Mina's Recycling Center Notes

1Mina wanted to help workers know when a sorting bin was full. She tested a thin metal lid and a cardboard panel with an elastic strip. She tapped each material three times and watched it closely.

2The metal lid shook and made a ring on 3 of 3 taps. The cardboard panel shook and made a soft thump on 2 of 3 taps. When Mina held the elastic strip still, its twang stopped.

3Next, Mina placed a small foil flag near a speaker. The speaker did not touch the flag. With a tone on, the foil flag moved in 3 of 3 tries. With the tone off, the flag rested in 3 of 3 tries.
