Summary:
Sound can be affected by all matter such as liquid, solid, or gas. Such as blowing into a bottle. The more water the bottle has the more high pitched the blowing will be. But this is different when hitting the bottle. When the water level is higher the pitch is lower.

SP2: Developing and using models
This week we did a lab where we had a line of bottles in terms of water level. We then blew and hit each one to see what would happen. This is SP2: Developing and using models because we used a model to show how sound works when there is other matter with it.
