@RobSpencer1 @MrJoeMilliano How did the swinging happen? Did students hold the wooden planks and swing them?

@MrJoeMilliano Designed a lab in which circling mass was unknown but Ss could measure length and collect tension values for varying known frequencies from metronome online. Plotting T vs f^2 yields line related to mass. All theoretical masses were less by 20% to experimental...

@SICKOFWOLVES yay thank you!

@maalmeida85 Using Fr=Ia. the students timed for 2.5 rot(length of rip cord) to find a. for F, attached different masses to the wheel and released it.

I always avoided rotational inertia labs, but this year I'm giving it a try. Class lab to determine. rot. I of a wheel. #iteachphysics

@onarug2pointo context?

@BairdDr25972 Thank you for posting this. This is awesome. Can you explain why the spider is EQS?

@PhilipMRussell1 I was looking for a lab that had students measure the mag. force! What did you use for the magnet holder? Is that a special kind of wire? What gauge?

#iteachphysics Floating Eraser! EM feels like magic at times

Toilet Paper Lab! It'll be a staple from now on. I loved it. Always interesting to see how a lab challenges Ss differently than practice problems #iteachphysics

#iteachphysics ! has anyone done the toilet paper drop/unrolling activity for mechanics? if so can you give me some tips? How much scaffolding was given? How much time do you give? TY!

@phyzman grasped! I get it.

@swampphysics I honestly never fully grasped(!) why it was fairly trivial for me and so impossible for most students. But we kinda lost track of the exact quantitative principles amid all the laughter.

Balanced Torque lab! one of my favorites to do with the Ss. I think I found a budget set up that I'm happy with. Strings & Binder Clips for the fulcrum. Ss can perform the lab standing and at any location #iteachphysics

@McClowny woa. that's a good idea. I teach them the finger slide trick but I've never had them do it with hanging masses.

@swampphysics My Ss used to be so amazed that they could find center of mass by sliding their fingers toward each other under the meter stick. Then, of course, they started trying it out with masses hanging from it.

@Misterfizzx it cuts down on me telling them to use the metric side. every time I hear the Ss remind each other that they're using the wrong side during labs it's a good reminder that's one less time that I'll ever have to remind them

@swampphysics WRONG SIDE!?😂

@phyzman 100% I'll do this. ty for the idea!

@swampphysics It appears you and your students may be ready for the Torque-Master Challenge. phyzblog.blogspot.com/2019/02/torque…

Motors! Ss found out that they can adjust the rotations by pressing on the sides #iteachphysics

@Hookean1 thank you!
