For this reason, we rounded up a wide range of Earth Day crafts that will excite and occupy kids of all ages, whilst helping the younger generation understand that caring for our planet is of the ...
3. Ride before you drive. Wherever you need to go on Earth Day, from point A to point B, make it a priority to leave a little earlier and trade your tires for some wheels.
Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and nutation. It also moves with respect to Earth's crust; this is called polar motion. Precession is a rotation of Earth's rotation axis, caused primarily by external torques from the gravity of the Sun, Moon and other bodies.
The pendulum was introduced in 1851 and was the first experiment to give simple, direct evidence of the Earth's rotation. Foucault followed up in 1852 with a gyroscope experiment to further demonstrate the Earth's rotation. Foucault pendulums today are popular displays in science museums and universities. [1]
A rich collection of exciting and imaginative activities [9] covering a wide range of Earth-related topics can be found on the website. Each week an activity is posted on the ELI blog. New activities are published here and comments and suggestions are encouraged. The suggestions are incorporated into ´Extension´ ideas for the activities.

By the era of Early Modern English, capitalization of nouns began to prevail, and the earth was also written the Earth, particularly when referenced along with other heavenly bodies. More recently, the name is sometimes simply given as Earth, by analogy with the names of the other planets, though "earth" and forms with "the earth" remain common ...
Due to the very slow pole motion of the Earth, the Celestial Ephemeris Pole (CEP, or celestial pole) does not stay still on the surface of the Earth.The Celestial Ephemeris Pole is calculated from observation data, and is averaged, so it differs from the instantaneous rotation axis by quasi-diurnal terms, which are as small as under 0.01" (see [6]).
