The submarines

AFTER you've done your research and concluded your experiments, it is time to prepare for the science fair. Ask specific questions about preparing for a science fair, including how to set up your display board, how to prepare a presentation, etc. (Please post questions about selecting a project or conducting your experiment by posting in the appropriate "area of science" forum.)

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,
Terik
