Wanda and Marita are drinking bottles of water. Each girl sounds a different musical note by blowing across the top of her bottle. What is a good hypothesis that could lead to new experimentation?

It is more fun to play musical notes with carbonated water than with normal spring water.
If the lid on a bottle is tightly closed, then blowing across the top of the bottle will not make a musical note.
Blowing across the top of a bottle can make a musical note.
If there is less water in the bottle, then the note played is lower because there is more air to move around.

they absorb it i think

not sure

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

paper covers rock.
