CA Play it again, Sam. - 3 glasses of each of 3 different sizes
and shapes (9 glasses total) - 4 glasses of the same size and
shape - different liquids like vinegar, water, milk, tomato
juice, maple syrup, oil or apple juice - Check with a grown-up
before you begin. - In the ZOOMsci, Glass Xylophone, and in the
online gizmo, Tunes & Spoons, you can experiment with the
different sounds made by glasses holding different amounts of
the same liquid. - Now's your chance to experiment with other
variables like the kind of liquid in the glass or the size and
shape of the glass itself. - First, find out if different kinds
of liquids change the sound made by tapping the glass with a
spoon. - Pour the same amounts of different kinds of liquids
into the same kind of glass. Try liquids that are thick and
gooey like maple syrup as well as liquids that are runny like
water. - Tap the same spot on each glass. Do the different
liquids produce different sounds? Ho
