the-BA : Deep, deep down

The Brits' first fleet of submarines was launched more than one-hundred years ago. But they weren’t met with cheers of admiration because they didn’t fit with traditional military etiquette. Admiral Sir Arthur Wilson, for example, labelled them: “underhand, underwater and damned un-English”. During World War II, Winston Churchill declared the life of a submariner as “the most dangerous of all occupations”.

Have you ever wondered how people breathe in submarines?

You might like to …

• investigate the changes in pressure under water; find out how submarines are built to deal with this pressure
• investigate how to submerge something underwater without it bobbing back up to the surface
• design and build a model submarine
• find out how people in submarines see where they’re going; design and carry out tests to see how much light there would be at the foot of the ocean; design your own periscope
• design and carry out experiments to find out how well sound travels through water
• investigate how sonar works; make your own bat or dolphin detector.
