The presence of aborigines in Australia for more

Traditional didgeridoos are made from termite
hollowed branches of eucalyptus.

Question?
Mrs. Steele tells the class that her Didgeridoo
was lower in pitch when she first brought it home
from Australia. She wonders why her digeridoo is
higher in pitch now!
6
Some students think that the didgeridoo got
shorter.
Other students think that the didgeridoo was
cracked.
YES, says Mrs. Steele, It was cracked
which makes its pitch higher.

The experiment...

Lets try scotch tape and see if the pitch
gets any lower!

scotch tape over the crack in her didgeridoo.
