Description

This is a classic physics classroom demonstration as modified for use in remote teaching/distance learning (RT;DL). Please guide your students through this lesson.

A dumbbell is suspended from a sturdy horizontal support. Another string is attached to the bottom of the dumbbell. The bottom string is then pulled downward until one of the strings breaks. Which string breaks and why?

The way I wrote this allows students to contemplate the possibilities of what could happen. But rather than make a prediction, they are allowed to request an outcome. This is somewhat jarring since they are usually tasked with predicting. It take a few moments for the "Total Request Live" aspect to sink in. Once it does, they usually vote for the outcome they don't think should happen. For this TPT remastering, I encourage that explicitly in the presentation.

I wrote a post to my Blog of Phyz when I initially reworked this demo for RT;DL.
