How can we explore underwater?

The underwater world was opened up by pioneers like Jacques Cousteau with the development of the aqualung. This allowed scientists and explorers to spend longer underwater and discover more about the coral reef and other habitats.

One of the problems of working together underwater is the inability to speak, and so divers have developed a range of dive signs to communicate with one another. Learn the dive signs and then play the Dive sign game. If you have time, then have a go at the Animal dive signs activity as well.

The live lesson will review these activities and look at a range of different technologies used to explore the underwater world.

Remember that questions and shout outs can be submitted up to 24 hours in advance for booked lessons via your user profile.


The live lesson assumes that students and families will have completed the Dive signs game and Animal dive signs activities.

There are two videos that will help. What kit do coral researchers need? covers the basics of the equipment needed to scuba dive, and What are dive signs and what do they mean? is a fun recap of the basic dive signs.

As a long weekend activity think about making your own reef in a box. A fun and creative way to prepare for the live lessons the following week.
