Quick And Easy Water Fun

Making Fog

All you need to make some Fog in a jar is the following :

*A strainer ( sieve )

*Some ice cubes

*Hot tap water.

What to do ;

Run the hot tap and fill the glass jar 3/4 . Leave the jar for a 2-3 minutes and empty the jar so there is only 1/4 left. Place some ice in the sieve and rest it upon the jar.

Sit back and watch the cold air from the ice cubes hit the warm water in the bottom of the jar !

As the warm air in the jar reaches the freezing cold ice cubes, it condenses into floating droplets suspended in the air , this results in fog .

When warm, damp air moves over cold ground the same theory happens. The air is cooled down and it can no longer hold its water vapour and fog is formed .

The Sinking Sand Castle

The Sinking Sand Castle

All you need to make a Sinking Sand Castle is the following:


*A plastic bowl


* A stop watch

What to do:

Make a sandcastle in your plastic bowl, feel free to decorate your Castle with pebbles or shells.

Dig a small moat around your castle and fill the most with water.

Set your stop watch .

For this experiment we decided to see how long it would take for our Sand Castle to collapse with water surrounding it.

We discussed how long we all thought it would take the water to consume the sand leaving a pile of mushy sand . Our castle lasted 1hr and 3 minutes before it was completely mushy and discussed how water would effect other types of materials such as rock, stone and the effect of sea waves and how that would affect these materials .We spoke about the process of eroding or being eroded by wind, water, or other natural agents.

Boat Or No Float

All you need to make a Boat or No Float is the following:

* A large container or bowl

* Water

* Various items to test so see if it will float or sink

* A hand held fan

We decided to experiment with various objects to determine what would float and what would sink.

What to do:

Place some water in your container.

Take turns to place various items within the water to see what will Float like a bloat and what won't Float .

You can use a handheld fan to see how this effects the movements of the various items.

We also used this experiment to discuss High tides and Low tides ,

By placing a ball in the centre of the container filled with water we noticed the water level didn't change, by gently pushing down on the ball , and adding some pressure we noticed that the water level had risen slightly .

When you release the pressure on the ball you will see the water level lower again.

Every object has gravity , tides are caused by the Moons gravity , this pulls the water in our Oceans into an egg shape, making a bulge at the sides of the world, the Earth spins round but the bulges stay in the same place below the Moon. The bugles move around the world, resulting in high and low tides !
