as wood does not conduct heat and allows air to move freely
Lol im guessing you had the same geography assignment as i have now...
•Steven sun screen also known as meteorological screen and it is made by wood. •This screen is used at met. Center and it save the instruments from sun light and rain allowing the passage of air.
he invented the instrument
In the 1860s. I think. By Thomas Stevenson.

to prevent heat radiation and damage by people or animals
In observataries,the thermometers are kept in a wooden box with good ventilation and air movement.This box is called stevenson's screen
A Stevenson screen is a ventilation box used to house meteorological instruments, primarily thermometers and hygrometers. It is typically made of wood or synthetic materials and features slatted sides to allow for free air circulation while protecting instruments from direct sunlight and precipitation. The screen is painted white to reflect sunlight and minimize heat absorption. Its design ensures accurate temperature and humidity readings by maintaining a stable environment for the instruments inside.

to support
The Stevenson screen is wooden primarily because wood is a stable material that minimizes temperature fluctuations, helping to maintain a consistent internal environment for measuring meteorological data. Its design provides adequate ventilation while protecting instruments from direct sunlight and precipitation. Additionally, wood is less conductive than metal, reducing the likelihood of heat absorption that could skew temperature readings. Overall, the choice of wood supports the accuracy and reliability of weather observations.
Robert Stevenson did not invent anything. He was a Scottish civil engineer and is best known for his work in designing and overseeing the construction of lighthouses, most notably the Bell Rock Lighthouse in Scotland. Stevenson made significant contributions to the field of lighthouse engineering.
