In a spin
Further work on "forces" can be explored as pupils
consider submarine propulsion and how propellers work. They can
consider which combination
of shape, pitch and number of blades work best. |

Up periscope!
Looking through periscopes can teach pupils about the effects of light
in a fun and practical way. They can explore how light travels and is
reflected from surfaces.

Got the message
Pupils can see a range of historical and contemporary forms
of submarine communication and discover how they work. They
can listen to the sonar "ping" and
investigate how sound travels.

Feel the force
Pupils can learn how submarines dive
and surface by changing the amount of air and water in the ballast
tanks. They can explore buoyancy and the upward force of water and the
downward force of gravity. They can look at why submarines are the shape
they are and which shape creates least friction. Click

Material matters
There is lots of scope for work on materials and their properties.
Pupils can find out about the properties of materials used
in submarines and what
made them a "good" or "bad" choice and why a different
material is used today. They can examine the clothes worn by submariners
to suit different purposes and conditions and find out how the salt is
removed from seawater to create fresh water. |
