Weather & Atmosphere

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...
