The humidity level is an indication of the likelihood of rain occurring and this is measured using a hygrometer. Make your own weather predictions by building your own simple hygrometer in the following science experiment.

The 'dewpoint' temperature is the temperature at which the air can no longer hold all of its water vapour, and some of the water vapour is forced to condense into liquid water. The dew point is always lower or...

Water 'evaporates' the fastest in warm, sunny areas. When water evaporates, heat or 'energy' is being drawn from the surroundings, and it cools down such. You can build your own 'fridge' that relies entirely on nature to keep things...

Have you ever wondered what happens to all the water after the snow of a heavy snow storm melts? There is actually a lot less water contained in snow than you might think. Have a look at the following...

Similar to a real tornado, the whirlpool tornado in this science experiment is shaped by very powerful forces. Real tornadoes occur when hot and cold streams of air suddenly collide.

The atmospheric pressure or 'air pressure' can be explained as the 'push' that air exerts on its surroundings at a given point. The air pressure level can also be an indication of the likelihood of rain occurring and this...

An anemometer is an instrument helping us to measure the wind speed. An anemometer has a rotor that spins or turns when the wind blows. The faster is turns, the higher the wind speed is. Build one in the...

The wind direction tells meteorologists what kind of weather they can expect, and the wind speed give them an indication as to how soon that weather is going to reach us. The 'wind vane' is an instrument helping us...

Make your own weather predictions by building your own water barometer in the following science experiment.

Next time it starts raining, be one step ahead of your dad and measure the amount of rainfall with your very own rain gauge. In the following science experiment you will learn how.
