The submarines

Postby wootchelmine » Sun Dec 28, 2014 5:56 pm

My topic is about the submarines and my question is : How and why the submarine float and sink. I did some researches but my problem is that I have some difficulties to make my hypothesis ?

Hi wootchelmine,

I apologize that it's taken so long for someone to respond to your question! A hypothesis is an educated guess about what you think will happen in your experiment. What is the scientific question you are trying to answer? It sounds like you have a general topic (buoyancy of submarines). Have you been able to formulate your testable question?
All the best,
