Duct tape, a hoopla hoop, and a steel bearing. First, we made predictions. Then we tested (multiple times, of course!!)
Teacher tip: dry erase markers work on waxed tile flooring

Today, in #AlvaPhysics:
⚙️Wrapped up the mobile project
⚖️Discussed stability & center of mass
🔎Ex: ca. 1800's Hamilton "torpedo" bottle
🧮Mass of rod in single mass mobile was determined with < 2% error!
Water Balloon drop day in #AlvaPhysics today!
✅determine v_avg (walking speed)
✅measure h (walker height)
✅measure H (ladder height)
🏁Determine Δx to pair freefall & walking paths/times
We solved for this 4 different ways in #AlvaPhysics yesterday...same solution each time! #iteachphysics
🧮 Iteratively
⚖️Proportional Reasoning
📈Equations of lines
➗Algebraically
What to do with all of those extra conference @pascoscientific "I ❤️ Physics!" bumper stickers? Accessorize your constant v buggy lab! 🚗 #AlvaPhysics
Today in #AlvaPhysics: the Physics #Boom Lab (more like an exercise in problem-based learning)
Notes on board were built up incrementally as the hour went on, so not all at once but mirroring student groups' lead/progress
Previously, in #AlvaPhysics, Bumper Carts designed to minimize F_av. Total impulse determined (thanks, @VernierST !). Winning cart is in the video. 3D printed awards assembly coming soon!!
Today in #AlvaPhysics: creating conservation of momentum problems with a subtle error embedded in them. On Monday, groups will and present as part of review! (Idea inspired by @kellyoshea https://t.co/0PXs3qnsNq)
Don't break Eggbert! 🥚 #AlvaPhysics
It's time for the annual #PinkiePieParachuteChallenge! Tomorrow, #AlvaPhysics Ss will vie for bragging rights, attempting to maximize her descent time with their creations!
Today, I trolled my HS #AlvaPhysics class with notes in GroupMe (homecoming week = lots of absences)
In #AlvaPhysics, Ss determined my position on ground that a water balloon would need to be released from rest above so it would hit my head (moving at constant v). Water balloon released from rest, 23m above using a fire truck ladder 🚒 💧 🎈
Giant tennis ball 🎾 vs. sopping wet roll of toilet paper 🧻 💦 dropped from rest on a @VernierST force plate. Physics says the F_avg experienced should be different... and they are! Which one should be greater? By how much? Why? #AlvaPhysics #iteachphysics
Impulse Bumper Challenge! Kaden wins!! 🏆Sage’s “Boat” will be the source of height and width constraints for the future! #AlvaPhysics #GoldbugPride
Yesterday in #AlvaPhysics class. E conservation for a roller coaster. But KE_f < PE_i. So we talked about work done by non conservative forces. #TheTitleOfMyTEDTalk: Let me introduce my non-conservative force friend, friction.
#Physicspenpal postcards from Arkansas & China received! We are working on two sets to go your way @treddtaylor & @learnwithhart soon!! #AlvaPhysics
Busy week this week for #AlvaPhysics! #MarsLanding!, #PinkiePie parachute challenge award ceremony🏅, revisiting graph matching📈📉, the moment of inertia race of slowness, and trying out Cornell Notetaking 📝 #teach180 #iteachphysics
This week in #AlvaPhysics: The #PinkiePie Parachute Challenge! Each person has the same materials & must build a parachute. Longest time of descent & most accurate wins! There will be an award ceremony! #iteachphysics #teach180
