Rhiannon: Curse Of The Four Branches Hints

How can I determine which sound goes with which symbol?

  • 1 of 18: There is an item in the house which will prove absolutely invaluable in solving this conundrum.
  • 2 of 18: Thank God for secondary school education!
  • 3 of 18: Check Rhiannon's bedroom and you will find some of her physics homework. It relates to different materials having different resonant frequencies.
  • 4 of 18: It talks about wood, paper, plastic, and ceramics, which have low to high resonant frequencies in that order.
  • 5 of 18: You now need to take a listen to the four recordings that you made with the MP3 player, and use your ears to place them in a similar order.
  • 6 of 18: Put them in an order from lowest tone to highest tone.
  • 7 of 18: The electrical generator sound is the lowest.
  • 8 of 18: The bathroom fan is higher than this.
  • 9 of 18: The refrigerator from the kitchen is higher than that.
  • 10 of 18: And, the sound of water from the waterwheel is the highest of all.
  • 11 of 18: Now, link those four sounds with those four types of material, and take a look at the four symbolic objects that you collected today.
  • 12 of 18: Notice anything? Particularly about what those objects are made of?
  • 13 of 18: We have a wooden wand, a paper calendar, a plastic hat, and a ceramic piggybank.
  • 14 of 18: These are the correct matches. Wood had the lowest resonant frequency, and the generator had the lowest sounding tone. These two are matched.
  • 15 of 18: The wooden wand goes with the sample of the electrical generator.
  • 16 of 18: The paper death shroud calendar goes with the sample of the bathroom fan.
  • 17 of 18: The plastic hard hat goes with the sample of the refrigerator.
  • 18 of 18: And finally, the ceramic piggybank goes with the sample of the waterwheel from the mill.
