The Submarine. The submarine allows people to go deep underwater and explore the sea life. They are very important when it comes to war because they deliver weapons and are very sneaky about it.
Why? • Marine Biologists wanted to find out more about the underwater life so they have gotten more high tech so that they could go further and find out more. • Some say it was originally invented in the 1500’s but in 1578 William Bourne took credit for the invention.
In Time
• Submarines are big and small and have progressed tremendously over time.
