Properties of Sound

Sound is a noise that can be heard. There are three properties found from the expirement.

The first one is that Sound dissipates as it travels. Dissipates means it gets weaker and weaker. 
The proof is As sound travels is gets lower on a decibel meter.

The propety is that sound travels the same way in all directions. Sound can basically
be same in different positions

The propety is sound can travel around corners. This was observed on the sound meter that was placed around a corner from the sound source.

LI: To observe properties of sound.

Observation I think...	Evidence	Hypothesis ✅ ❎
Sound is louder when is closer to the source but quieter when further away from the source.	Mr Wong meter read 80 DB. Mr Ogilvie meter read 59 DB.	As sound travels it gets lower.
The Sound was basically the same in different positions around the meter.	The meter records the same from the front, back, side and above.	Sound travels the same way in all directions.
The meter rose when Mr Wong went around the corner.	The meter went up when Mr Wong clapped his hand.	Sound can travel around corners
