Do oranges float or sink in water? Time to find out with this fun science experiment related to density.

Three fun activities involving eggs.

The oceans have always been salty, although most lakes and ponds are not salty. Do things float the same way in a lake or on the ocean?

Next time you have to clean some dishes in the sink, try getting your hands dirty with a little science.

Suzy tests a variety of objects to sort out the floaters from the sinkers. What can you test, at home or at school?

Eggs sink in normal water so what can you do to make them float? Adding salt can give some surprising results.

See some amazing forces in action when you combine a hair dryer with a ping pong ball.

This book focuses on the popular topic of floating and sinking. The medium of water has been chosen because children have many water-related experiences.

We know sea water is salty - with this easy experiment you can find out just how salty it is where you live!

We all love to play in and around water. Why not try having some water fun at home without the need to get into your togs! Let’s see if you can make a waka that can float!

Suzy heads into one of her favourite rooms in the house, for some kitchen science. Do you know why some liquids don't mix? Will water and oil mix? They're both liquids - they should. shouldn't they? Lets find out together.

Pushing and pulling, and floating and sinking - how are they related? In this unit learn about the forces of push and pull and how they work in water and in the air.

A good understanding of the nature and properties of this substance will help children when they come to investigate and understand science concepts about air pressure, floating and flying in air, and the movement of air as it relates to wind and weather conditions.

Joe has created a super fun challenge - to build your very own waka (raft). But not for you. For someone else!

Nanogirl visited Fern on The Moe Show to reveal the science of why boats float.
