we're working with bottles today, why not have a special treat that reminds us
of yesteryear: milk in a bottle! Many grocery stores offer organic milk in
returnable glass bottles, and it's rich and creamy. They have flavors such as
chocolate and orange, too. Pair your delicious, ice-cold bottled milk with a
couple of graham crackers.
Glass bottles or jars: same size is
best, and 8 would be great
Pitcher and access to water
Thin masking tape | spoon
Collect as many glass bottles or jars as you can.
Pour different amounts of water into each jar.
Mark the water levels of notes you like with masking tape.
Add food coloring to make the jars look pretty.
Tap each bottle with a spoon. Make a melody!
Experiment. If you want a higher note, do you add more water, or pour
some of the water out?
An "octave" is an eight-note scale that is central
to most Western music. See how that word starts with an "oct-" as a prefix, the
same as an octopus (eight-legged sea creature) or an octagon (eight-sided
figure)? You can remember that "octave" means eight notes because of that
It'll be challenging, but see if you can make an
octave out of the different levels of water in your jars.
