Making a weather vane and compass
The earliest weather vane we know about was in Greece in 48 BC, erected in honour of the Greek god Triton. It became quite popular for the houses of the wealthy Greeks around this time to have weather vanes erected on their roofs, and they were often very ornate.
Compasses are used to determine direction and have been used ever since their invention in China approximately 200 years BC. They were in common use as navigation devices as far away as Western Europe by the 1300s. Compasses work on the principle that the Earth has a magnetic field that the magnetic needle aligns to, enabling the direction to be determined.
A simple weather vane
A weather vane is used to determine the direction of the wind.
In this activity, students will construct a simple weather vane and a simple compass. This activity supports the development of the science capabilities, especially ‘Gather and interpret data’, ‘Use evidence’ and ‘Critique evidence’.
By the end of this activity, students should be able to:
build a simple weather vane
build a simple compass
collect data using their weather vane and compass
interpret and make meaning of their data
discuss the reliability of their data.
