Which of these happens last? Nina hits a drum.
Nina hears the sound of her drum.
Sound waves travel through the air.
The surface of the drum vibrates, creating sound waves.

In their House of Sound, Fran Scott and Greg Foot investigate how drums work.

Drums have been around for thousands of years and throughout history have often been involved in warfare -something they are reminded of as they play along to Mars from Holst’s The Planets suite.

Using confetti placed on a drum they use a slow motion camera to reveal how the confetti behaves like air molecules when the drum is struck.

The skin of the drum vibrates and makes the confetti dance.

As the air molecules vibrate against each other, sound waves are formed and the sound of the drums can be heard.

Fran explains that the pitch of a drum depends on how tight its skin is. If the skin is tight the drum makes a high note, if it is slack it makes a low note.

Greg points out the amount of air inside a drum also influences its pitch. The more air in a drum, the lower the note. The less air in a drum, the higher the note.

Volume depends on the size of the vibrations that are made.

Hit a drum hard and this makes big vibrations and a loud sound.

Hit a drum softly and the vibrations are smaller and the sound not as loud.

Together they make a drum kit out of things that can be found around the house, and Fran shows us how to make fun drums out of a plastic bowl and half a balloon.

everyman: morality play

which phrase in this excerpt from the play everyman refers to god's judgment of people's souls after their death?

messenger: . .

ye think sin in the beginning full sweet,

which in( the end) causeth thy soul to weep,

when the body lieth in clay.

here shall you see how fellowship and jollity,

both strength, pleasure, and beauty,

will fade from thee as flower in may.

for ye shall hear, how our heavenly king

calleth everyman to a (general reckoning):

give audience, and hear what he doth say.

god: i perceive here in my majesty,

how that all the creatures be to me unkind,

living without dread in worldly prosperity:

of (ghostly sight) the people be so blind,

drowned in sin, they know me not for their god;

in worldly riches is all their mind,

they fear not( my righteousness), the sharp rod;

(my law that i shewed), when i for them die

hopefully this !
