as confident as I think they should when it comes to the AP Physics 1 exam, and I think their reaction to experimental design problems is one symptom. I have noticed that one of my sections is much more confident, and I don’t think its coincidence that they are also a MUCH smaller section. As we get into the home stretch to May 7, I need to give some thought to how I can help all of my students recognize the progress I’ve seen in them.
Physics: Pendulum Assessment
Students took their quiz on pendulums, then started working on a final review.
Chemistry Essentials: Formula Writing Assessment
Students quizzed over formula writing. Most were feeling very good about their work at the end of the quiz, which is a great place to be at the end of the term.
Classes were a little shorter than usual today due to our winter week pep fest.
AP Physics 1: Quiz
Students took their oscillating particle model quiz on springs. The ones I’m grading so far look great, which is nice to see.
Physics: Projectile Practical
Students worked through a practical to predict where a horizontally launched projectile will hit the floor. Once students got a success, I had them predict which way they should move their target for a relatively light marble.
Chemistry Essentials: Quiz
Students took their quiz on the Bohr model of the atom. Students are starting to feel pretty comfortable reading their periodic tables and anticipating key properties, which bodes well as we move into formula writing.
AP Physics 1: Assessment
Students took their pendulum assessment, initially scheduled for last Friday. They’ve been very quick to grade since students did really well.
Students worked projectile motion problems. A lot of students needed some coaching to remember how to solve problems from a velocity vs. time graph, which tells me we could stand to do a little more spiraling content in the course, but students were pretty successful overall. There was a great moment where a few students were feeling much more confident than usual who objected when someone at their table tried to get help from me before talking about their question with the rest of the table.
Chemistry Essentials: Penny Isotopes
Students used pennies to represent different isotopes of an atom, comparing the average mass of their whole set to the average mass of each type of penny. Because I distributed the pennies pretty randomly, all of the groups ended up with more post-1982 pennies, but I think it would have driven the point home a little stronger if some groups had more pre-1982 pennies.
