One of the properties of sound is that it can travel in every direction when sound travels it dissipates (it gets weaker).
I know this cause when Mr Wong clapped on one side of the class room the meter on the other side of the classroom didn't move. if your far away from the sound you can't really hear it but if your close to the sound then you can hear it. Another properties of sound is that sound can travel around corner.
L.I To observes the properties of sound
Properties of Sound
PROPERTY: a characteristic that something is known by. For example, a property of ripe strawberries is that their colour is red.
OBSERVE: to watch and remember what happened.
EXPERIMENT: to observe what happens to something when different conditions are imposed on it.
CONDITION: a state of being.
IMPOSE: to make someone or something do something.
HYPOTHESIS: a prediction or evidence based guess that can be tested to find the truth.
What properties of sound can you figure out? There will be a bunch you can figure out by just experimenting with sound. Watch the video to find out how to do the experiment.
Fill out this table with your observations and hypotheses about the properties of sound.
You will need to use a sound meter like this free online meter by Youlean.

Sound is louder when it’s closer to the source and quiet when the sound it’s far away from the source | When Mr Wong bounced the ball far away from the Source the meter was low. and when he bounced the ball near the meter | When sound travels it gets softer or weaker |
| The meter recorded the same sound on the top,bottom,and the sides but it was basically the same number. | Sound can travel around corners |
