Observe and record weather in your area over the coming months. There is resources available to help with:

  • measuring temperature,
  • wind speed
  • rainfall.

Measuring Temperature

The first sighting of the swallow or primrose in flower in spring is a significant event. When scientific measurements are taken the significance lies not in the single measurement but in its place as part of a set, or series, of measurements. Temperature measurements are like this. A single temperature measurement does not tell us much. A graph of temperature measurements taken at the same place, but over a period of time, however, can tell us a lot. It is very important that all these temperature measurements are taken in exactly the same way so that they can be compared fairly.

Measuring Wind Speed

Wind Speed Task

An anemometer is a device that measures how fast the wind is blowing. As such, it is one of the most important instruments to be found in a weather station. The device you are going to build is a model of a real world 'anemo' that will give you an approximation of how fast the wind is blowing. You'll find instructions for making one below.

Measuring Rainfall

Most schools leave their rain gauge out on a Friday afternoon and take a measurement on Monday morning. This measurement is the total rainfall for the weekend. It is important to enter this measurement on your wall chart on Monday so it is included when calculating your weekly rainfall.
