Make a pine cone weather station

A simple way to record the weather

Equipment

a pinecone◊ A pine cone

 

Method

1. Place the pine cone on a window sill.

2. Have a look at the pine cone every day and
record whether it is open or closed. Is it raining?

Pine cones are full of very light seeds. They open on fine, dry days so that the wind can carry the seeds far away from the parent tree. On days when the humidity is higher, the seeds are less likely to be carried away, so the pine cones remain closed.

Borrow an Instrument

Did you know the Royal Meteorological Society lends instruments to schools free of charge?

Clouds in the real world form in warm, moist air. You can make something similar happen using things you can find around your home.
