Earth Clock: The History of Our Planet in 24 Hours

Product Information

Then I removed the origami and I painted the inside of the ball with blue paint, I also painted the outside blue to avoid reflection from the LED ring. After uploading it, you can already see if your circuit works, by pressing either buttons, the motor should spin one way or the other. Spherical white LCD alarm clock with a sleek black multi-function screen that offers a modern yet retro addition to a room. Position yourself to see the Sun or Moon rise over a flat edge – the edge of a building works well, students can watch the Sun come up over the roof of their own house on a clear morning!

Have each student spin through several days so that everyone gets the concept of the diurnal motion of the Sun – and understands that it is caused by the spinning motion of the Earth and that the Sun does not actually move at all! There is also a DIY "maker kit" version of the clock available to classrooms and hobbyists on an open-source basis. At this point, you can decide the color of your Earth: green and blue, black and white… or “realist” like mine.Earth Clock is a computer program that will display a map of the Earth showing the zones where is day and where is night.

Despite unavoidable free services provided by the earth to humans, we are not able to pay off her kindness to us. Damage caused by these environments/conditions are obviously not warranted, therefore no exchanges can be made under the warranty, nor can repairs be carried out as the corrosion from some parts have probably already affected and damaged others parts and materials.

Her illustrations are influenced by a passion for traditional drawing techniques, and they combine rich, vivid colours with explorative, textured brushstrokes.

Unlike our Sun which rises consistently at about the same time each day, the Moon’s rising and setting time changes, rising and setting by almost an hour later each day.

Few years ago, I invented and built a clock showing how the Earth is exposed to the sun in real time.

Your students will learn that the Moon’s rising and setting time are tied to the Moon’s orbital motion and change in a predictable way.
