Earth's Rotation Day

Earth's Rotation Day is January 8th

This holiday commemorates the day when French Physicist, Leon Foucault, demonstrated the Earth rotating on its axis in 1851.

History

Leon Foucault showed that the plane of the swing of the pendulum rotated relative to the Earth’s rotation, which proved that the Earth rotates on its axis. Today, you can now see the Foucault Pendulum demonstrating the rotation of the Earth in science museums around the world.

How To Celebrate Earth's Rotation Day

A couple ways you can celebrate and observe the holiday is by visiting your local space and science museum to learn more about the Earth’s rotation and what sort of effect it has on humans. If you have kids, you can find ways to make a model of the Earth and the Sun with them so that they can learn more about the Earth’s rotation and how it works.

Earth’s Rotation Day can bring people together by having them share a learning experience in which they can discover the wonders of how the Earth moves on a day-to-day basis. 

Ways to share Earth's Rotation Day on social media

• Using #Earth’sRotationDay, show how you celebrate the holiday on social media
• Make a post on Leon Foucault and his importance for making the discovery of how the Earth’s axis works
• Ask followers for creative ways on how they plan on observing Earth’s Rotation Day
• Share a model you may have made of the Earth and how it rotates
• Encourage followers to make their own Earth’s rotation model

“I shall now recall to mind that the motion of the heavenly bodies is circular, since the motion appropriate to a sphere is rotation in a circle.” - Nicolaus Copernicus
