Materials<br />
A 1.5L plastic soft drink bottle<br />
Water<br />
Instructions<br />
Demonstrate how to produce a sound by<br />
blowing across the top of an empty bottle. Ask<br />
students to suggest what is vibrating. Ask them<br />
what will happen if water is added to the bottle,<br />
and then demonstrate by blowing across the top<br />
of the bottle again.<br />
Ask the students to predict what will happen if<br />
more water is added to the bottle. Let the<br />
students try to make sounds by blowing a steady<br />
stream of air across the top of the bottles.<br />
Group Work<br />
Get students to test out their predictions and record their observations in a table. <strong>The</strong>y<br />
could use a chromatic tuner app to measure the pitch of the sound produced.<br />
Extension:<br />
<br />
<br />
Ask the students to describe how the recorder (music instrument) works.<br />
Get the students to investigate what happens to the pitch if the bottle is tapped<br />
instead.<br />
