PurposePurpose

To find out how draughty our house is.To find out how draughty our house is.

It’s SO not that one!

Materials and ProcedureMaterials and Procedure

Cut 1 square of *cling film about 14 cm x 20 cm Cut 1 square of *cling film about 14 cm x 20 cm and *tape it to the *pencil. Now, hold your new and *tape it to the *pencil. Now, hold your new contraption in front of an *open window in your contraption in front of an *open window in your house, then see if the film is blown about in a house, then see if the film is blown about in a draught.

ObservationsObservations

I noticed that since it was a cold, chilly day I noticed that since it was a cold, chilly day in winter, the wind was blowing hard, and in winter, the wind was blowing hard, and the cling film was starting to come off, the cling film was starting to come off, despite the tape.despite the tape.

ConclusionConclusion

The harder the wind blows, the more the The harder the wind blows, the more the cling film will be blown. Opposite of that, cling film will be blown. Opposite of that, the softer the wind blows, the less the the softer the wind blows, the less the cling film will be blown about. SIMPLE!cling film will be blown about. SIMPLE!

The The BIGBIG IdeaIdea

In real life (even though the experiment IS In real life (even though the experiment IS real), scientists will be able to observe the real), scientists will be able to observe the weather easily, and efficiently by using this weather easily, and efficiently by using this experiment ( they don’t use cling film, experiment ( they don’t use cling film, sadly). Well, where do you think the sadly). Well, where do you think the weather reports come from ???????weather reports come from ???????
