Observing and measuring the wind



              In this lesson you will explore ways to measure
              the wind and look for patterns.                                             Key words

            Scientists use equipment to measure the weather.






                  Making and testing

                  a wind vane


               1  Design and make your own wind vane.


                 Use the picture to help with your ideas.

                 Test that the wind vane spins.

               2  Place your wind vane outside.


                 Make sure it is not too near trees or buildings.

                 Use a compass to find north, south, east

                  and west.

               3  Observe the wind direction every day for

                  five days.

                 Write down your observations in a table.


                                                                                                  Be a

                    from the same direction?                                              Scientists think

                                                                                          about how well

                  Compare your wind directions with some                                  They also

                  reported in weather forecasts for your                                  suggest

                  local area.

                  How could you make your wind vane better?
