Question by Bob S: naturAL WEATHER INSTRUMENT?
how could you build an instrument to predic weather patterns with natural stuff,wood, stuff off of a shipwreck (first aid kit, axe, meals ready to eat, etc.)
Answer by science teacher
There is a hygrometer that is made from a human hair. To learn to tell the weather you need to study cloud patterns and what they mean.
You could set up rain gauge with a marked can.
You could set up a weather vane for direction and it could have a part that swings up to tell speed of the wind.
