Neutral Buoyancy Experiment

Hello this is a picture about me Mahana & Jessica did for our Neutral Buoyancy Experiment. I hope you enjoy and please leave me a comment.

This is a list of things that you will need when you go diving

Sink or Float

This term we have been learning about

buoyancy. Buoyancy is the ability to push things up to float and if it is heavier than the surface it will sink. Here is my experiment

The lightest wood in the world

Today we have been Reading a book named The Lightest Wood In The World. This book is about a kind of wood named Whau. Did you know that Whau is lighter than cork

Orange	Float	F / S
apple	Float	F

Diet Coke	Float	F
Coca-cola	Sink	S
Scissors	Sink	S

 

Why do some things float while others sink?

Some things float because if it is heavy than the water it will sink but if it is lighter it will float. If you put something in the water and it floats in the middle that is called neutral buoyancy.
